Site Reliability Engineer

Summary

Wikimedia Foundation is hiring a Site Reliability Engineer (SRE) to join our SRE team, where we take care of the infrastructure that runs wikipedia.org and other Wikimedia Foundation projects. We are responsible for the entire infrastructure stack, from multiple data centers, through networking and interconnects, to 1000s of servers and the application stack that runs on them.

We are a distributed and diverse team of engineers with a drive to explore, experiment and embrace new technologies. We are along the path of transitioning our platform from a monolith to a hybrid microservices architecture and have implemented these microservices on our on-premises Kubernetes platform with an in-house designed deployment pipeline. We’ve adopted the Elastic Stack and Prometheus as our de facto logging and monitoring platforms. We automate the operational tasks with a mix of technologies, mainly Python and Puppet. We ensure the availability and reliability of one of the most used sites on the Internet, and develop the software we need to achieve these goals - for example our automation platform “spicerack” (https://github.com/wikimedia/operations-software-spicerack) which we use to develop cookbooks for repeatable tasks (we ❤️ automation).

We work in the open and document our work on our internal task management system (https://phabricator.wikimedia.org) and our technical wiki (https://wikitech.wikimedia.org). Feel free to check out our activities there.

We are avid supporters of open source software. If you have interesting open source contributions, let us know!

If you find what we do interesting and you enjoy the idea of working with a globally distributed team that runs a Top-15 website, we may be the place you’re looking for.

As an engineer in the SRE team you will be involved in defining and running the infrastructure and services that form the base of Wikimedia Foundation projects. This will include frequent work with other members of the SRE team to improve our infrastructure in terms of scalability, high availability, recoverability, monitoring and logging. You will participate in incident response and be oncall. You will also be frequently interacting with people not in SRE, like Security, Release and Software Engineers, who all strive to maintain and make Mediawiki and related software better.

We use more technologies than we can list here and are interested in your experience even if it doesn’t exactly match the keywords above / below.

You are responsible for:

• Implementation and maintenance of Internet facing infrastructure and services
• Use of configuration management and deployment tools
• Monitoring of systems and services, optimization of performance and resource utilization
• Common operating system level tasks such as logging and backup / restore
• Cookbook / runbook implementation for common maintenance actions
• Incident response, diagnosis and follow-up on system outages or alerts
• Collaborating with a global and asynchronously communicating team (don’t worry if you have never worked remotely, we’ll help you get used to it)

Skills and Experience:

Qualities that are important to us:

• 2+ years experience in an SRE/Operations/DevOps role
• Experience with operating highly available infrastructure
• Comfortable with shell and a programming language used in an SRE/Operations engineering context (Python, Go, Ruby, etc.)
• Experience with package management for operating systems (Debian, etc)
• Comfortable with Open Source configuration management and orchestration tools (Puppet, Ansible, TerraForm etc.)
• Past exposure to automation and streamlining of tasks
• Communicative technical English

Additionally, we’d love it if you have:

• A history of contributing to Open Source projects
• Prior participation in the Wikimedia movement

Summary

Come build the premier mobile Wikipedia experience! The Wikimedia Foundation is looking for an iOS Software Engineer to join our team, reporting to the Apps Engineering Manager. You will work closely with the rest of our small, collaborative group to iterate on new ideas for the award-winning Wikipedia iOS app. In this role, you will create new features, fix bugs, and define the future of Wikipedia on mobile devices.

Each day, millions of people use the open source Wikipedia app in over three hundred languages. Help us thoughtfully craft user experiences that empower and delight our users as they read and contribute to the world’s largest resource for free knowledge.

You are responsible for:

• Writing clean, concise code in Swift
• Working with other engineers through discussions, code review, and more
• Collaborating with designers, product managers, and other engineers to iterate on new features
• Ensuring the quality of the app through thoughtful code architecture decisions and automated testing

Skills and Experience:

• At least 1 year of iOS development experience. (Our iOS engineers are excited to share knowledge and tips they’ve picked up over the years - and also look forward to learning from you!)
• At least one app in the iOS App Store that you’ve contributed to. (We’d love to see what you’ve been working on.)
• Familiarity with the iOS Human Interface Guidelines and their implementation. (We’re creative, while staying true to best iOS practices.)
• Excellent written and verbal communication skills (Our team is remote, but we still enjoy close collaboration!)

Qualities that are important to us:

• A desire to learn and discover - about iOS development, about what the root cause of an obscure bug is, about how the Wikipedia communities operate, and more.
• Constantly improving your craft in pursuit of creating the best possible user experiences and solving complex problems
• Proactively finding and reporting potential bugs or user experience issues for discussion with the team
• We are a global organization with flexible work schedules, but we’re also collaborative. To ensure there are enough opportunities to communicate, this role needs at least four hours of your work day to occur between 14:00 UTC and 0:00 UTC.

Additionally, we’d love it if you have:

• Some Objective-C experience. Like many apps that have been around for a while, the Wikipedia app is a mix of Swift and some legacy Objective-C code. While you don’t need to be an Obj-C expert, you shouldn’t be terrified if you end up in an Objective-C class while tracking down the source of a bug.
• Written unit and UI tests
• Built web services or APIs
• Built frontend web applications using JavaScript, HTML, and CSS
• Experience collaborating with a globally distributed team
• Contributed to Wikipedia or other open projects

PRINCIPAL DATABASE ARCHITECT

Summary

Wikimedia is looking for a Principal Database Architect to join our SRE team to design, build, optimize and support the platform serving the world’s favorite encyclopedia to millions of people around the globe. Wikipedia and its sister projects are a globally distributed architecture powered strictly by Free and Open Source software. The stack has MediaWiki at its core, surrounded by an ecosystem of microservices in PHP, NodeJS, Python, Go and Java.

The Wikimedia developers and community continuously expand and improve the software powering the Wikimedia projects. The common step in this process is finding optimal ways of storing data and fine-tuning the code that interacts with data storage systems (including schema and query optimization).

We currently use MariaDB as our main RDBMS and Cassandra as the dominant NoSQL solution. We are interested in finding new and improved ways of utilizing the capabilities of the existing stack as well as researching and potentially implementing other similar products. To achieve these goals we are looking for a candidate with strong experience, both hands-on and in a consulting capacity, in designing, developing and operating large scale database systems with complex dependencies.

We are a globally distributed and diverse team of engineers with a drive to explore, experiment and embrace new technologies. If you find what we do interesting, if you are up to the challenge of improving the reliability and delivery of one of the Internet’s top 10 websites, and you enjoy the idea of working in a remote-first role, Wikimedia may just be the right place for you.

You are responsible for:

• Working with developers, SREs and other teams, providing guidance on optimizing queries, schema design and overall data strategy.
• Assisting at every step of the architectural design and development lifecycle of new services and making them operate at scale
• Designing, improving and operating the RDBMS and NoSQL systems serving Wikimedia projects
• Researching, testing and benchmarking new RDBMS and NoSQL solutions
• Responding to common database issues, following documented procedures
• Assisting in or leading incident response, diagnosis and follow-up on system outages or alerts across Wikimedia’s production infrastructure
• Mentoring peers in your areas of technical and operational strength
• Sharing our values and work in accordance with them

Skills and Experience:

• Deep knowledge of (Free and Open Source) RDBMS (MariaDB, MySQL) administration (good understanding of and experience with replication is essential)
• Deep knowledge of debugging query performance and schema design
• Strong programming language skills and experience designing and developing software using relational databases at large scale
• Familiarity with (Free and Open Source) NoSQL products (Cassandra, Redis, Elasticsearch, etc.)
• Strong requirement analysis and problem solving skills
• Strong English language skills and ability to work independently, as an effective part of a globally distributed team
• B.S. or M.S. in Computer Science or equivalent work experience

Additionally, we’d love it if you have:

• Experience working with SRE/Operations/DevOps teams
• Experience with shell and scripting languages used in an SRE/Operations engineering context (Python, Go, Bash, Ruby, etc.)
• History of automating tasks and processes, identifying process gaps and finding automation opportunities
• Low level systems troubleshooting and debugging (CPU/memory profiling, C/C++ experience, in-depth Linux knowledge)
• Experience with LAMP stack technologies (PHP/HHVM, memcached/redis, MySQL) - MediaWiki familiarity would be great!
• Some experience developing Free and Open Source software, or being part of an open-source community

Senior Site Reliability Engineer

Summary

The Wikimedia Foundation is looking for a Senior Site Reliability Engineer to join our team, reporting to the Search Platform Engineering Manager. As the Senior Site Reliability Engineer, you will be responsible for supporting, maintaining and extending Wikidata Query Service (WDQS), the essential infrastructure that supports querying Wikidata and our Search infrastructure, powering the searchbox on Wikipedias and other higher level features..

The Search Platform team is dedicated to “help people easily discover knowledge on Wikipedia and its sister projects by providing tools and infrastructure for casual readers and expert users with precise needs, while maintaining a strong emphasis on privacy.” We are a mixed-skill team composed of software engineers, a computational linguist, and a site reliability engineer. We are responsible for Search and the Wikidata Query Service. We are a fully remote team, spread across UTC-8 to UTC+1 timezones. When the world is not locked down by a pandemic, we see each other in person two or three times per year.

Wikidata Query Service is a SPARQL endpoint, backed by a graph database (more precisely an RDF Triple Store) that is live updated from Wikidata. WDQS provides the means to query Wikidata, to ask questions that would otherwise be impossible to answer, and to provide the base infrastructure on which our community can build tools and bots to query and edit Wikidata. We’ve written a great blog post if you want more context.

Wikidata has recently reached item number 10’000’000. Our graph database contains almost 12 billion triples, and has grown by over 250 million triples over the last three months. This is one of the largest public SPARQL endpoints on the internet. You would be helping us support this rapid growth.

CirrusSearch is the Mediawiki extension, backed by Elasticsearch, that provides Search capabilities to all of our wikis, serving around 2000 requests per second. We do Machine Learning Ranking and other data centric approaches to Search, supported by Kafka and Hadoop.

Your job as part of this team would be to use your skills to help us maintain and scale the Wikidata Query Service and Search. Your first project is likely to be setting up an Apache Flink cluster on Kubernetes that will allow us to update Wikidata Query Service more efficiently. This platform has the potential to become our new standard for stateful stream processing across the Foundation.

Here are some examples of projects we have been (or still are) working on:

• Rearchitecting and rewriting the update process that ships data from Wikidata to WDQS, introducing Apache Flink as a stateful event processing framework.
• Integrating Wikidata and Search.
• Maintaining the beta Wikimedia Commons Query Service (WCQS) SPARQL endpoint and upgrading it to production status.
• Rearchitecting our Elasticsearch cluster to allow for additional growth in the size of our indices, splitting into more independent Elasticsearch clusters.

You are responsible for:

• Deployment, scaling, monitoring, provisioning and support of our Search and SPARQL endpoints
• Providing guidance and expertise to the team on productionizing our applications

Skills and Experience:

• Experience as a Site Reliability Engineer, experience working on bare metal is a plus.
• Experience with Configuration Management Systems (Puppet, Ansible, …)
• Experience in supporting highly available and high-traffic web-facing applications.
• Be open to supporting JVM-based applications.
• English language skills and ability to work independently, as an effective part of a globally distributed team.
• B.S. or M.S. in Computer Science, related field, or equivalent in related work experience. Do not feel you need a degree to apply; we value hands-on experience most of all.

Qualities that are important to us:  

• Be passionate about free culture / open source

Additionally, we’d love it if you have:

• Experience with search
• Experience with graph databases, in particular RDF / SPARQL
• Experience with event streaming platforms (Kafka or similar)

Summary

The Wikimedia Foundation is hiring a Senior Site Reliability Engineer to support and maintain the data and statistics infrastructure that powers a big part of decision making in the Foundation and in the Wiki community. This includes everything from eliminating boring things from your daily workflow by automating them, to upgrading a multi-petabyte Hadoop cluster to the next upstream version without impacting uptime and users.

We're looking for an experienced candidate who's excited about working with big data systems. Ideally you will already have some experience working with software like Hadoop, Kafka, Spark and other members of the distributed computing world. Since you'll be joining an existing team of SREs you'll have plenty of space and opportunities to get familiar with our tech, so there's no need to immediately have the answer to every question.

We are a full-time distributed team with no one working out of the actual Wikimedia office, so we are all together in the same remote boat. Part of the team is in Europe and part in the United States. We see each other in person two or three times a year, either during one of our off-sites (most recently in Europe), the Wikimedia All Hands (once a year), or Wikimania, the annual international conference for the Wiki community.

You are responsible for:

•     Integrating an open-source GPU software platform like AMD ROCm in Hadoop and in the Tensorflow-related ecosystem
•     Improving the security of our data by adding Kerberos authentication to the analytics Hadoop cluster and its satellite systems
•     Building the Foundation's new event data platform infrastructure
•     Implementing alarms that alert the team of possible data loss or data corruption
•     Building a new and improved Jupyter notebooks ecosystem for the Foundation and the community to use
•     Upgrading the cluster to Hadoop 3
•     Replacing Oozie by Airflow as a workflow scheduler

Skills and Experience:

•     2+ years experience in an SRE/Operations/DevOps role as part of a team
•     Experience in supporting complex web applications running highly available and high traffic infrastructure based on Linux
•     Comfortable with configuration management and orchestration tools (Puppet, Ansible, Chef, SaltStack, etc.), and modern observability infrastructure (monitoring, metrics and logging)
•     An appetite for the automation and streamlining of tasks
•     Willingness to work with JVM-based systems  
•     Comfortable with shell and scripting languages used in an SRE/Operations engineering context (e.g. Python, Go, Bash, Ruby, etc.)
•     Good understanding of Linux/Unix fundamentals and debugging skills
•     Strong English language skills and ability to work independently, as an effective part of a globally distributed team
•     B.S. or M.S. in Computer Science, related field or equivalent in related work experience. Do not feel you need a degree to apply; we value hands-on experience most of all.

ENGINEERING MANAGER, TRUST & SAFETY

Summary

The Trust & Safety Engineering Team at Wikimedia Foundation is looking for an Engineering Manager to lead the team in building features that help protect our users’ privacy and safety on all of our Wikimedia projects, including Wikipedia. This role is full-time, 100% remote, and global.

The T&S Engineering Team is a new, interdisciplinary product team developing tools that help our T&S staff and the volunteer admins they work with to enforce policy, procedure, and laws across our projects and communities. This includes some light data analysis tools and some enforcement tools.

We are seeking an Engineering Manager to guide the engineering team in this fight to protect our users and our projects. Stopping harassment on our projects is a pillar of our Foundation’s strategy and planning for the future. Alongside the Anti-Harassment Tools Team, this team will be focused on tools that help protect and empower the most vulnerable people in our communities. This is important, highly visible work. 

While the Anti-Harassment Team has been around for a few years, this team is brand new. You will be responsible for helping to set the culture of your team as it fits inside the larger culture of the Wikimedia Foundation. Some of the team’s engineers may already be on the team when you join. However, you will be tasked with hiring for any open roles on the team. Your stakeholders will be Trust & Safety experts that cross disciplines from Legal to Security as well as all the users impacted by these topics.

Because of the sensitive nature of the tools we build, our work is highly collaborative and heavily tested. We interact with database administrators, security engineers, and other teams on a regular basis.

We use open source tools as much as possible, and always open source our own work (check out our Github). PHP and JavaScript make up most of our code, but we value using the right tool for the job. 

Our world is vast and can be complicated, so we value communication, enthusiasm, and eagerness to learn as much as certificates or degrees.

Responsibilities

• Lead a team of engineers to deliver product within the larger product plans of the org
• Model empathetic, servant leadership that encourages growth through learning
• Provide technical oversight and decision-making when needed
• Plan the growth of the engineers on your team including skill sets and career planning
• Organize the team’s workflow and software development methodology along Agile ideas
• Collaborate with other technical leaders for effective cross-team execution
• Build effective schedules and processes for the globally distributed team

Requirements

• Experience managing a globally distributed team
• Proven success delivering software at scale
• People-first philosophy that focuses on individual growth as the foundation for team success
• Strong written communication skills as our collaboration largely happens online
• Bachelor’s degree in CS or related field or the equivalent in work related experience

Nice to Haves

In addition to the basic skills needed for being successful, these skills could set you apart from the pack!

• Experience with MediaWiki development or as a contributor to Wikimedia projects
• Understanding of the free culture movement
• Experience with machine learning or AI technologies
• Experience with online community moderation or anti-harassment tools

Summary

The Anti-Harassment Tools Team at Wikimedia Foundation is looking for a Staff Software Engineer to work with us to build features that help identify and stop harassment on all of our Wikimedia projects, including Wikipedia. This role is full-time, 100% remote, and global.

The Anti-Harassment Tools Team is an interdisciplinary product team developing tools that help administrators and staff in their efforts to combat these people who would use our projects to harm civil discourse, the integrity of the content, or other users of our projects. This includes some light data analysis tools and some enforcement tools.

We are seeking a software engineer to join us in this fight to protect our users and our projects. Stopping harassment on our projects is a pillar of our Foundation’s strategy and planning for the future. This is important, highly visible work. Currently, we are working on a broad set of tools related to user privacy and protection. You can see more details in our backlog.

The team is fully staffed with a Product Manager, Engineering Manager, Product Designer, Research Analyst, Data Analyst, Community Liaison, Test Engineer, and several Software Engineers, of course. 

Because of the sensitive nature of the tools we build, our work is highly collaborative and heavily tested. We interact with database administrators, security engineers, and other teams on a regular basis.

We use open source tools as much as possible, and always open source our own work (check out our Github). PHP and JavaScript make up most of our code, but we value using the right tool for the job. Developers at the Foundation have autonomy and responsibility, and can have a large and immediate impact on the future of the site and the movement. Our world is vast and can be complicated, so we value communication, enthusiasm, and eagerness to learn as much as certificates or degrees.

Responsibilities

• Develop, test, and deploy new features, improvements and upgrades to various systems and tools used by administrators and staff
• Work with Foundation staff and volunteers on software design, development, testing and evaluation of potential technical solutions
• Ensure positive and constructive discussions with the community and the Foundation
• Work and communicate effectively within a small team distributed across multiple time zones

Requirements

• Education and/or experience with Object-Oriented development using a scripting language (such as PHP, Python, Ruby, or JavaScript). Most of our work is in PHP and JavaScript
• Interest in front-end web application development skills
• Openness to working with a diverse and geographically distributed team
• Strong written communication skills as our collaboration largely happens online
• Bachelor’s degree in CS or related field or the equivalent in work related experience

Nice to Haves

In addition to the basic skills needed for being successful, these skills could set you apart from the pack!

• Experience with MediaWiki development or as a contributor to Wikimedia projects
• Experience with unit testing and integration testing and agile methodologies
• Any other free/open source software development experience is highly welcome
• Understanding of the free culture movement
• Experience with machine learning or AI technologies
• Experience with online community moderation or anti-harassment tools

Show us your stuff!

If you have any existing open source software that you've developed (these could be your own software or patches to other packages), please share the URLs for the source. Links to GitHub, etc. are exceptionally useful. This is optional and your candidacy will not be negatively impacted if you don’t have public work to share.

• Operating and helping to improve the design of the CDN edge of Wikimedia’s infrastructure
• Responding to common traffic issues following documented procedures
• Performing day-to-day operational tasks on Wikimedia’s public facing infrastructure (deployment, maintenance, configuration, troubleshooting)
• Utilizing configuration management and deployment tools
• Monitoring systems and services
• Assisting with incident response, diagnosis, and follow-up on system outages or alerts across Wikimedia’s production infrastructure
• Sharing our values and working in accordance with them

Skills and Experience:

• Some experience working as part of an SRE/Operations/DevOps team, or similar
• A working knowledge of the core protocols of the Internet, especially TCP/IP, DNS, HTTP, and TLS
• Operational experience with one or more open source HTTP server and/or proxy softwares (such as Apache, Nginx, Haproxy, Envoy, Varnish, ATS, etc) running on a Linux server platform.
• B.S. in Computer Science or equivalent work experience

Qualities that are important to us:

• Some programming and/or scripting experience solving real problems in any language
• Strong English language skills and ability to work effectively and often asynchronously as part of a globally distributed team  

Additionally, we’d love it if you have:

• Familiarity with the debugging and performance tracing of HTTP requests through various proxy/caching layers
• Familiarity with global Internet infrastructure and routing
• Comfort with shell and scripting languages used in an SRE/Operations engineering context (Python, Go, Bash, Ruby, etc.)
• Low level systems troubleshooting and debugging skills
• Prior experience contributing to Free and Open Source software projects or communities in any capacity
