Frontend at Tessian Read more about Engineering at Tessian: https://stackoverflow.com/jobs/companies/tessian

At Tessian, our mission is to keep the world’s most sensitive data and systems private and secure. Our platform uses machine intelligence to understand human communication at scale, allowing us to protect some of the world’s largest organisations from threats executable by humans.

From a Frontend perspective, we have two main challenges at Tessian: concisely communicating security insights from millions of data points back to our clients through analytics and dashboards, and ensuring all our users find our portal easy to use, despite its industry-leading level of sophistication and flexibility.

We are building a Design System and component library using a modern stack consisting of TypeScript, React, Emotion and Styled System.

As a Frontend Engineer, you will play an integral part helping us to finish the migration and achieve consistency, great user experience and great developer experience. We use mainly TypeScript and React, so, preferably, you should be comfortable with those, but that is not an absolute requirement if you have experience with JavaScript and another Frontend framework. If you're also able to use a little Python to plug our frontend into our backend that's a plus!

You'll have 3+ years of experience working in frontend development and be able to work to a high technical standard. More junior than this? Check out our non-Senior frontend role instead. We'd love to meet someone who:

  • Is a great problem solver who takes pride in their work
  • Has good knowledge of Javascript, and a frontend framework
  • Enjoys the challenge of working with and presenting summaries of large datasets
  • Has passion for learning new skills and technologies
  • Has ideally worked on large, complex Enterprise dashboards before
  • Is ideally equally comfortable working on frontend and backend tasks

Tech Stack:

  • TypeScript / JavaScript
  • React
  • Css-in-JS / Emotion / Styled-System
  • Python 3
  • Docker / CI Pipelines
  • AWS

Data Science at Tessian

Our mission is to secure the human layer. This involves deploying near real-time machine learning models at massive scale to some of the world’s largest organisations to keep their most sensitive data private and secure. To do this, we're looking for a senior data scientist with NLP experience ready to work on hard problems, drive best practice and cultivate an environment of experimentation and learning. Companies can leverage data science in a number of ways, and we think the role of a Data Scientist falls into three distinct categories:

1) You work for a business function analysing & reporting on how to improve a key metric, e.g increasing user conversion

2) You are responsible for writing production models to enhance the main product, e.g recommendation systems for e-commerce

3) You are the product - without machine learning, it wouldn't exist

The Data Science team built the product at Tessian. We couldn't exist without our machine learning models; it’s at the heart of what we do, and it’s what our clients rely on day-to-day. We're searching for a Lead NLP Data Scientist who is excited about the opportunities and challenges that come with researching, building and deploying real-time production models. In this role you'll get to:

  • Work across massive enterprise email datasets
  • Deploy models to production that impacts directly our customers and products
  • Improve our ML workflow
  • Collaborate with engineering and product leaders to develop a product suite that is continually detecting more advanced threats for our customers
  • Make your mark on leading ambitious projects
  • Mentor and knowledge share with data scientists at Tessian

We'd love to meet someone who:

  • Has 6+ years Data Science experience
  • Has strong NLP experience (in production)
  • Has worked with, or understands the principles behind working with data at scale
  • Can balance longer term projects alongside impactful quick wins
  • Cares deeply about the impact their team hasIs a creative at heart, and can encourage novel ways of thinking in their team. This has always been a core part of the data science team’s DNA
  • Reads Rules of Machine Learning - Martin Zinkevich and it resonates with how they think about machine learning and data science


Job Benefits:

  • A full week of work-remote a year for non-remoters +25 days of holiday
  • Choice First! Flexible working hours and working from home
  • We’re family friendly, with policies built to support you
  • High-quality tech kit provided for you including Tessian ANC Headphone
  • If you're relocating, we'll provide a contribution to help with costs

What will your responsibilities be?

  • Support the vision and execution for the infrastructure for a fast growing missing critical SaaS product.
  • Short term technical delivery within the team as well as setting the long term vision.Note that this does not include line management.
  • You will work with the Head of Engineering and many stakeholders (tech leads in other teams) to define your team’s roadmap.
  • Day to day operation and security of the platform comes under you, with a focus on empowering other teams to improve their velocity.

We'd love to meet someone who:

  • Has at least 5 years of AWS and “DevOps” experience
  • Has experience with stakeholder management or as a product owner.
  • Is a great problem solver who takes pride in their work.
  • Enjoys building scalable and resilient systems, with a focus on systems that are robust by design and suitably monitored.

In this role you'll get to:

  • Work across massive enterprise email datasets
  • Deploy models to production that impacts directly our customers and products
  • Improve our ML workflow
  • Collaborate with engineering and product leaders to develop a product suite that is continually detecting more advanced threats for our customers

  • Has strong NLP experience (in production)
  • Has worked with, or understands the principles behind working with data at scale
  • Can balance longer term projects alongside impactful quick wins
  • Cares deeply about the impact their team hasIs a creative at heart, and can encourage novel ways of thinking in their team. This has always been a core part of the data science team’s DNA
  • Reads Rules of Machine Learning - Martin Zinkevich and it resonates with how they think about machine learning and data science

They are also not ‘mini-CEOs’ who call all of the shots.   Product managers at Tessian own a product or product area. Within this area, product managers are responsible for a) delighting customers and b) driving Tessian’s growth. Product managers work with engineering, data science, and product design to shape and ship new products and functionality, and with Tessian’s go to market teams to make their product successful.   Our product, whilst highly technical, should deliver a best-in-class user experience where complexity is hidden. As a senior product manager you’ll be a creative, technical thinker who is as equally comfortable getting into the weeds of a specific problem as pulling back to ensure the product vision is successfully aligned to achieve our ambitious mission.  We are looking for someone with 3+ years of experience scaling and shipping products at high-growth technology companies. Experience with security or products built for enterprise is a bonus. As a Senior Product Manager you will:
  • Identify opportunities that can change the trajectory of Tessian’s business 
  • Manage the roadmap by prioritizing the highest impact initiatives from a wide range of inputs
  • Shape and ship new products and features, in collaboration with engineering, data science, and product design 
  • Drive growth by ensuring Tessian’s value proposition is resonating in the market, in collaboration with Tessian’s go to market teams

Product at Tessian

Having found exceptional product/market fit for our category-defining Human Layer Security software platform, we’re in the midst of transitioning from 'start-up' to ‘scale-up’, and are looking for a Senior Product Designer to join our team. 

Product Designers at Tessian work closely with our autonomous, cross-functional engineering teams to deliver amazing experiences for our customers. As part of the Product team, Product Designers work flexibly and are able to utilise UX, UI and Product skill sets. 

We’re not a typical cybersecurity company, and we need someone who can communicate this through impactful UI and UX design. Our main design challenge is creating analytics dashboards and visualisations to communicate trends detected by Tessian in massive email datasets. You might also work on rethinking complex workflows, or designing friendly interactions for our end-users. 

The new senior product designer will have significant impact in defining the design process at Tessian. We value collaborative design, and use Figma for UX/UI work. We’re looking for someone hands-on that values the impact design can have over perfection.

We’re open to a variety of experience levels and would love to meet someone with startup or b2b SaaS experience.

How does the hiring process work?

You'll meet a number of Tessians over three rounds of video calls. We'll ask you about your portfolio and background and run some small in person design challenges. 

We've come up with a great way to assess candidates during our process so we won't ask you to do a take home challenge.

We'd like to meet someone who:

      • Has 3+ years experience working and collaborating with engineering teams in dynamic environments
      • Can showcase an outstanding portfolio including a strong foundation in both visual and interaction design
      • Has experience closely partnering with product managers to develop the strategy and rationale for features 
      • Is comfortable working on complex, open ended design challenges
      • Prefers building new products over optimising old ones
      • Bonus - experience designing b2b web portals
      • Bonus - experience designing analytics or visualisation tools

Why we think you'll love it here....

It’s important to us that all Tessians are part of the journey we’re on, so we offer equity options with every role and benchmark to provide above market rate salaries - there’s plenty more too….

Be at your best, both inside and outside of work

  • 25 days of paid holiday (including an additional day for every year you've worked at Tessian!)

We're looking for an experienced DevOps Engineer for the Platform Team at Tessian. The Platform Team is responsible for defining and operating the infrastructure upon which our development teams and customers depend.  This will be someone experienced in both platform engineering (including Terraform) and software engineering (we use Python). Why is this role exciting:

  • We have plans for fast growth in terms of customer numbers and our Engineering team.
  • We have an ambitious product vision and a strong team determined to execute on it.
  • We solve hard problems - scale, big data (Spark/EMR), security, large databases (PostgreSQL, DynamoDB) and complex integrations.
  • Your work will leverage the work of our 50+ strong engineering team and all of our customers.
  • You will help to provide internal tooling to automate and enable self-service to increase development efficiency.

What are our current and upcoming projects:

  • A large migration from AWS ECS to Kubernetes - in the past few years it has become clear to us that using AWS ECS is slowing us down. We have an ambitious goal to migrate most of our platform to Kubernetes by the end of the year, with an aim of speeding up our engineering teams. 
  • Providing tooling to increase development velocity and security - we aim to provide tooling to automate and enable developers to deploy to production, while providing safeguards to prevent issues. 
  • Bolstering our security and deployments for Enterprise - we intend to close more enterprise deals and have a plan to do it. A key project we plan to start will be creating a deployment method that allows us to maintain developer velocity whilst also giving reassurances to security conscious customers. 
  • Keeping the lights on as we scale to bigger customers - a crucial part of this role is to ensure that our systems remain reliable and working with engineering teams to drive quality and solve problems.

What will your responsibilities be:

  • Improve efficiency by finding and fixing gaps in our tooling
  • Maintain and support business-critical systems
  • Enable developers to ship code to production every day using CI/CD techniques
  • Tackle the challenges that come with processing highly sensitive data
  • Make your mark on ambitious projects

We'd love to meet someone who:

  • Has at least 5 years of AWS and DevOps experience.
  • Can design and write code, preferably in Python or if not is excited to learn Python.
  • Is a great problem solver who takes pride in their work.
  • Has strong experience managing a range of production applications in a distributed and highly available AWS environment.
  • Has experience with and is opinionated about containerization (Docker) and a container orchestration system (e.g. ECS/Kubernetes).
  • Has experience with infrastructure as code (Terraform).
  • Has a deep understanding of Linux operating system and administration skills, and shell-scripting skills.
  • Has a deep understanding of server/network security concepts and implementations.

We believe that our product, whilst highly technical, should deliver a best-in-class user experience where complexity is hidden. As a Senior Frontend Engineer, you will play an integral part in rebuilding our portal from the ground up to help us achieve this.  

From a Frontend perspective, we have two main challenges at Tessian; concisely communicating security insights from millions of data points back to our clients through analytics and dashboards, and ensuring all our users find our portal easy to use, despite its industry-leading level of sophistication and flexibility. 

You should be comfortable with Javascript and a frontend framework. If you're also able to use a little Python to plug our frontend into our backend that's a plus!

You'll have 3+ years of experience working in frontend development and be able to work to a high technical standard.

Dealing with massive datasets at scale requires ingenuity and strong analytical skills. Our approach to problem solving means we favour hiring engineers who pride themselves on the ability to learn new skills, their comfort with the unknown and their willingness to experiment.

We're looking for an experienced DevOps Engineer for the Platform Team at Tessian. The Platform Team is responsible for defining and operating the infrastructure upon which our development teams and customers depend.  This will be someone experienced in both platform engineering (including Terraform) and software engineering (we use Python). Why is this role exciting:

  • We have plans for fast growth in terms of customer numbers and our Engineering team.
  • We have an ambitious product vision and a strong team determined to execute on it.
  • We solve hard problems - scale, big data (Spark/EMR), security, large databases (PostgreSQL, DynamoDB) and complex integrations.

  • Providing tooling to increase development velocity and security - we aim to provide tooling to automate and enable developers to deploy to production, while providing safeguards to prevent issues. 
  • Bolstering our security and deployments for Enterprise - we intend to close more enterprise deals and have a plan to do it. A key project we plan to start will be creating a deployment method that allows us to maintain developer velocity whilst also giving reassurances to security conscious customers. 
  • Keeping the lights on as we scale to bigger customers - a crucial part of this role is to ensure that our systems remain reliable and working with engineering teams to drive quality and solve problems.

What will your responsibilities be:

  • Improve efficiency by finding and fixing gaps in our tooling
  • Maintain and support business-critical systems
  • Enable developers to ship code to production every day using CI/CD techniques
  • Tackle the challenges that come with processing highly sensitive data
  • Make your mark on ambitious projects

We'd love to meet someone who:

  • Has at least 5 years of AWS and DevOps experience.
  • Can design and write code, preferably in Python or if not is excited to learn Python.
  • Is a great problem solver who takes pride in their work.
  • Has strong experience managing a range of production applications in a distributed and highly available AWS environment.
  • Has experience with and is opinionated about containerization (Docker) and a container orchestration system (e.g. ECS/Kubernetes).
  • Has experience with infrastructure as code (Terraform).
  • Has a deep understanding of Linux operating system and administration skills, and shell-scripting skills.
  • Has a deep understanding of server/network security concepts and implementations.

Product at Tessian

Having found exceptional product/market fit for our category-defining Human Layer Security software platform, we’re in the midst of transitioning from 'start-up' to ‘scale-up’, and are looking for a Senior Product Designer to join our team. 

Product Designers at Tessian work closely with our autonomous, cross-functional engineering teams to deliver amazing experiences for our customers. As part of the Product team, Product Designers work flexibly and are able to utilise UX, UI and Product skill sets. 

We’re not a typical cybersecurity company, and we need someone who can communicate this through impactful UI and UX design. Our main design challenge is creating analytics dashboards and visualisations to communicate trends detected by Tessian in massive email datasets. You might also work on rethinking complex workflows, or designing friendly interactions for our end-users. 

The new senior product designer will have significant impact in defining the design process at Tessian. We value collaborative design, and use Figma for UX/UI work. We’re looking for someone hands-on that values the impact design can have over perfection.

We’re open to a variety of experience levels and would love to meet someone with startup or b2b SaaS experience.

How does the hiring process work?

You'll meet a number of Tessians over three rounds of video calls. We'll ask you about your portfolio and background and run some small in person design challenges. 

We've come up with a great way to assess candidates during our process so we won't ask you to do a take home challenge.

We'd like to meet someone who:

      • Has 3+ years experience working and collaborating with engineering teams in dynamic environments
      • Can showcase an outstanding portfolio including a strong foundation in both visual and interaction design
      • Has experience closely partnering with product managers to develop the strategy and rationale for features 
      • Is comfortable working on complex, open ended design challenges
      • Prefers building new products over optimising old ones
      • Bonus - experience designing b2b web portals
      • Bonus - experience designing analytics or visualisation tools

  • You will help to provide internal tooling to automate and enable self-service to increase development efficiency.

What are our current and upcoming projects:

  • A large migration from AWS ECS to Kubernetes - in the past few years it has become clear to us that using AWS ECS is slowing us down. We have an ambitious goal to migrate most of our platform to Kubernetes by the end of the year, with an aim of speeding up our engineering teams. 
  • Providing tooling to increase development velocity and security - we aim to provide tooling to automate and enable developers to deploy to production, while providing safeguards to prevent issues. 
  • Bolstering our security and deployments for Enterprise - we intend to close more enterprise deals and have a plan to do it. A key project we plan to start will be creating a deployment method that allows us to maintain developer velocity whilst also giving reassurances to security conscious customers. 
  • Keeping the lights on as we scale to bigger customers - a crucial part of this role is to ensure that our systems remain reliable and working with engineering teams to drive quality and solve problems.

What will your responsibilities be:

  • Improve efficiency by finding and fixing gaps in our tooling
  • Maintain and support business-critical systems
  • Enable developers to ship code to production every day using CI/CD techniques
  • Tackle the challenges that come with processing highly sensitive data
  • Make your mark on ambitious projects

We'd love to meet someone who:

  • Has at least 5 years of AWS and DevOps experience.
  • Can design and write code, preferably in Python or if not is excited to learn Python.
  • Is a great problem solver who takes pride in their work.
  • Has strong experience managing a range of production applications in a distributed and highly available AWS environment.
  • Has experience with and is opinionated about containerization (Docker) and a container orchestration system (e.g. ECS/Kubernetes).
  • Has experience with infrastructure as code (Terraform).
  • Has a deep understanding of Linux operating system and administration skills, and shell-scripting skills.
  • Has a deep understanding of server/network security concepts and implementations.

At Tessian, our mission is to keep the world’s most sensitive data and systems private and secure. Our platform uses machine intelligence to understand human communication at scale, allowing us to protect some of the world’s largest organisations from threats executable by humans. 

We believe that our product, whilst highly technical, should deliver a best-in-class user experience where complexity is hidden. As a Senior Frontend Engineer, you will play an integral part in rebuilding our portal from the ground up to help us achieve this.  

From a Frontend perspective, we have two main challenges at Tessian; concisely communicating security insights from millions of data points back to our clients through analytics and dashboards, and ensuring all our users find our portal easy to use, despite its industry-leading level of sophistication and flexibility. 

You should be comfortable with Javascript and a frontend framework. If you're also able to use a little Python to plug our frontend into our backend that's a plus!

You'll have 3+ years of experience working in frontend development and be able to work to a high technical standard.

Dealing with massive datasets at scale requires ingenuity and strong analytical skills. Our approach to problem solving means we favour hiring engineers who pride themselves on the ability to learn new skills, their comfort with the unknown and their willingness to experiment.
