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
