Senior Frontend Engineer at Tessian
London, GB

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

-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!


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.
