*Frontend at Tessian*

We’re looking for a Frontend Team Lead to help us rethink the Tessian dashboard. We are building an Enterprise dashboard that sits on top of our machine learning platform that our clients can use to configure our various products as well as query the threats we’ve detected.

You should be comfortable with Javascript, SQL and a frontend framework (ideally React). If you're also able to use a little python to plug our frontend into our backend that's a plus! You'll get to work on designing and developing a brilliant and complex React app.

Dealing with massive datasets at scale requires ingenuity and strong analytical skills. Our agnostic 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.
