As a Frontend Engineer in our automatic optimization team, you will use your skills to build new capabilities to our core product and make sure our customers find the tool efficient, easy to use and most importantly valuable. You will work as part of an independent fullstack team, so communicating with other engineers, product managers and designers, and even customers is essential.

The main focus of our team is to build automated optimization and A/B testing tools for our customers. While this means that we use advanced Bayesian modeling in the backend, we do our best to make everything as easy as humanly possible to our customers. Our customers are not statisticians, after all. And frankly, as a frontend developer, you don’t need to be, either.

Our current frontend stack consists of React typed with Flow and Typescript. Oldest parts of the codebase still use AngularJS, so being able to read AngularJS and refactor it to React is a plus.
