Valerann is a fast-growing Smart Cities startup, based in London and Tel Aviv. We work with the world’s largest infrastructure operators to transform roads into data-generating assets. Through our work and partnerships, we look to reshape the way operators use data to make traffic safer, more efficient, and support autonomous vehicles. If you want to be part of a dynamic and award-winning start-up and help shape the future of mobility - join Valerann!

We are developing a traffic management solution that is based on a unique vehicle-level data fusion. We ingest streams of data (IoT, Video, Social feed) into our AWS cloud environment; we run machine learning algorithms to identify various traffic issues and feed them back in real-time to vehicles and traffic control centres. We have made huge progress, but we need your help to move to the next level.

Our London-based team is looking for a talented, experienced and dedicated front end developer. Your primary focus will be developing and improving our web app which is in use in highways control centres in Europe and around the world. You will develop user interface components and implement them following well-known React.js workflows (such as Redux, Storybook). You will work closely with our product manager and our data engineers/scientists team.
