About us

User experience design is at the core of everything we do. The products we create are grounded in real world problem solving and are designed to compel users to interact with data. Established over 6 years ago, we have grown a client list of some of the worlds leading fintech companies and investment banks. Our portfolio is second to none and we are growing our team.

We only hire exceptional talent, but equally important is that you fit well with our team and culture. Our people are our biggest asset and we collaborate throughout the creation of our products - both with our team and with our clients. At Fathom we have IA / UX designers, UI / Product designers and Front-end engineers, but for us it’s the combination of these skills that enable us to design truly innovative products.

If you are someone that isn’t afraid to get involved, are a great communicator and want to work somewhere where you are truly challenged, in a relaxed environment, working with one of the best teams in London, then we’d love to hear from you.


Working on an existing highly sophisticated React application, you'll be the sole developer owning and shaping delivery of new features and improvements. The application is architected in such a way that it is devoid of business logic in the UI, instead the back end is holding all state and informing the UI how to present itself through WebSocket subscriptions. This is an opportunity to work on an application that thinks differently and performs at high benchmarks in a fast pace trading environment.

As the main engineer on the project, you'll be responsible for the delivery of new features to the platform as well as supporting the clients back end team in architecting new ideas. This role is based the majority of the time in the client's office - an investment bank near Bank station.
