Full Stack Lead Engineer

We want to hire ambitious, and value-adding talent into Modulr, one of the fastest growing payments businesses in the UK and Europe. Modulr is experiencing significant growth, and in this role you will work in a cross-functional team who are asked to solve a problem, rather than be handed a task to do. This is an excellent opportunity to work in a high-growth environment with a fast-paced and collaborative culture where you will have great opportunities to work on challenging problems across the entire technology stack.

The Full Stack Lead Engineer is a vital role within Modulr, where you will be responsible for building an autonomous, high performing engineering squad to foster an environment where decisions are delegated, made and communicated effectively. You will drive technical strategy with a strong emphasis on Python and FastAPI backend development while remaining deeply hands-on with core development. The role is a blend of hands-on Python development, technical leadership, mentoring, and operational excellence.

You will lead the architecture and implementation of robust, scalable backend systems using FastAPI, cloud infrastructure on AWS, and coordinate full-stack solutions with frontend teams.
