About The Role
What if the code you write could directly power the AI systems shaping how millions of people interact with technology?
We're looking for Back End Developers based in London to design, build, and optimize the server‑side systems and APIs that drive cutting‑edge AI products — from data pipelines and model‑serving infrastructure to scalable microservices that handle real‑world traffic at scale.
This is a fully remote, flexible contract role.
Whether you're a seasoned engineer looking for meaningful project work or a strong developer ready to apply your skills to AI‑adjacent infrastructure, this is your chance to build things that matter.
