Where do you fit in? You’ll join as a full-stack engineer in London, that leans more in to back-end. Working closely with agency leadership and client architecture teams. You’ll shape high-quality engineering practices: building reusable components, ensuring strong pipelines, and delivering production-ready software that can be confidently handed over. This is a role for someone who enjoys breadth and ownership: context-switching across languages, improving pipelines, and collaborating across teams.
