Technical jobs in United Kingdom

DLG is evolving. Across every facet of our business, our teams are embracing new opportunities and putting customers at the heart of everything they do. By joining them, you’ll have the opportunity to not just be recognised for your skills but encouraged to build upon them and empowered to do your absolute best.

At Darwin Insurance, a brand within DLG, you’ll help build the next generation of our low‑latency, cloud‑native data platforms — the systems that power real‑time pricing, machine learning workflows, and operational intelligence. You’ll own the design of resilient ETL/ELT pipelines, distributed data processing, and scalable AWS infrastructure, collaborating closely with a tight‑knit team of engineers, architects, and product leaders who care deeply about doing things the right way.

We engineer like a startup: Clean Code, TDD, CI/CD, Infrastructure‑as‑Code, full ownership, and a bias for shipping well‑designed, well‑tested systems. You’ll have a genuine voice in architectural direction, mentor strong engineers, and help raise the technical bar across the team.

This role is ideal for someone who wants meaningful impact — someone who’s excited by the blend of startup autonomy and big‑company reach, and who wants to shape the future of Darwin’s data platform as we scale our ambitions.
