Back End Developer

This is a Senior Backend Engineer position with real architectural authority. You will lead key projects from concept through to production, drive backend architecture decisions across high availability, cloud native infrastructure and mentor the engineers around you. The work spans distributed systems, scalability challenges, observability and major platform initiatives - the kind of problems that build a career.

What sets this role apart is the quality of the engineering bar. The hiring manager is not looking for a CV that ticks boxes. He is looking for engineers who can go deep - who can pick a complex project from their background and explain exactly what they built, why they made the architectural decisions they did, what trade-offs they navigated and what impact their work had. If that is how you think about your work, you will feel at home here immediately.

AI usage in engineering workflows is also important here. The team uses AI tooling heavily day to day - tools like Copilot, Cursor and Codex are embedded in how engineers work. You do not need to have built AI models, but you should be using AI actively in your development workflow and be able to talk about how it improves your output.

The tech is Go and Java across backend services, GCP cloud infrastructure, Docker and Kubernetes, high availability distributed systems design and modern CI and CD pipelines., If you are a strong Java or Go engineer who can go deep on your work and is ready for a role that will genuinely challenge and reward you, please reach out to Nick Napier directly on LinkedIn or submit your CV via the link below.

• 10 or more years of professional software engineering experience, including 5 or more years focused on backend development
• Advanced proficiency in Go and/or Java with a deep understanding of distributed systems
• Hands on experience with cloud infrastructure, ideally GCP, and containerised environments including Docker and Kubernetes

• The ability to explain your architectural decisions, trade-offs and individual impact in depth - not just at a surface level
• Active use of AI tooling in your engineering workflow
• Strong communication skills and a collaborative, proactive working style
