What to expect

The Lead Developer will define the technical direction, lead and mentor a team of Senior and Mid‑Level Software Engineers, and own the end‑to‑end development and delivery of the Post Office Mobile Travel App and in‑branch Government Service applications.

Our priority lies in shaping a business that mirrors the diverse communities we reach, truly making Post Office 'Everybody's Business'. As an equal opportunity employer, we value and celebrate the differences among our people, ensuring that our practices reflect our dedication to inclusivity and equal representation for all.

A strong understanding of test-driven development and testing conventions
Experience of developing and supporting RESTful APIs
Practical experience designing and maintaining CI/CD pipelines (GitHub Actions), including automated builds, tests, static analysis, security scans, and release automation
