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.

Understand and appropriately implement the WCAG (Accessibility) principles, guidelines and success criteria implemented
iOS and Android app store submissions, code signing/provisioning, TestFlight/Play Console, Fastlane, phased rollouts, and OTA update strategies (e.g., CodePush/EAS Update)
Strong understanding of data structures and architectures, using relational and/or non-relational database approaches with the ability to query using SQL
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
Experience of release processes and governance
Experience of full-stack software development principles, architecture and conventions
Experience of a wide range of SLDC methodologies, including Waterfall, Agile Scrum, Kanban, behavioural-driven development (BDD), and continuous integration
