About the Role

Join OneAdvanced

We're looking for a Principal Software Engineer to provide senior technical leadership across our engineering teams. Someone who brings deep architectural thinking, a bias for shipping, and the credibility to raise the bar for everyone around them.

This is a hands‑on role. You'll design and build complex, scalable systems while setting the technical standards that shape how we work. You'll influence engineering direction at an organisational level, champion best practices, and help grow the engineers around you. Not by managing, but by leading through craft and example. If you're energised by hard technical problems, care deeply about code quality, and want your work to have real impact beyond your own output, this role was built for you.

This is a hybrid role based out of Birmingham, with the expectation that the successful candidate will attend the office 1–2 times per week, as required.
