Senior Platform Engineer; Azure

As a Senior Platform Engineer, you will lead the design, evolution, and reliability of the core platform that underpins our engineering ecosystem. You will set technical direction, define standards, and drive best practices that enable product teams to deliver securely, efficiently, and at scale.

Your role goes beyond implementation, you will shape the platform strategy, influence architectural decisions, and act as a technical leader across teams.

This is a hybrid role with occasional onsite collaboration — typically once every 2–3 months, but you are able to attend our offices as much as you like, — at either our Welwyn Garden City or Liverpool offices. From time to time, you may also travel between sites.
