Senior Platform Engineer

As a Senior Platform Engineer, you’ll play a key role in designing, delivering and improving secure, reliable and scalable technology platforms that enable our Engineering Squads to work efficiently and independently.

You’ll help create a self-service engineering environment that reduces complexity and unnecessary hand-offs, while championing a strong DevOps culture where teams take end-to-end ownership of their systems. Providing technical leadership and guidance, you’ll act as the technical lead on key projects and initiatives, promoting best practice across security, resilience, performance and availability.

Working across both Agile and traditional delivery environments, you’ll collaborate with Engineering and wider Technology teams to remove barriers and support high-quality delivery at pace. As a senior member of the team, you’ll also support and deputise for the Infrastructure Manager when required.
