Insight into the role

Our market is competitive, and our customers deserve even more, so we’re constantly evolving. Recently we’ve launched an exciting new product strategy as the North star for the entire organisation.

We have big, interesting problems to solve on the journey, and need the best talent in the industry to take us to that next level.

Our platform engineers use their expertise in building and maintaining infrastructure and tooling to help enable our developers to create innovative products and services which are blazingly fast and reliable. They want our developers to be able to deliver safely and securely, and they work closely with them to build platform solutions to support this. Our aim is to enable our product engineering teams to own the services they build.
