You'll lead technically and, in most cases, lead people too — owning delivery outcomes for a client engagement and setting technical direction. You're expected to be full stack in practice: comfortable owning a backend built in a strongly typed language, equally comfortable in the front end, and hands on with the infrastructure and delivery pipeline underneath it all. Most of your week will be spent working alongside client teams ,sometimes fully remote, sometimes on site. You'll need to be able to get into London on short notice when a client needs it, so anywhere up to around two hours out is fine. • A strongly typed backend language — .NET or Java — paired with genuine front-end capability across JS/Node/TypeScript., • Ownership of the full delivery pipeline: CI/CD, infrastructure as code (Terraform or equivalent), testing built in as standard., • Leadership experience — ideally a couple of stints at lead level owning a cross-functional team and its outcomes. If you're a staff engineer who's owned the technical direction without formally managing people. for more information please get in touch. #J-18808-Ljbffr
