Senior Software Engineer - Server Side (C# / Worker Service / ORM)
Waterlooville, Hampshire | Up to £85,000 + Benefits | Onsite | 4 or 5 day week
Some projects are maintenance. Some are migrations. And then something genuinely rare comes along - a blank canvas, a serious engineering challenge, and a product deployed on military vessels around the world.
A well-established international technology company is building a brand new System from scratch. The pace is fast - there's a client demo in January. You'll be among the first engineers into the UK team, with a clear expectation that early hires grow into team lead roles.
The Role
You'll be at the heart of the system architecture, building the server-side framework that underpins everything. Clean, modular C# using a Worker Service pattern, a reusable common framework, and direct interfaces to sensors, effectors, and external systems. Production-quality engineering where simplicity, precision and pace all matter.
