Job Description

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.

Stack

C# / Worker Service, greenfield from scratch
ORM, NHibernate / Entity Framework, SQL database design and creation
DI, Unit Testing, modular 3-tier architecture
Message Bus, Pub/Sub, SignalR, gRPC, TCP/IP, Sockets, Data Flow TPL

Modular, composable architecture design - N-tier and message-based systems
Experience interfacing with hardware devices or real-time data
Eligible for SC security clearance 

Onsite in Portsmouth / Havant (circa 30-person office). 40 hours over 4 or 5 days with some flexibility. Degree in Software Engineering or related discipline preferred.
