Codurance is a software craftsmanship consultancy. We work with clients on the engineering problems that actually matter to their business, and we do it properly - clean code, sound architecture, and engineering practices that hold up under pressure, not just in a demo. We're not a body-shop; our consultants are expected to bring technical judgement and push back on bad decisions, not just fill a seat.

We're hiring contract .NET Engineers to join a project team working on a large-scale modernisation programme for a client in the regulated financial services space - replacing a legacy platform that's been patched together for years with a modern, cloud-native architecture running on Kubernetes. It's meaty, high-stakes engineering with real constraints around compliance, data integrity, and scale, and you'll be doing it alongside a team that cares about doing the work well.

You'll be embedded with the client's engineering teams as part of a Codurance delivery squad, working on:

• Re-architecting parts of a legacy system onto modern, cloud-native foundations
• Building and evolving services on Kubernetes across AWS and Azure
• Working in a regulated environment where quality, testing, and traceability aren't optional
• Applying proper software craftsmanship practices - TDD, pairing, clean architecture - as standard.

Requirements

• Strong commercial experience with .NET / C# in a production environment
• Experience with cloud platforms (AWS or Azure) and containerised/Kubernetes environments
• Comfortable working in a regulated or compliance-heavy environment (financial services experience is a plus, not a requirement)
• Experience modernising or re-platforming legacy systems
• A genuine interest in doing things well - testing, clean code, good engineering habits
• Able to work in Manchester 1-2 days a week
