Job description

Senior Software Engineer | C# / .NET

• Build greenfield solutions as part of a major AI transformation programme
• Join a high-calibre engineering team working on next-generation technology
• Play a key role in a multi-year programme with real scope to make an impact

A leading global organisation is investing heavily in a multi-year technology and AI transformation programme, building new capabilities from the ground up rather than simply modernising what already exists.

This is an opportunity for a Senior Software Engineer to join a highly-calibre, specialised team focused on designing and building new solutions across software engineering and AI. You’ll work in a fast-paced environment where engineers are given ownership, expected to solve complex problems, and encouraged to take ideas from concept through to production.

With a strong focus on Agentic AI, RAG and MCP, you’ll be working at the intersection of traditional software engineering and emerging AI technologies — building robust, scalable solutions that can operate in a real-world enterprise environment.

Why You’ll Love This Role

• Greenfield from the ground up — design and build new solutions rather than simply maintaining legacy systems.
• AI at the heart of the programme — work directly with agents, RAG and MCP as the organisation develops its next generation of AI capability.
• Highly-calibre team — work alongside experienced engineers and AI specialists with a strong focus on engineering excellence.
• Multi-year programme — join at an early stage with significant runway and the opportunity to shape what comes next.
• Fast-paced environment — solve challenging problems, move quickly and see your work make it into production.
• Real ownership — you’ll be trusted to take responsibility for solutions from design through to delivery.

What You’ll Do

• Designandbuildscalable,production-readysoftwaresolutionsusingC#and.NET.

Key Requirements

• 10+ years’ professional software engineering experience, with strong hands‑on development experience.
• Strong C# / .NET experience, ideally across modern .NET, APIs and distributed/microservice‑based systems.
• 1–2 years’ hands‑on experience building AI agents, with practical experience working with MCP and RAG.
