Principal Developer St Helens / Warrington Hybrid Picture this... You're joining a business at the start of something new. A completely greenfield project, the freedom to make key technical decisions and the opportunity to build a platform from the ground up.

We're looking for a hands-on technical leader to take ownership of the architecture, lead a team of engineers and help shape how modern software is built using AI. What's on offer? Build a brand-new platform without the constraints of legacy systems.

Own architectural decisions and technical direction. Lead and mentor a team of backend and data engineers. Work with modern AI coding tools such as Claude Code, Cursor and GitHub Copilot. Tackle interesting challenges around large-scale data, distributed systems and real-time processing.

Who are we looking for? This could suit an established Principal or Staff Engineer, Technical Architect, or an experienced Lead/Senior Developer ready to step up. You'll ideally bring: Strong C#, .NET and Azure experience.

Experience designing scalable, data-intensive systems. Knowledge of microservices, distributed systems and event-driven architecture. Exposure to Python and data engineering. Experience leading technical decisions and using AI coding agents.

Experience with AWS, streaming data or machine learning would be a bonus. Are you a Senior, Lead or Principal Engineer looking for your next challenge? I'd be keen to have a conversation
