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
