Job Description

We're hiring a Staff Full-Stack Software Engineer (.NET & Azure) to join a fast-growing treasury platform giving businesses from SMEs to Fortune 500s real-time control over their liquidity, across traditional and digital assets.

If you've spent 8+ years deep in C#/.NET Core, Azure, and Angular/TypeScript, and you're the person who doesn't just ship features but pushes back when there's a better way to build something - we want to talk to you.


What you'll be doing:

  • Owning full-stack delivery (front-end, server-side, database) on a cloud-native Azure platform
  • Setting technical direction and mentoring engineers around you
  • Leading modernization of complex financial systems, not just maintaining them
  • Working in a you-build-it-you-run-it culture with real ownership, not just tickets


What we're looking for:

  • 8-10+ years hands-on with C#, ASP.NET Core, SQL Server
  • Strong Azure Services + Azure DevOps CI/CD experience
  • Angular/TypeScript, TDD/BDD practice
  • Financial services or capital markets experience a strong plus
  • A track record of staying with teams and seeing hard problems through to closure - not a string of six-month hops


Why apply through us:

  • Fast-moving process - no lengthy interview loop, we manage the vetting upfront
  • We back candidates who challenge the status quo, not just ones who tick boxes
