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
• 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
