Senior Full-Stack Engineer - Sydney (Hybrid)

Build at scale. Own what you ship. Grow fast.

We’re a high-growth, profitable ASX-listed FinTech on a mission to reshape how financial products are delivered. Backed by strong momentum and real market traction, we’re now scaling our engineering teams and looking for Senior Full-Stack Engineers to help drive the next phase.
You’ll be joining a lean, high-performing team where engineers don’t just ship code, they own outcomes end-to-end.
 
Tech & Engineering Culture:

- Backend: C# .NET Core 
- Frontend: React (flexible if you’ve used other frameworks) 
- Architecture: Microservices + Event-Driven systems 
- Practices: TDD, BDD, SOLID principles 
- Cloud & Tooling: AWS, modern DevOps pipelines

We care more about engineering mindset and fundamentals than ticking every box.
 
What You’ll Be Doing
  • Build and enhance customer-facing and critical internal platforms
  • Own systems end-to-end; from design through to production
  • Design and develop scalable microservices & event-driven solutions
  • Tackle complex, real-world engineering challenges
  • Drive technical initiatives and projects (hands-on leadership)
  • Work across a diverse domain: APIs, credit systems, treasury, and more
  • Gain exposure to data platforms, DevOps, and emerging AI initiatives
Why This Role Stands Out
  • Real ownership: You build it, you run it, you improve it
  • High impact: Your work directly influences business outcomes
  • Strong engineering culture: Clean code, best practices, and autonomy
  • Career acceleration: Clear pathway into technical leadership
  • Variety & scale: Complex domain + growing platform = constant challenge
Who This Is Perfect For

You’re a hands-on Senior Engineer who:
  • Loves solving complex, meaningful problems
  • Wants ownership, not just tickets
  • Thrives in a fast-moving, high-trust environment
  • Is ready to step into technical leadership while staying close to code
Let’s Talk!
