They’re a real Australian success story, a fast-growing SaaS scale-up on a mission to take the stress out of paying bills - and they’re already changing lives across Australia and the US.

This is more than just fintech - it’s real-world impact. They’re looking for someone who’s passionate about building intuitive products that genuinely make life easier. You’ll have the chance to move fast, shape what the future looks like, and see your work directly fuel growth and help real people, every single day.

  • Take ownership of technical projects, manage epics, maintain momentum, and clear blockers.
  • Write clean, testable, maintainable code with scalability and performance in mind.

We're looking for:

  • Strong Python and Django skills and understanding of OOP models.
  • Solid experience with ReactJS and TypeScript.
  • Knowledge of Git and CI/CD pipelines.

  • Passion for building innovative solutions with end users in mind.
  • 5+ years of experience in mobile or web development.
  • Collaborative mindset and ability to communicate technical ideas effectively.


It's a bonus if you have:

  • Experience with Django, React Native, or other mobile frameworks.
  • Knowledge of iOS/Android development fundamentals.
  • Experience with Infrastructure as Code (Terraform).
  • Testing experience with Python Unittest, Jest, or React Testing Library.
