About the Role: We're growing our engineering team and looking for a Senior Full Stack Engineer who excels at both front-end and back-end development. In this role, you'll split your focus evenly creating intuitive user experiences and building robust back-end systems. You enjoy working across the stack, ensuring quality and performance in both the client and server sides. If you thrive on seeing projects through from concept to deployment and making an impact at every level, we’d love to connect.

What you’ll do:

  • Design, build, and maintain scalable front-end applications in JavaScript/TypeScript (React)
  • Develop, enhance, and maintain backend services in C# (.NET)
  • Collaborate with designers, product managers, and engineers to deliver cohesive user experiences
  • Play a key role in architectural decisions, ensuring consistency and best practices across the full stack
  • Drive code quality, testing, accessibility, and continuous improvement throughout the software lifecycle
  • Write maintainable, testable code that performs reliably in production
  • Support integration with both RESTful APIs and event-driven microservices

What you’ll bring:

  • 6+ years building production software with substantial experience in both front-end and back-end development (React and .NET)
  • Advanced skills in JavaScript/TypeScript, React (or similar frameworks), and front-end architecture
  • Strong, hands-on experience with backend services using C# and .NET
  • Proficiency working with RESTful APIs and event-driven architectures
  • Hands-on experience with Azure or similar cloud platforms
  • Familiarity with DevOps tooling such as GitHub Actions, TeamCity, or Octopus
  • Passion for intuitive, accessible, and reliable applications across the stack
  • Excellent testing skills and a commitment to high-quality delivery
  • Strong communication and collaboration abilities within cross-functional teams
  • A curious mindset, energized by solving complex challenges in a dynamic environment

Key benefits:

  • Hybrid working: we’re headquartered in North Sydney with state-based workplaces and offer a hybrid work policy. Our offices have spaces for collaboration, socialising and focused work.
  • Parental leave: up to 26 weeks paid.
  • Strategy Week: twice a year the whole team comes together to hear the business strategy and product and technology roadmap first-hand, with fortnightly all-company business updates in between.
  • Flat structure: everyone can learn from each other and senior leaders across the business.
  • Wellbeing: benefits supporting your physical, psychological and financial wellbeing, from a day off on your birthday to end of trip facilities.
