About the role:

We're looking for a Full Stack Software Engineer who enjoys building things end to end, from polished interfaces to the backend services that power them. This role can flex to suit you: whether you're a true 50/50 full stack engineer or someone who leans more front-end, we're interested in strong engineers who care about the whole picture.

What you'll do:

• Design, build, and maintain modern web applications across JavaScript/TypeScript (React) and C# (.NET)
• Support and enhance backend services to keep integrations solid and systems reliable
• Partner with designers and product to take ideas from concept to something users love
• Contribute to architectural discussions across the stack, with a focus on maintainability and scale
• Follow engineering best practices around code quality, accessibility, and continuous improvement
• Stay curious about emerging technologies and share what you're learning with the team
• Write high-quality, testable code that holds up in production

• 3+ years building production software in full stack roles
• Proficiency in JavaScript/TypeScript and solid React experience, plus working knowledge of C# and .NET
• Experience integrating with RESTful APIs and event-driven microservices
• Familiarity with DevOps tooling like GitHub Actions, TeamCity, or Octopus
• Azure or cloud experience is a bonus, not a dealbreaker
• A genuine care for building interfaces that are intuitive, responsive, and accessible
• Strong testing instincts and a commitment to reliable delivery
• Someone who communicates well, collaborates naturally, and enjoys cross-functional work
• Curious by nature and energised by learning in a fast-moving environment

• Collaborative teams – a flat structure means everyone can learn from colleagues and senior leaders around the business.
• Be involved – come together with all of your colleagues every 100 days to share the product and technology roadmap and business strategy.
• Flexible working environment – we’re headquartered in North Sydney with state-based workplaces and offer a flexible work policy.
• Family support – industry leading 26 weeks paid parental leave.
• Purpose built spaces within our office – designed for collaboration, brainstorming, socialising, and focused work.
• Range of benefits supporting your physical, psychological and financial wellbeing. From a day off on your birthday to excellent end of trip facilities.
