Senior Full Stack Engineer - South Bank, QLD

We're looking for a Senior Full Stack Engineer to help us build and scale a travel platform relied on by some of Australia's largest corporate operators. It's a full stack role for someone who genuinely enjoys the hard problems: complex, high availability systems that process high volume travel booking at scale, end to end, from backend services through to the interfaces people rely on every day. 

You'll be a key technical contributor on capabilities that matter, the kind of work that shapes how thousands of travellers experience booking, changing, and managing their trips. You won't be maintaining someone else's legacy code in isolation; you'll be designing and building new capability from the ground up, including change and cancellation support, waitlist management, and deep policy engine integration, then owning it end to end in production. This is a chance to make decisions that stick: the architecture you choose, the standards you set, and the patterns you introduce will shape how the platform evolves for years to come. 

Day to day:

Core Backend Development

• Design, build, and own complex backend services and APIs using Java (Spring Boot), with a strong focus on reliability, performance, and correctness
• Deliver new modules including: change and cancellation processing, waitlist capability, and policy engine integration across the travel platform
• Implement and consume RESTful APIs and SOAP/Web Services that integrate with airline GDS systems, internal booking engines, and third party travel platforms
• Build robust, fault tolerant service components capable of handling high volume, time critical travel booking

Frontend Development

• Design and build responsive, accessible user interfaces in React that give travel bookers and administrators a clear, reliable view into complex processes
• Own end to end feature delivery: from API design through to the React components and state management that consume them
• Work with component libraries and design systems to keep the UI consistent, maintainable, and easy to extend
• Optimise frontend performance (load times, rendering, bundle size) for users working in time critical, high pressure booking scenarios
