At Flight Centre Travel Group (FCTG) our purpose is to 'open up the world for those who want to see'. Every day, we give people all around the world the opportunity to experience something amazing – travel!
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
System Reliability & Observability
- Ensure the platform maintains high uptime, this is a mission critical system for travel operations; downtime has direct operational impact
- Instrument services with Datadog, including APM tracing, custom metrics, log correlation, and dashboard creation to provide full observability across the travel booking stack, frontend and backend
- Define and monitor SLOs/SLIs, respond to incidents, and lead post incident reviews to drive continuous reliability improvement
- Proactively identify and resolve performance bottlenecks, memory issues, and degradation patterns before they impact customers
Architecture & Technical Leadership
- Lead technical design for new capabilities, producing clear architecture and API design documentation before implementation
- Conduct rigorous code reviews and hold the team to high standards for API design, exception handling, test coverage, component quality, and service contract quality
- Identify and reduce technical debt, particularly around legacy integration patterns, file based data exchange, and monolithic components
- Mentor and support junior and mid level engineers, particularly on Java best practices, Spring internals, React patterns, and API design
DevOps & Delivery
- Champion DevOps practices across the team: CI/CD pipeline ownership, automated testing (unit, integration, contract, and frontend), and deployment hygiene
- Collaborate with platform and cloud engineering on Azure based infrastructure, ensuring services are containerised, scalable, and maintainable
- Work closely with product managers, designers, and business stakeholders to translate complex travel booking requirements into clean, maintainable full stack solutions
- Participate actively in agile delivery processes, sprint planning, refinement, retrospectives and drive continuous improvement
You'll be perfect for the role if you have:
- 7+ years of professional software engineering experience with deep, hands on expertise across both Java (Java 17+, ideally Java 21) and React, comfortable owning features end to end rather than favouring one side of the stack
- Proficient with AI coding tools (Claude, GitHub Copilot) and able to critically evaluate AI generated code in production contexts
- Expert level knowledge of the Java ecosystem: Spring Boot, Spring Data JPA / Hibernate, Spring Security, and integration frameworks such as Kafka or RabbitMQ
- Expert level experience with React, including hooks, component driven architecture, state management, and building maintainable, well tested frontend applications
- Strong track record designing and building complex REST APIs and Web Services (SOAP/WSDL); including versioning, contract design, and error handling at scale
- Proven ability to instrument and operate production systems using Datadog: APM, dashboards, monitors, log pipelines, and AI powered anomaly detection and forecasting features
- Experience with relational databases (SQL Server, PostgreSQL, or Sybase) including complex query optimisation and schema design
Tech Stack
- Java 17 / 21, Spring Boot, Spring Framework
- React, JavaScript, HTML/CSS
- REST APIs, SOAP / Web Services (WSDL), JSON, XML
- Spring Data JPA / Hibernate, Spring Security, Kafka or RabbitMQ
- SQL Server, Sybase, SQL query optimisation
- Datadog (APM, dashboards, monitors, log pipelines, SLOs)
- Azure (App Services, AKS, Service Bus, Storage)
- GitHub, Azure DevOps, Jenkins, automated CI/CD pipelines
- JUnit / TestNG, Mockito, Jest / React Testing Library, integration and contract testing
