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 Java Engineer to help us build and scale a travel platform relied on by some of Australia's largest corporate operators. This is not a full stack role, it's a deep backend engineering position for someone who genuinely enjoys the hard problems: complex, high availability systems that process high volume travel booking at scale.

You'll be a key technical contributor on capabilities that matter, building the backend systems that give travel consultants and managers one consistent, reliable way of managing trips for our customers, rather than a patchwork of workarounds and exceptions. 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 / Spring Framework), 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 workforce travel platform
Implement & consume RESTful APIs and SOAP/Web Services that integrate with airline GDS systems, internal booking engines, and third‑party workforce platforms
Build robust, fault‑tolerant service components capable of handling high‑volume, time‑critical travel booking workflows

System Reliability & Observability

Ensure the platform maintains high uptime, this is a mission‑critical system for workforce 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 workflow stack
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, 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, and API design

DevOps & Delivery

Champion DevOps practices across the team: CI/CD pipeline ownership, automated testing (unit, integration, contract), 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 and business stakeholders to translate complex travel workflow requirements into clean, maintainable backend logic
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 expertise in Java (Java 11+, ideally Java 17 or 21)
Proficient with AI coding tools (Claude, GitHub Copilot) and able to critically evaluate AI‑generated code in production contexts
Expert‑level knowledge of the Spring ecosystem: Spring Boot, Spring MVC, Spring Data JPA, Spring Security, and Spring Integration
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 (MySQL, PostgreSQL, or Sybase) including complex query optimisation and schema design

Highly Regarded

Experience in travel technology GDS systems (Amadeus, Sabre, Galileo), NDC, PNR management, travel platforms
Background in workforce management, resource scheduling, FIFO logistics
Familiarity with API gateways, service mesh, microservices strategies
Azure cloud experience: App Services, AKS, Service Bus, Application Insights

Tech Stack

Java 17 / 21, Spring Boot, Spring Framework
REST APIs, SOAP / Web Services (WSDL), JSON, XML
Spring MVC, Spring Data JPA, Spring Security, Spring Integration
MySQL, 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, Mockito, integration and contract testing
