Role ContextAs a Senior Software Engineer (SDE III), you are a high-impact individual contributor building core capabilities of FLX ONE Cargo. This role is centred on deep hands-on development, technical problem solving, and ownership of meaningful parts of the system.You will work on complex backend and full-stack components, shape implementation patterns through code, and help ensure that services are built in a modular, scalable, and production-ready manner. You influence the team primarily through the quality of your code and technical judgment, not through formal leadership.
What You’ll OwnHands-On Development & Vibe Coding- Design, build, and evolve core FLX ONE Cargo services and APIs using modern enterprise stacks.
- Rapidly prototype, iterate, and refine solutions while maintaining production-grade quality.
- Take ownership of complex or high-impact components within the codebase.
- Actively participate in debugging, optimisation, and production issue resolution.
Technical Excellence & Quality
- Write clean, maintainable, and well-tested code that others can build upon.
- Perform thoughtful code reviews that raise overall code quality and consistency.
- Apply modular design principles to enable independent evolution and future migration paths.
Operational Ownership
- Own the runtime behaviour of the services you build, including reliability and performance.
- Contribute to observability, logging, and alerting to ensure systems are supportable in production.
- Participate in on-call or escalation rotations as appropriate.
Collaboration & Enablement
- Work closely with Tech Leads, Architects, and Product to turn requirements into sound implementations.
- Pair with other engineers to share context, unblock progress, and spread good practices.
- Support early-career engineers through example, feedback, and collaboration.
What You Must Bring
- 5+ years of hands-on software engineering experience building production systems.
- Strong proficiency in backend or full-stack development using modern stacks (e.g. .NET, Node.js, Java, or similar).
- Experience building and operating cloud-native services on AWS or equivalent platforms.
- Solid understanding of distributed systems, APIs, and event-driven architectures.
- Strong problem-solving skills and a high sense of ownership for what you build.
Nice to Have
- Experience in airline, cargo, logistics, or other integration-heavy enterprise domains.
- Familiarity with modular architectures and incremental migration approaches.
- Exposure to CI/CD pipelines, automated testing, and infrastructure-as-code.
- Experience using AI-assisted development tools to accelerate coding, testing, or debugging.
Why This Role MattersSenior Software Engineers are the engine room of FLX ONE Cargo. Your ability to move fast, write high-quality code, and take ownership of complex problems directly determines how quickly and safely the platform evolves.
What does the future of the air transport industry look like to you? Whether you’re an industry veteran or someone with experience from other industries, we want to make your ambitions a reality!
