We are a professional, dynamic, multicultural team in rapid international growth, seeking new partners to help us create the best and most forward-thinking travel company of our generation. What are we proposing? We are looking for a Senior Back-end Software Engineer who is first and foremost a problem solver. Someone who uses engineering as a toolbox to solve real customer and business problems. This role sits within our Trip Management System domain, the team that empowers our travel specialists to design extraordinary journeys at scale. We build the systems that transform destinations, itineraries, flights, hotels and pricing strategies into structured, sellable travel products. By enabling seamless product configuration and ensuring accuracy, flexibility, and scalability, we directly impact revenue, operational excellence, and the quality of the experiences we bring to our customers. Technology choices matter, but impact matters more. You'll work across PHP, Node.js and modern AI tooling, choosing the right approach for each problem rather than being constrained by a single stack. Why Join us: Real, meaningful problems that directly impact customer experience. Freedom to choose the right tool for the problem, including AI. A team that values initiative, ownership, and impact over titles and silos. Scale-up challenges with room to influence architecture, product, and ways of working.

Platform & Operational Excellence Build internal platforms and tools that empower Product, Finance, and Operations teams to work autonomously and efficiently.

Working knowledge of CI/CD pipelines and version control best practices using Git (GitHub Actions or similar). Strong emphasis on testing (unit, integration) and commitment to code quality, scalability, and maintainability. Familiarity with observability practices - including logging, monitoring, and tracing - to ensure visibility and reliability across distributed services. Excellent collaboration and communication skills to work effectively within cross-functional teams. Backend: PHP.
