• 6+ years experience with web application development, proven understanding of foundational web technologies.

• Direct integration experience with at least one major GDS (Amadeus, Sabre, Travelport): PNR creation, ticketing, queues, pricing, ATPCO, or shopping APIs.

• Practical knowledge of NDC offer/order flows, ancillary handling, and hybrid architectures bridging PNR and Order models.

• Familiarity with travel accounting concepts such as ARC/BSP settlement, e-ticket/EMD lifecycle, and fare/tax computation.

• Experience with:

  • Integrating multi-source travel content (LCCs, rail, hotel wholesalers) and normalizing heterogeneous data.

  • Building or integrating TMC systems, approvals, duty-of-care, traveler profiles, policy engines, or back-office/ERP reconciliation.

  • Containerization and orchestration (Kubernetes or similar) and hybrid cloud environments.

  • Spring/Spring Boot and modern JVM performance practices is a plus.

  • Corporate travel is a plus (travel policies, mid-office QC flows, duty-of-care, traveler profiles, and back-office settlement needs (ARC/BSP, ERP)).
