About the project

We are looking for a Senior Java QA Engineer with strong Java skills to join a team focused on backend application development and testing. The role involves testing RESTful APIs, gRPC services, and backend systems deployed in GCP/GKE.
Our client's multisource capability is an aggregated travel retailing solution designed to unite fragmented content. It merges traditional GDS (ATPCO/EDIFACT) data, low-cost carrier (LCC) flights, and New Distribution Capability (NDC) offers into a single, seamless workflow for travel agencies.
This unified retailing approach operates primarily through the Marketplace project and the Cache-powered Intelligent Shopping system.
Key features include:
  • Unified Workflow: Travel agents can shop, compare, and book across different content sources on a single screen without needing to navigate between disparate airline systems.
  • Pre-generated Caching: Uses a cloud-based data cube to generate offers at sub-second speeds, vastly improving system look-to-book ratios and reducing search times.
  • Next-Generation APIs: Utilizes modular APIs like Flight Shop and Order Management to automate searching, pricing validation, and post-booking servicing (such as exchanges and reshopping) across multiple air sources.
  • By integrating this technology, travel brands and AI-driven applications are able to handle the rising complexity of personalized airline offers at scale.
