Project info:

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"

Responsibilities:

• Design, implement, and maintain automated tests for RESTful and gRPC APIs, with a primary focus on backend validation using an internal Spring Boot–based framework.
• Perform integration testing of backend systems in a cloud environment (GCP).
• Provide support during release cycles, including smoke testing, manual validation.
• Develop and enhance test frameworks using Java.
• Analyze logs, metrics, and errors to identify and troubleshoot issues.
• Collaborate closely with development, SRE, and product teams.
• Participate in CI/CD processes and integrate automated tests into pipelines.
• Mentor junior QA engineers and share knowledge across the team.
• Be open to participating in on-call support rotation

Job requirements:

• Knowledge of CI/CD tools: GitHub, Jenkins/GitHub Actions.
• Experience with containerization tools: Docker, Kubernetes.
• Familiarity with monitoring/logging tools: Prometheus, Stackdriver.
• Basic scripting skills in languages such as Python or Bash, useful for test automation, data preparation and tooling.
• Experience using WireMock or similar tools for mocking external services and simulating API responses in integration tests
