Participate in the evolution of our OpenAPI platform architecture, contributing ideas that help it scale to support new products, partners, and traffic levels.
Own features within your services end-to-end: requirements clarification, technical design, implementation, automated testing, observability, rollout, and production support (with guidance where needed).
Help improve reliability and performance of our APIs by monitoring latency, availability, error rates, and integration success metrics, and acting on what you see.
Collaborate closely with Product and Partner-facing teams to understand partner needs, support integrations, and turn feedback into platform and documentation improvements.
Contribute to common libraries, patterns, and tooling that make it easier for other teams to build on the Indirect Booking Ecosystem.
Participate in code reviews, design discussions, and incident reviews, raising the bar for code quality, observability, and operational excellence over time.
