Essentials to Succeed

• 7+ years of experience building consumer-facing platforms or distributed backend systems.
• Travel / OTA experience strongly preferred. Ideal candidates have prior experience working within the travel or OTA ecosystem - such as flight metasearch, hotel aggregation, activity marketplaces, travel content platforms, or GDS/LCC/API integrations - and understand the complexities of pricing, availability, and supplier systems.
• Experience with flight or hotel domains is a strong advantage: availability, fare rules, rates & inventory, ranking/relevance, caching strategy, or booking orchestration.
• Hands-on experience working with Node.js (preferred) or other backend technologies.
• Experience deploying applications into cloud environments (AWS highly desirable).
• Strong understanding of API design, microservices, and event-driven architecture.
• Ability to thrive in a fast-paced, complex technical environment with high ambiguity.
• Strong communication skills and ability to collaborate across engineering, product, and third-party partners.
• Demonstrated use of Generative AI tools (e.g. ChatGPT, Cursor, Claude) to develop new or improve workflows, enhance productivity, and drive efficiency at scale
• Bachelor's degree in Computer Science, Software Engineering, Information Systems, or a related technical field
