About the Role

At ShopBack, our engineering teams build scalable and operable platforms serving eCommerce and travel traffic across the region, delivering world‑class product experiences. You will join a diverse and talented team of engineers with strong ambitions to redefine how users discover, compare, and book travel products.

We are now expanding our Travel engineering team and are seeking experienced engineers who have built large‑scale travel or OTA (Online Travel Agency) systems. If you have worked on flight, hotel, or activities search platforms, pricing engines, real‑time availability systems, or GDS integrations, we want to speak with you.

You are someone who is resilient, self‑driven and highly motivated. You want to see the impact of your work making a difference every day. You find passion in the craft and are constantly seeking better ways to solve tough problems.

Your Adventure Ahead

Lead and deliver large‑scale travel platform components such as flight/hotel search, pricing/availability aggregation, booking flows, or content systems.

Contribute to ideation, technical design, implementation, and testing of high‑impact travel product features.

Design and build robust, scalable distributed systems capable of handling real‑time travel inventory and pricing.

Architect clean, well‑structured APIs used by client applications for search, booking, and trip management.

Collaborate closely with Product, Data, and UX teams to shape the future of the ShopBack Travel experience.

Work with external partners (OTAs, GDS, suppliers) to integrate APIs, understand domain constraints, and improve reliability.

Drive engineering best practices, mentor other engineers, and elevate technical standards within the team.

Analyze complex requirements, propose pragmatic solutions, and articulate trade-offs clearly.

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
