Engineering Lead Reshopping - Barcelona Or London

Opportunity We're looking for a Technology Lead to own and drive the technical solution behind Reshopping.
Reshopping continuously monitors booked hotel reservations and air itineraries and secures better rates and fares on behalf of some of the world's largest corporate travel programs.
Spotting a better price is the straightforward part.
Acting on it safely, at volume, without a person in the middle and without disrupting the traveler, is the engineering challenge.
That is the system you will design and build.
You will own the architectural blueprint and the end-to-end solution design, oversee the build, and drive the integrations that make it work.
A meaningful share of the engineering capacity sits outside the program, so you will also be the technical counterpart for the teams we depend on — agreeing how the pieces fit rather than assuming that they will.
You will report to the Program Leader, Reshopping, and work across both hotel and air.
Location This role can be based in one of our major offices in Barcelona or London.
Preference for Barcelona.
Key Responsibilities Own the end-to-end solution design for reshopping across hotel and air, spanning the resources within the program and the teams we depend on.
Own and maintain the architectural blueprint, keeping every contributing team building to the same picture, and making trade-offs explicit.
Oversee the build and construction — design reviews, technical quality, and confidence that what is delivered matches what was designed.
Act as the technical counterpart for engineering teams that contribute to reshopping but sit outside the program: agree interfaces and sequencing peer to peer, and escalate to the Program Leader when the question becomes one of priority or funding.
Drive integrations across partner platforms, including hotel and air content sources, mid-office, ticketing, and invoicing.
Design partner integrations so that adding or changing a provider is contained work rather than a rebuild.
Own engineering estimation and sizing, and push back where a requirement is not yet specific enough to size, or where the business rationale is not yet clear.
Design the end-to-end system to scale, including the steps that remain manual.
Establish observability, alerting, and service levels for a system that acts unattended on customer bookings, with staged rollout and kill-switches by market and client.
Evaluate where AI and automation can improve outcomes while maintaining appropriate levels of auditability and deterministic logic.
Champion an AI-assisted software development lifecycle, applying AI across design, build, testing, and review to lift both the pace and the quality of what we deliver.
Drive innovation in how we build — modernizing the technology stack and our ways of working, and making the case for change where the current approach limits what reshopping can become.
Contribute to a safe, inclusive, accessible, and fun work environment where all Flighties feel welcomed, respected, and supported to thrive.
