About The Position

Our Technology Team partners with teams across Expedia Group to create innovative products, services, and tools to deliver high-quality experiences for travelers, partners, and our employees. A singular technology platform powered by data and machine learning provides secure, differentiated, and personalized experiences that drive loyalty and traveler satisfaction. This User Experience Engineer II role sits within Expedia Group’s Book-to-Trip organization, in the Post-Booking Servicing area, which owns the experiences travelers use after they book, including managing cancellations, changes, refunds, and other servicing actions across brands. The team’s mission is to make it simple and stress-free for travelers to manage their trips on their own, reducing the need to contact support while improving satisfaction and loyalty. This is a small, Austin-based engineering team that builds modern web and native mobile experiences, with web as the immediate priority. The team is cross-functional (back-end, full-stack, and front-end engineers) and this role is dedicated to front-end/UI engineering: building high-quality, performant interfaces using React and EG’s design system components (EGDS) in close partnership with UX and Product. A major current focus is evolving our post-booking flows into AI-powered servicing experiences that blend help center, virtual agent, and in-product tools into a coherent trip companion for travelers. As part of the broader Trips and Post-Booking ecosystem, this team’s work directly contributes to strategic goals like increasing traveler self-service, strengthening reliability and speed of our trip surfaces, and building a more contextual, personalized hub for managing booked trips.
