Expedia Group is hiring an User Experience Engineer III

Expedia Group is hiring a User Experience Engineer III to lead the evolution of our search and recommendations experience from concept through production. You will sit at the intersection of design, product, and engineering, driving technical leadership and quality for our high-traffic, multi-brand platform.

What You'll Do

• Lead the design, prototyping, and implementation of high-quality user experiences for search entry, results, and recommendations surfaces across all Expedia Group brands.
• Drive end-to-end technical ownership of complex UX features from requirements gathering and system design through to production delivery and operational stability.
• Build, evolve, and advocate for reusable UI libraries, design-system-aligned components, and shared frontend tooling that powers multiple product teams and brands at scale.
• Champion a data-driven approach by instrumenting UX-related signals and translating A/B test results into actionable product and engineering improvements.
• Collaborate closely with product managers, UX designers, backend engineers, and platform teams to translate requirements into elegant, performant frontend solutions.
• Define and uphold engineering excellence standards including cross-browser behavior, accessibility compliance, CI/CD practices, automated testing, and monitoring.
• Safely integrate and operate AI/ML-enabled solutions within the UX engineering workflow, applying them in a controlled, observable, and measurable way.
• Mentor and support junior and mid-level engineers through code reviews, technical design discussions, and knowledge sharing.

What We're Looking For

• Bachelor's degree in Computer Science or a related technical field; or equivalent related professional experience.
• 5+ years of relevant professional experience as a UX Engineer, Frontend Engineer, or similar role building and owning production web experiences at scale.
• Proficiency with modern web technologies (React, Node.js, JavaScript/TypeScript, HTML, CSS, component-based frameworks).
• Proven ability to design and implement robust, maintainable UI system architectures, including API design and data modeling for frontend integrations.
• Experience leading end-to-end delivery of complex user-facing features in cross-functional product teams with accountability for quality, performance, and stability.
• Track record of applying qualitative and quantitative data including experimentation, A/B testing, and UX performance metrics to drive design and implementation decisions.
• Demonstrated ability to contribute to or evolve shared component libraries, design systems, or multi-tenant UI platforms used by multiple product teams or brands.
• Enthusiasm for responsible use of AI-powered tools to accelerate delivery, with strong engineering judgment to review, refine, and validate AI-generated outputs.
• Commitment to ethical AI use, including data privacy, security considerations, and avoiding over-reliance on AI-generated outputs without validation and testing.

Nice to Have

• Experience designing and leading the evolution of shared UX platforms, design systems, or multi-tenant component libraries used at significant scale across multiple brands or product surfaces.
• Proven technical leadership in cross-functional squads: driving architecture discussions, mentoring peers, and influencing technical strategy for search, discovery, or growth-oriented frontend experiences.
• Track record of owning and improving frontend performance, accessibility, reliability, and operational excellence for high-traffic web properties.
• Hands-on experience safely integrating and operating AI/ML-enabled solutions to improve UX outcomes while maintaining control, observability, and user trust.
• Experience applying LLMs or predictive models to generate, adapt, or personalize search and recommendation experiences in a measurable and responsible way.
• Familiarity with search UX patterns, typeahead/autocomplete systems, recommendation surfaces, or similar discovery-focused experiences in a high-traffic consumer product context.
