Expedia Group is hiring an User Experience Engineer III Front End Web

Expedia Group is hiring a User Experience Engineer III to join the Loyalty Experience Team. You will lead the design and implementation of complex, user-facing systems and experiences that are performant, reliable, and scalable. This role translates high-level product and UX requirements into robust technical solutions and drives end-to-end ownership from design to production.

What You'll Do

• Lead the design and implementation of complex user-facing systems and experiences that are performant, reliable, and scalable across web and/or native platforms.
• Translate product and UX requirements into robust technical solutions, defining component architectures, client-side state management strategies, and clean integrations with backend services.
• Drive end-to-end ownership of major features and projects, from design and implementation through production deployment, monitoring, and continuous improvement.
• Apply strong software engineering fundamentals—including system design, data structures, and design patterns—to produce clean, modular, maintainable code.
• Design software that is highly testable and observable, implementing effective monitoring, logging, and debugging strategies.
• Mentor and guide junior engineers by sharing technical expertise, participating in code reviews, and promoting engineering best practices.
• Collaborate with cross-functional partners including product, design, data, and platform engineering teams to deliver high-impact user experiences.
• Evaluate and select appropriate technologies, frameworks, and programming languages to solve technical challenges.
• Build reusable, modular components and shared frameworks that improve consistency and accelerate development across multiple teams.
• Proactively identify performance bottlenecks, operational inefficiencies, and architectural limitations, and drive improvements.
• Use both qualitative customer insights and quantitative data to guide technical decisions and continuously improve user experiences.
• Partner with design and research teams to deeply understand customer needs, motivations, and challenges.
• Contribute to operational excellence by investigating production issues, leading root cause analyses (RCAs), and implementing long-term improvements.
• Actively participate in engineering communities of practice, sharing knowledge and continuously building new technical capabilities.
• Explore and integrate emerging technologies, including AI-assisted capabilities, where appropriate to enhance user experiences, personalization, and product innovation.

What We're Looking For

• Bachelor’s or Master’s degree in Computer Science, Engineering, Human-Computer Interaction, or a related technical field, or equivalent practical experience.
• 5+ years of professional software engineering experience with a Bachelor’s degree, or 3+ years with a Master’s degree.
• Proven experience building and operating production-grade software systems, including debugging, monitoring, and maintaining applications at scale.
• Experience developing software using multiple programming languages and selecting the appropriate language or technology for specific use cases.
• Strong understanding of system design principles, including modular architecture, API integration, and the interaction between applications, databases, and platform infrastructure.
• Demonstrated experience implementing automated testing, monitoring, and debugging practices to ensure software reliability and performance.

Nice to Have

• Experience designing and implementing scalable user experience architectures, including reusable UI frameworks, shared component libraries, or design systems.
• Proven ability to lead technical design and implementation for complex features, influencing engineering decisions across teams or projects.
• Strong expertise in modern UI engineering practices, including component-based architectures and integration with backend services.
• Experience mentoring engineers and contributing to a culture of strong engineering practices through code reviews, design discussions, and technical knowledge sharing.
• Demonstrated ability to evaluate technology trade-offs and make pragmatic decisions that balance speed, quality, and long-term maintainability.
• Experience identifying systemic inefficiencies across codebases or development processes and driving improvements that increase engineering efficiency and system reliability.
• Ability to communicate complex technical concepts clearly to both technical and non-technical stakeholders and influence cross-functional decision making.
• Experience leveraging customer insights, analytics, and research to inform technical decisions and improve product outcomes.
• Familiarity with AI-driven systems, tools, or workflows and an interest in applying AI/ML concepts to user experiences such as personalization, intelligent recommendations, conversational interfaces, or AI-assisted product features.
• Experience collaborating with data science or machine learning teams to integrate AI-powered capabilities into user interfaces while ensuring responsible, transparent, and user-centric experiences.
