We’re building a more open world. Join us.

Introduction to team

Private Label Solutions (PLS) is the B2B arm of Expedia Group. We open up our supply and innovative technology to businesses looking to take on the world of travel. These businesses, sometimes referred to as our ‘demand partners’, include global financial institutions (e.g. AMEX), corporate managed travel, offline travel agents (e.g. Flight Centre), global travel suppliers (e.g. Delta) and many more.

We’re looking for a Full-Stack Software Engineer (Front-End Focus) to join our Partner Reporting and Data Distribution team. This team builds data-driven experiences for Expedia’s B2B partners — from analytics dashboards and reporting APIs to internal tools that help partners understand and grow their travel business.

The ideal candidate is a front-end-leaning full-stack developer who’s passionate about building intuitive, performant user interfaces, enjoys solving complex data-integration challenges, and can collaborate across engineering, product, and design.

What you\'ll do:

• Design, build, and maintain front-end applications and partner-facing tools using React, TypeScript, Node, and modern JavaScript frameworks.
• Collaborate with backend engineers to define and integrate APIs, ensuring end-to-end functionality from data ingestion to UI visualization.
• Develop reusable UI components and contribute to shared design systems to ensure consistency across partner platforms.
• Write clean, maintainable, and modular code that follows solid engineering and accessibility principles.
• Contribute to backend services (JVM stack) and participate in code reviews to maintain high standards across the stack.
• Monitor and optimize front-end performance, ensuring fast load times and a smooth user experience for data-intensive views.
• Partner closely with product managers and designers to translate requirements into practical, scalable solutions.
• Participate in Agile development ceremonies, team planning, and release cycles to deliver high-impact features.
• Drive improvements in developer experience, CI/CD workflows, and front-end testing reliability.

Qualifications and experience

• 5+ years of professional software development experience with a focus on front-end or full-stack work.
• Hands-on experience with React, TypeScript, JavaScript (ES6+), Node.js, and front-end tooling.
• Good understanding of modern API design, REST or GraphQL, and how front-end and backend systems interact.
• Familiarity with cloud environments (AWS) and CI/CD pipelines.
• Exposure to backend development (e.g., Java, Python, or Kotlin) and ability to debug across the stack.
• Strong sense of ownership and attention to detail, with the ability to balance product speed and code quality.
• Collaborative mindset — able to work effectively with designers, PMs, and data engineers to ship complete features.

Why Join PLS

• Work on high-visibility partner-facing platforms used by some of the world’s largest financial and travel brands.
• Tackle interesting challenges that combine data, UX, and B2B scale.
• Join a collaborative, cross-functional team that values curiosity, craftsmanship, and measurable impact.
• Grow your career through Expedia’s global engineering community, with opportunities to learn, lead, and innovate across the travel ecosystem.
