Are you excited to build new technologies that will be instrumental in bringing Expedia Group's evolving brand to life by delivering Native App experiences for millions of users? Come build the future of travel with us! Software Engineers at Expedia Group develop solutions and products that touch millions of people every day around the globe. Our engineers seek some of the most sophisticated problems in the world of travel across various brands - Expedia, Orbitz, Car Rentals, Vrbo, Hotels.com, Travelocity, eBookers and others. We are looking for strong technical talent as well as a keen desire to deeply understand our products and services to push our technology forward with respect to functionality, performance, reliability, and scalability.  

Our team in Search and Recommendations Experience is looking for curious, empathetic, and creative problem solvers with a growth mindset. We are a team of travel-loving makers, building a cutting-edge platform using latest technologies. You will be responsible for building a best-in-class shopping experience for our travellers and partners.  

As a member of the team, you'll estimate engineering efforts, design your changes, implement and test your changes, push to live, and triage production issues. You need to be collaborative, and curious as we build new experiences and improve existing frameworks powering the world's largest travel mobile apps at a scale only a few companies can match.  

In this role, you will: 

• Design, build, and maintain Android features for lodging search and shopping across Expedia Group brands, focusing on usability, performance, and reliability. 

• Collaborate with product, design, backend, and data partners to translate requirements into technical solutions, estimates, and delivery plans. 

• Implement clean, testable, and maintainable code using modern Android patterns (e.g., MVVM/MVI, Jetpack libraries, Kotlin coroutines/Flow). 

• Integrate with backend APIs and platform services to power search, filtering, sorting, and personalization in the lodging experience. 

• Instrument features with analytics, logging, and monitoring to support A/B testing, product insights, and rapid iteration. 

• Participate in code reviews, design discussions, and technical decision-making to evolve our mobile architecture and shared frameworks. 

• Contribute to automated testing (unit, integration, and UI tests) and support a robust CI/CD pipeline for frequent, safe releases. 

• Help triage and resolve production issues, performing root-cause analysis and implementing long-term fixes and improvements. 

• Work closely with other mobile engineers across Expedia Group to share best practices, align on standards, and improve developer productivity. 

• Champion a customer-centric and experimentation-driven mindset, using data to validate hypotheses and inform future iterations. 

Minimum Qualifications: 

• Bachelor’s degree in Computer Science, Engineering, or a related technical field, or equivalent practical experience in Android software development. 

• 5+ years of professional experience developing and shipping Android applications using Kotlin, including ownership of features or services from design through production support. 

• Proven experience designing and consuming APIs, working with data models and persistence layers on Android, and applying sound low-level system design practices. 

• Demonstrated ability to take responsibility for components or services within an application domain, including code quality, reliability, observability, and operational support. 

• Solid understanding of core mobile engineering concepts such as concurrency, networking, performance tuning, and test automation for Android applications. 

 
Preferred Qualifications: 

• Experience building and evolving complex Android applications at scale, including modular architectures, clean architecture patterns, and robust system and API designs. 

• Track record of leading technical design for significant Android features or components, making data-informed decisions, and guiding trade-offs around performance, reliability, and usability. 

• Hands-on experience integrating AI- or ML-powered capabilities into mobile apps (for example, personalization, recommendations, or intelligent automation) and safely operating these solutions in production. 

• Familiarity with AI-driven systems, tools, or workflows in the mobile development lifecycle (such as AI-assisted testing, diagnostics, or developer productivity tools) and applying these to improve engineering efficiency. 

• Strong focus on operational excellence, including monitoring, alerting, incident response, and continuous improvement of Android services and features in collaboration with backend and platform teams. 

• Knowledge of accessibility and inclusive design basics on Android (e.g., TalkBack, touch targets, contrast) and a desire to improve the accessibility of native experiences.
