About the team:
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 Recs 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:
•
Build, enhance, and maintain Android applications using Kotlin, applying solid understanding of Android platform capabilities, UI components, and mobile design patterns to deliver high-quality customer experiences across Expedia Group brands.
•
Design and implement clean, testable, and maintainable low-level designs (LLD), APIs, and data models for mobile features that integrate reliably with backend services and shared platforms.
•
Apply software engineering best practices in coding, testing (including unit and UI tests), code reviews, and continuous integration to ensure high reliability, performance, and security of Android applications.
•
Collaborate with product managers, designers, and other engineers across teams to break down requirements, refine technical solutions, and deliver features iteratively while maintaining a strong customer focus.
•
Safely integrate and operate AI/ML‑enabled solutions that improve outcomes, including personalization, recommendations, or automated insights, while ensuring responsible use of data and adherence to privacy and security standards.
•
Demonstrate familiarity with AI-driven systems, tools, or workflows and applying AI/ML concepts to real world products, and adapt your Android engineering skills to work across multiple domains, services, or shared mobile components as needed.
Minimum Qualifications:
•
Bachelor’s degree in Computer Science, Engineering, or a related technical field, or equivalent practical experience in professional software development.
•
Experience building and shipping Android applications using Kotlin in a production environment, including ownership of features or services within a larger mobile application.
•
Proven ability to design and implement mobile low-level designs, APIs, and data models, and to work effectively with service-oriented or microservices-based backends.
•
Demonstrated proficiency with core Android development tools and practices, including version control, testing frameworks, debugging, performance optimization, and continuous integration/continuous delivery pipelines.
Preferred Qualifications:
•
Experience using Jetpack libraries and modern Android tooling (e.g., Jetpack Compose, Coroutines/Flows, Android Studio, Gradle) to build scalable, testable architectures.
•
Awareness of performance and reliability considerations on mobile (app start, scrolling performance, memory, battery) and experience using profiling/monitoring tools to diagnose and fix issues.
•
Comfortable defining and implementing test strategies (unit, UI, snapshot, and integration tests)
•
Awareness of accessibility and inclusive design basics on Android (e.g., Talkback, touch targets, contrast) and a desire to improve the accessibility of native experiences.
•
Experience working in cross functional Agile teams, collaborating with Product, Design, and other engineers, and communicating clearly about progress, risks, and trade-offs.
•
Familiarity with AI driven systems, tools, or workflows and applying AI/ML concepts to real world products, including thoughtful use of AI powered coding and productivity tools
