Mobile Engineer II, Android

About the Team

We are building a cutting‑edge platform using the latest technologies to deliver a best‑in‑class shopping experience for travelers and partners across Expedia Group brands. Your work will involve estimating engineering efforts, designing changes, implementing and testing them, pushing to live, and triaging production issues.

Responsibilities

• Build, enhance, and maintain Android applications using Kotlin, applying a 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 apply AI/ML concepts to real‑world products, and adapt 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.
