- 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.

- 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.
