Qualifications

• 5+ years of software engineering experience, including time leading a team or owning a major surface while staying hands-on.
• Rock solid Kotlin, Kotlin Coroutines, Kotlin Flow, Dagger 2, MVVM, Clean Architecture, Background Services, Music Player Service, Android animations, Jetpack Navigation, and JUnit tests.
• Experience shipping and maintaining background audio or other long-running background work.
• Understanding of the importance of tests and how to approach writing them, including what can't be covered by them.
• Something you introduced to a team that stuck after you stopped pushing it, and an honest account of what it cost to get there.
• Some comfort with the unpopular half of the job: asking people to change how they work, and living with the friction that follows.
• A view on which changes need heavy review and which don't, argued from what the system does.
• A track record of building things the rest of your team actually used, not only things that made you faster.
• The ability to describe how your team works with AI agents, not only how you do personally.
• Product design intuition, user empathy, and the drive to push Android UI/UX further than the spec asks for.
• Self-drive to improve the app and codebase beyond what's outlined in the spec.

Responsibilities

• Own major features end to end, working closely with our design team — from the decision through to release.
• Own, maintain, and improve reliability metrics for key features.
• Review pull requests and provide constructive feedback.
• Unblock the team when blockers occur and actively contribute to solutions.
• Promote standardization so multiple versions converge to a single, maintainable approach.
• Keep shared components robust and well-documented for easy handoffs.
• Lead when to change team processes and improve release automation.
• Reduce manual interventions to streamline releases.
• Drive automation to catch issues earlier and shorten QA turnaround.
• Help junior engineers grow by providing learning opportunities and guidance.
