• Drive technical direction and influence the design, development, testing, and release of mobile applications using modern Kotlin-first approaches

• Champion UI/UX excellence by collaborating closely with product and design to deliver responsive, polished, and accessible user experiences

• Monitor and improve production app health through crash analytics, performance metrics, and real-world usage insights

• Mentor engineers through code reviews, pairing sessions, knowledge sharing, and collaborative design discussions

Experience you'll bring:

• 5+ years of professional Android development experience

• Strong proficiency in Kotlin, Jetpack Compose, Gradle, and dependency injection

• Strong understanding of modern Android architecture patterns and modularization strategies, with the ability to design and maintain scalable, reusable libraries

• Strong experience with RESTful APIs and real-time communication patterns, with sound judgment around API design and contract trade-offs

• Proficiency with unit, integration, and UI testing and advanced debugging practices

• Experience with CI/CD pipelines (GitHub Actions) and managing Play Store releases

• Operate with high trust and ownership, with the ability to communicate effectively with stakeholders and leadership

Preferred Qualifications:

• Owned and shipped one or more apps to the Google Play Store

• Familiarity with iOS ecosystem (UIKit, SwiftUI, Concurrency)

• Experience with Kotlin Multiplatform (KMP) and usability between Android and iOS

• Experience with logging and eventing tools (Sentry, PostHog)

• Familiarity with device wallet integration (Apple, Google, Android Wallets)

• Experience with mobile hardware frameworks (NFC and/or BLE)

• Experience with AI-assisted development tools (Cursor, Claude Code)

What we're looking for:

We’re looking for an engineer who takes pride in their craft and treats code as a reflection of their standards and values. You care deeply about design quality, paying attention to the small details that make an experience feel intuitive and polished. You think beyond implementation by considering scalability, maintainability, and long-term impact on both users and the team.

You enjoy working in environments with high trust and ownership, where ambiguity is expected and creative problem-solving is encouraged. You stay open-minded about how great software gets built and are eager to explore new tools, approaches, and ways of working that improve both developer experience and product quality. You’re motivated by meaningful constraints, energized by building from the ground up, and excited to help define patterns and practices that will shape the platform for years to come. You bring positive energy to your work, raise the bar through collaboration and mentorship, and push yourself and those around you to do their best work.
