Bankjoy is a Y Combinator and Bessemer Venture Partner-backed fintech startup transforming how community banks and credit unions operate. The company provides modern digital banking products including mobile banking, online banking, account opening, loan origination, and conversational AI.
As Android Tech Lead, you will own the technical direction, architecture, and delivery of Bankjoy's Android banking platform while managing a team of three Android engineers. This is a hands-on leadership role where you will write production code daily, drive architectural decisions, and ensure the Android product meets the reliability, security, and performance standards that financial institutions and their members depend on.
You will lead technical strategy and architecture, defining the Android roadmap and enforcing engineering standards across the team. You'll drive adoption of modern Android practices including Jetpack Compose, MVVM/Clean Architecture, coroutines, and dependency injection. You'll own delivery across digital banking value streams, breaking down complex initiatives into executable tasks with clear dependencies and timelines.
On the hands-on side, you'll contribute directly to feature development, code reviews, debugging, and performance optimization while maintaining meaningful individual coding contributions. You'll manage three Android engineers through regular 1:1s, performance feedback, and mentoring on Android best practices and fintech domain knowledge. You'll collaborate cross-functionally with Product Management, iOS, QA, backend engineering, and DevOps to deliver a seamless mobile banking experience.
You'll also participate in the on-call rotation for production support, respond to urgent issues impacting clients, and ensure Android implementations meet financial services compliance requirements while applying mobile security best practices like certificate pinning, secure storage, and biometric authentication.
