Lead Android Engineer

🌐 Who We Are
Bankjoy is a Y Combinator and Bessemer Venture Partner backed FinTech startup. We are changing the way community banks and credit unions do business, enabling them to become tech-driven and digital first. Bankjoy provides modern digital banking products including mobile banking, online banking, online account opening, loan origination, and conversational AI. Our mission is to revolutionize banking tech infrastructure by leading digital transformation at financial institutions — big and small.

The Role
As Android Tech Lead at Bankjoy, you will own the technical direction, architecture, and delivery of our Android banking platform while leading a team of three Android engineers embedded across our digital banking value streams.
This is a hands-on leadership role. You will write production code daily, drive architectural decisions, and ensure our Android product meets the reliability, security, and performance standards that financial institutions and their members depend on. You will work cross-functionally with Product Management, iOS, QA, and backend engineering to deliver a seamless, high-quality mobile banking experience.

Define and enforce Android engineering standards across the team including code quality, testing practices, and release readiness

Lead solution design for new features and major platform initiatives, ensuring scalability, security, and maintainability

Drive adoption of modern Android development practices — Jetpack Compose, MVVM/Clean Architecture, coroutines, and dependency injection

Partner with iOS Tech Lead and backend engineering to ensure consistent cross-platform product behavior and API contract alignment

Execution & Delivery
Own Android delivery across digital banking value streams — planning, estimation, milestone tracking, and risk management

Break down complex initiatives into executable engineering tasks with clear dependencies and timelines

Proactively identify and resolve technical blockers before they impact release schedules

Collaborate with QA to define Android-specific testing strategy — unit, integration, and UI automation using Espresso or equivalent

Participate in the on-call rotation for production support, responding to urgent issues impacting financial institution clients and their members

Hands-On Development
Contribute directly to feature development, code reviews, debugging, and performance optimization within the digital banking value stream

Maintain a meaningful individual coding contribution while balancing technical leadership responsibilities

Directly manage three Android engineers — conducting regular 1:1s, providing performance feedback, and supporting their technical growth

Foster a collaborative, high-trust team environment that emphasizes engineering excellence and continuous learning

Mentor engineers on Android best practices, fintech domain knowledge, and effective cross-functional collaboration

Partner with engineering leadership on hiring, onboarding, and growing Android engineering capability

Cross-Functional Collaboration
Work closely with Product Management and Design to shape feature scope, assess feasibility, and provide accurate effort estimates

Align with QA on automation coverage strategy — supporting the organization's migration to modern mobile testing frameworks

Partner with DevOps on Android build pipelines, release automation, and CI/CD integration

Security & Compliance
Strictly adhere to security protocols when handling customer financial data

Apply knowledge of mobile security best practices — certificate pinning, secure storage, biometric authentication, and session management — in a regulated banking environment

Ensure Android implementations meet applicable financial services compliance requirements
