Lead Android Engineer

Job Description

🌐 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.

What You’ll Do

Technical Leadership & Architecture

• Own the Android technical roadmap — architectural decisions, technology choices, and long-term platform direction

• 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

• Champion clean, testable, well-documented Kotlin code across the Android codebase

Team Leadership & Development

• 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

• Collaborate with backend engineers on API design and integration patterns for mobile banking flows

• 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

Domain & Leadership Experience

• Demonstrated success leading Android development in a fintech, banking, or similarly regulated product environment

• Proven ability to manage and develop engineers through 1:1s, code reviews, and performance feedback

• Experience working in a value stream or squad-based engineering model — cross-functional collaboration with product, design, QA, and backend

• Track record of delivering high-quality Android products on time in fast-moving startup environments

• Strong analytical and problem-solving skills — able to diagnose root causes, assess architectural trade-offs, and make data-informed decisions

Nice to Have

• Experience with digital banking platforms — mobile banking, account opening, loan origination, or payment flows

• Familiarity with credit union or community bank technology environments

• Experience with mobile security implementation in regulated financial services

• Exposure to AI-assisted development tools — Codex, Copilot, Cursor, or equivalent

• Experience migrating Android UI from XML layouts to Jetpack Compose
