What the job involves
- 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
- 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
- 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
- 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
- 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
- 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
- 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
Our take
Modern consumers expect slick mobile banking apps, but whilst major nationwide banks can easily develop and deploy a sophisticated and secure system for their customers, smaller banks and credit unions often lack the resources to do this. With more than 6000 credit unions serving a hundred million members in the US alone, there’s certainly a strong potential market for such services - which Bankjoy is rising to fulfil.
Bankjoy doesn’t wish to compete with the major banks. Instead it has created a product that is aimed at smaller businesses, primarily credit unions. Its platform enables banks to offer their customers features like mobile banking, online banking, e-statements, online account opening, online loan origination, and conversational AI, all enabling them to better serve their customers.
The business has grown fast, securing more than 63 clients - including the likes of One Detroit Credit Union and UMe Credit Union - and serving over a million members to date. Alongside the 2023 launch of its "Online Account Opening 2.0", which enables financial institutions to quickly and seamlessly onboard new members and clients, Bankjoy won the 2024 Best Digital Banking Platform Award at the Fintech Breakthrough Awards. It's also secured impressive funding to support its continued growth and product innovation.
