JOB OVERVIEW

About Outside Hire
Outside Hire is a growing outsourcing company with over 75 employees, building custom products and solutions for our clients. We're dynamic, fast-paced, and always evolving!

----------

About the Role

We're building a next-generation mobile financial services platform that enables instant money transfers, QR-based payments, bill settlements, and merchant transactions—all from a mobile device. This is a greenfield mobile application with a 20-week timeline to MVP and initial market launch. We're looking for a senior Android engineer who thrives in fast-paced fintech environments and can help us build a production-ready, secure, and scalable mobile wallet from the ground up.
Required Technical Skills

Must-Have Experience
• 8+ years of Android development with production apps in Google Play Store
• 5+ years of Kotlin with demonstrated expertise in modern Android development
• Jetpack Compose for building modern, reactive UIs
• Clean Architecture / MVVM with clear separation of concerns
• Financial/Payment Integration experience (payment gateways, card processing, digital wallets)
• Security-first mindset: Experience with encryption, secure storage, certificate pinning, biometric auth
• Local database management (Room, SQLite) with complex queries and migrations
• RESTful API integration with authentication, error handling, and retry logic
• Git version control with branching strategies and code review practices

Strongly Preferred
• Experience with Coroutines and Flow for asynchronous programming
• Push notification implementation (FCM) with deep linking
• QR code generation and scanning libraries
• Dagger/Hilt dependency injection
• JUnit, Espresso, MockK for comprehensive testing
• Experience building highly regulated applications (fintech, healthcare, government)
• PCI-DSS compliance knowledge and implementation experience
• CI/CD setup with GitHub Actions, Bitrise, or similar
• Experience with A/B testing frameworks and feature flags
• Knowledge of accessibility standards and inclusive design

Big Plus
• Previous experience building mobile wallet, payment, or banking applications
• Integration with card networks (Visa, Mastercard) or payment processors
• Experience with identity verification (IDology, Jumio, Onfido)
• Knowledge of financial regulations and compliance requirements
• Experience with AI coding tools (Claude Code, Cursor, GitHub Copilot, Codeium)
• Backend API experience (Java, .NET, Node.js, or similar) for better API collaboration
• iOS development experience (nice to have for cross-platform perspective)

The Startup DNA We're Looking For

This is not a role for engineers who:
• Need detailed specifications before starting work
• Prefer maintaining existing codebases over building greenfield
• Require close supervision or hand-holding
• Want stable, slow-moving corporate environments
• Are uncomfortable with ambiguity or rapidly changing requirements

This IS a role for engineers who:
• Self-start: You can take a PRD and run with it, asking clarifying questions but not waiting for perfect specs
• Pivot quickly: Requirements will change as we validate with users and regulators
• Think like an owner: You care about the business outcomes, not just writing code
• Move fast with quality: Speed matters, but so does security and reliability in fintech
• Embrace AI tools: You see Claude Code, Cursor, and Copilot as force multipliers, not cheating
• Communicate proactively: You flag risks early, document decisions, and keep stakeholders informed
• Have fintech battle scars: You've dealt with payment failures, fraud attempts, and compliance audits

Why OutsideHire?

• Inclusive Environment: Dynamic work environment that values creativity and collaboration
• Cutting-Edge Projects: Modern, well-architected platform with best-in-class tools
• Impact: Build systems that process real financial transactions
• Modern Stack: Quarkus, Kotlin, AWS, and AI coding assistants
• Competitive Benefits: Competitive salary, remote work, professional development
• Growth Culture: Continuous learning, innovation, and recognition
• Work-Life Balance: Semi-flexible hours, remote-first, sustainable pace
