We are a high-performing team looking for an equally ambitious and driven teammate. The right candidate for this role has a deep understanding of the entire mobile development lifecycle, including design, native development, and deployment, as well as an appreciation for back-end integration. You have a keen eye for design, mobile user experience, and performance. You are able to communicate effectively with other team members and solve complex problems. If you're looking to have a massive impact in a high-growth startup in one of the most exciting markets in decades you will find this role challenging and rewarding in equal measure.

    • Design, develop, and maintain high-quality native applications for iOS and Android.
    • Ensure the best possible performance, quality, and responsiveness of the applications.
    • Collaborate with product managers, designers, and other engineers to define, design, and ship new features.
    • Troubleshoot, debug, and upgrade existing mobile applications.
    • Implement robust and secure communication with back-end services (APIs).
    • Assist with defining and implementing mobile CI/CD pipelines and deployment processes.
    • Inspire the overall company for product excellence through your work as a thought leader and mentor.

    Requirements

    • 5+ years of experience in native mobile development, preferably in the fintech space.
    • Deep professional experience with native iOS development (Swift or Objective-C) and native Android development (Kotlin or Java).
    • Proficiency with mobile state management, threading, and architectural patterns (e.g., MVVM, MVI, Clean Architecture).
    • Solid understanding of mobile security best practices, performance optimization, and memory management.
    • Experience consuming RESTful APIs and working with asynchronous programming.
    • Excellent verbal and written communication skills.
    • Comfort with ambiguity; the ability to independently layout and test clear hypotheses, and solve problems without well-defined direction.

    Preferred

    • Bachelors in computer science or equivalent experience.
    • Experience at a banking-as-a-service, brokerage-as-a-service, or payment-as-a-service business.
    • Library development experience
    • Experience with digital assets preferred, but not required.
    • Familiarity with cross-platform frameworks (e.g., React Native, Flutter) is a plus, but the primary focus is native.
    • Experience with mobile testing frameworks (unit, integration, UI testing).
