About the Role:
Are you a versatile and skilled Mobile App Developer looking to take ownership of a core mobile application? We are seeking a proactive individual to manage, maintain, and enhance our company's mobile wallet. This is a key role offering significant autonomy and the chance to shape the future of our mobile presence within a collaborative, agile environment.
You will be responsible for an existing React Native mobile wallet application. We require a developer with deep expertise in React Native and its ecosystem, while also being comfortable navigating and resolving issues within the native iOS and Android layers — particularly concerning plugin integrations and compatibility challenges. The ideal candidate is a problem-solver who can work independently, take full ownership of the application, manage the release process, and drive its technical evolution.
Key Responsibilities:
• Application Ownership: Assume primary responsibility for the entire lifecycle of our mobile wallet application – including maintenance, debugging, performance tuning, security hardening, and new feature development.
• React Native Development: Develop, test, and deploy features using React Native as the primary framework. Maintain and enhance the existing codebase, keeping it aligned with the latest React Native best practices and architecture.
• Native Layer Integration & Troubleshooting: Diagnose and resolve complex issues that bridge the JavaScript layer and the native iOS (Swift/Objective-C) or Android (Kotlin/Java) environments, including native module and third-party plugin challenges.
• Feature Implementation: Collaborate closely with product, design, and backend teams within an Agile/Scrum framework to translate requirements into robust and user-friendly mobile features.
• App Store Management: Manage the entire process of building, signing, and releasing the application to the Apple App Store and Google Play Store, including handling metadata and compliance requirements.
• Code Quality & Standards: Uphold high standards for code quality, readability, testing, and maintainability. Implement and champion React Native development best practices.
• Technical Strategy: Contribute actively to technical discussions and decisions regarding the application's architecture, tooling, and future framework evolution.
• Collaboration & Communication: Clearly articulate technical concepts, progress, and challenges to both technical and non-technical stakeholders, participating effectively in Scrum events (Daily Scrum, Sprint Planning, Retrospectives etc.).
Core Skills & Experience Required:
• Proven Mobile Development Experience: Demonstrable track record (typically 5+ years) building, deploying, and iterating on mobile applications available on app stores.
• React Native Expertise: Deep, hands-on experience with React Native as a primary development framework, including strong knowledge of its architecture, ecosystem, and tooling.
• Strong JavaScript & TypeScript Proficiency: Deep understanding of modern JavaScript (ES6+) and its ecosystem (npm/yarn, build tools). TypeScript experience is required.
• Native Bridge Proficiency: Solid understanding of how React Native interacts with native layers. Experience debugging and developing native modules or plugins for iOS and/or Android is highly valuable.
• App Store Release Management: Proven experience successfully managing the end-to-end release process for both iOS (App Store Connect) and Android (Google Play Console) applications, including build configurations, signing, and submission procedures.
• Agile/Scrum Experience: Practical experience working effectively as part of an Agile or Scrum development team, participating in Daily Scrum, Sprints, Planning events and Retrospectives.
• API Integration: Proven ability to integrate securely and efficiently with RESTful APIs and manage application state.
• Version Control: Mastery of Git and standard branching/collaboration workflows.
• Problem-Solving & Autonomy: Excellent analytical and debugging skills. Ability to independently research solutions, manage priorities, and take complete ownership of the mobile application.
• Communication: Strong verbal and written communication skills in English.
Desired (Bonus) Skills:
• Experience with mobile application security best practices (e.g., secure storage, certificate pinning).
• Familiarity with state management libraries (e.g., Redux, Zustand, MobX) in a React Native context.
• Experience with automated testing frameworks for mobile (Unit, Integration, E2E — e.g., Jest, Detox).
• Knowledge of CI/CD pipelines for mobile development (e.g., Fastlane, GitLab CI, GitHub Actions). • Familiarity with other cross-platform frameworks.
• Previous experience in the DLT/Blockchain industry.
What We Offer:
• A central role with substantial ownership and the ability to make a direct impact.
• Opportunity to work with modern mobile technologies in an agile setting.
• A dynamic environment that encourages learning and technical growth.
