Description du poste

Lead Mobile Engineer

You will spearhead the rebuild of our native mobile application using React Native and AI-powered development tools. This is a key strategic role; you will lay the foundations (architecture, CI/CD pipelines, tooling, and best practices) and then scale the mobile scope well beyond what we deliver today.

Missions

• Lead the full rebuild of our existing native mobile applications using React Native, from scratch
• Define and implement the mobile architecture, ensuring scalability, performance, and maintainability
• Set up the complete CI/CD pipeline for mobile (build, test, distribution, store deployment)
• Leverage AI-powered tools (code generation, assisted testing, copilot-style workflows) to accelerate development and raise quality standards
• Establish mobile engineering best practices: code structure, testing strategy, release management, and monitoring
• Collaborate closely with product managers, designers, backend engineers, and stakeholders to deliver a world-class mobile experience
• Progressively extend the mobile scope beyond the current feature set, bringing more of the DiliTrust platform to mobile users
• Mentor the mobile team as the project scales
• Stay on top of React Native ecosystem evolutions, mobile platform changes, and AI tooling advancements

Your Profile

• 8+ years of professional experience in mobile development
• Proven track record as a React Native expert, with deep knowledge of the ecosystem (navigation, state management, native modules, performance optimization)
• Demonstrated ability to start a mobile project from scratch: bootstrapping, architecture decisions, CI/CD setup, and store deployment
• Experience building and shipping production mobile apps on both iOS and Android
• Hands‑on experience with AI-assisted development tools (Claude Code, Cursor, GitHub Copilot, or similar)

Technical Expertise

• Expert-level proficiency in React Native and TypeScript
• Strong understanding of native mobile platforms (iOS/Android) and bridging when needed
• Solid experience setting up and managing CI/CD pipelines for mobile (Fastlane, Bitrise, GitHub Actions, or equivalent)
• Experience with automated testing strategies for mobile (unit, integration, E2E)
• Familiarity with mobile performance profiling, crash reporting, and monitoring tools
• High standards for code quality, testing, and documentation

Leadership & Collaboration

• Ability to take full ownership of a technical domain and drive decisions autonomously
• Strong communication skills, able to articulate technical trade‑offs to both engineers and non-technical stakeholders
• Experience mentoring developers and establishing engineering practices within a team

Tech Stack

• React Native, TypeScript, iOS, Android, UWP, PHP/TypeScript REST APIs, PostgreSQL/MariaDB, Claude code, Docker, CI/CD, GCP
