We're looking for a Lead Mobile Engineer React Native to drive and scale the development of the Orca App. This is a hybrid role that blends hands-on engineering with technical and team leadership. Your success will come from architecting long-term solutions that endure, raising the bar for the team, and shaping an engineering culture centered on delivering high customer value.

What You'll Do

• Lead the mobile App team-own the app architecture, drive technical decisions, and ensure high-quality delivery.
• Mentor, support, and help grow a small team of talented React Native engineers.
• Balance hands-on contributions with coaching and technical guidance.
• Partner closely with Product, Design, and Backend to shape roadmap and execution.
• Build robust, performant, and reliable features like sail routing, weather layers, real-time navigation, and offline maps.
• Champion best practices in code quality, testing, performance, and release management.
• Contribute to hiring and onboarding as we scale the engineering team.

What You Bring

Technical Skills

• 7+ years of mobile development, including 5+ years building production React Native apps.
• Strong foundation in computer science principles and software architecture design.
• Expert-level knowledge of TypeScript, React, and modern front-end patterns.
• Hands-on experience upgrading React Native versions and managing related code migrations.
• Strong capability in profiling and optimization for performance and battery usage.
• Experience with app instrumentation for monitoring, analytics, and observability.
• Proficiency with native development in Java/Kotlin and Objective-C/Swift, including integration of native modules and working knowledge of TurboModules/JSI.
• Experience implementing and maintaining CI / CD pipelines for mobile applications.

Leadership & Execution

• Proven experience leading small engineering teams or technical projects.
• Strong systems thinker who balances short-term velocity with long-term maintainability.
• Clear communicator who can align teams, clarify tradeoffs, and push through ambiguity.
• Passion for product and UX-thinks like a customer and codes like an owner.
