Job Overview

As the most senior individual contributor in mobile, you will lead the development of our mobile app from the ground up. This role goes beyond coding to defining architecture, shaping the technical foundation, and delivering a high performance, user friendly experience at scale.

What You’ll Do

• Lead the design and implementation of our first mobile app, primarily using React Native, while maintaining flexibility to evolve the tech stack as the product matures.
• Drive key architecture decisions-navigation, state management, animations, and performance tuning-to ensure scalability and maintainability.
• Act as the guardian of mobile UX and performance, deciding what should be built in React Native and where native development is the better fit.
• Partner with backend and product teams to deliver seamless, end to end user journeys.
• Establish mobile engineering foundations-coding standards, CI/CD pipelines, testing practices, and observability-from the ground up.
• Mentor future mobile hires, scale the team, and contribute to the hiring process.

Qualifications

• 8-10+ years in mobile engineering, with at least 3 years of production level React Native experience.
• Solid background in iOS or Android native development, capable of extending and maintaining native modules when needed.
• Proven experience building and maintaining mobile apps with significant active user bases.
• Deep understanding of UX, performance bottlenecks, and platform specific edge cases.
• Strong technical judgment, able to balance trade offs, influence direction, and adapt the stack as required.
• Excellent communication skills and experience collaborating with product, design, and backend peers.
• Experience in consumer first industries, ideally with high scale apps (>100K MAUs).
