THE ROLE
Software Development Engineer III – Mobile
We’re looking for a Software Development Engineer III – Mobile to join our growing engineering team and help build high-performance mobile experiences for Quince customers. In this role, you will design, develop, and optimize React Native applications that deliver fast, reliable, and seamless experiences at scale.
You will take ownership of complex mobile engineering problems, with a strong focus on performance, scalability, and user experience. You’ll work closely with Product, Design, and Backend teams to build scalable solutions while contributing to the evolution of Quince’s mobile architecture and engineering practices.
This role is ideal for an engineer who is deeply passionate about mobile performance, enjoys solving complex React Native challenges, and is willing to go beyond standard implementations to deliver an exceptional customer experience.
Responsibilities
Mobile Application Development
- Design, develop, and maintain high-performance mobile applications using React Native.
- Build scalable, reusable, and maintainable components following modern mobile engineering best practices.
- Take ownership of complex technical problems across the React Native application stack.
- Evaluate and adopt appropriate libraries, frameworks, and architectural patterns as the mobile platform evolves.
- Contribute to internal libraries and platform capabilities where existing solutions do not adequately address engineering requirements.
Performance & Optimization
- Drive mobile performance improvements across rendering, startup time, memory usage, responsiveness, and application stability.
- Identify and eliminate unnecessary re-renders and inefficient render cycles.
- Optimize large lists and complex UI interactions to deliver smooth experiences across a wide range of devices.
- Analyze application performance and proactively identify bottlenecks before they impact customers.
- Establish and promote performance engineering best practices across the mobile team.
React Native & Native Platform Engineering
- Work deeply with React Native internals and modern React Native architecture.
- Build and optimize solutions using technologies such as FlashList, React Native Reanimated, React Native Gesture Handler, and Expo.
- Investigate complex framework and platform-level issues across iOS and Android.
- Work with TurboModules and native platform capabilities when React Native abstractions are insufficient.
