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.

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.
Write and debug native iOS and Android code when required to solve performance or platform-specific problems.

Quality & Reliability

Develop and maintain comprehensive test cases to ensure application quality and reliability.
Debug complex production and development issues across the mobile stack.
Establish practices that improve application stability, performance, and release quality.
Participate in code reviews and provide thoughtful feedback on architecture, implementation, performance, and maintainability.

Cross-Functional Collaboration

Partner with Product, Design, Backend, and other engineering teams to define and implement scalable mobile solutions.
Translate product and customer requirements into robust technical designs and implementation plans.
Collaborate across teams to identify technical dependencies, trade-offs, and opportunities for improving the overall customer experience.
Communicate technical decisions and complex mobile engineering concepts clearly to both technical and non-technical stakeholders.

Technical Leadership & Mentorship

Mentor junior and mid-level engineers and help raise the technical bar across the mobile team.
Promote clean coding practices, performance optimization, testing, and engineering excellence.
Contribute to technical discussions, architecture decisions, and long-term mobile engineering strategy.
Stay current with developments in React Native, mobile platforms, and modern application performance techniques.
