Senior React Native Developer

We are seeking a Senior React Native Engineer to own the architecture, performance, and scaling of our core mobile products. In this role, you will build complex cross-platform features, author native modules when abstractions fall short, and drive app performance down to the frame rate level for millions of active users. You will work on-site alongside a focused engineering team, directly influencing our technical roadmap and mobile standards.

Responsibilities:

• Architect and maintain production React Native applications targeting both iOS and Android.
• Write custom native bridges and modules in Swift, Objective-C, Kotlin, or Java to interface with OS-level APIs.
• Diagnose and resolve performance bottlenecks, memory leaks, and render-cycle inefficiencies.
• Design continuous integration and deployment pipelines to streamline App Store and Google Play releases.
• Establish frontend testing strategies, including unit, integration, and end-to-end automation.
• Guide architectural decisions and conduct high-rigor code reviews for the mobile engineering team.

Requirements:

• 7 to 10 years of total software engineering experience, with a heavy concentration in mobile development.
• At least 4 years of hands-on experience building and deploying complex React Native apps at scale.
• Proven ability to write native code for iOS (Swift/Objective-C) and Android (Kotlin/Java).
• Deep understanding of the React Native render pipeline, JSI, thread management, and state architecture.
• Experience managing automated release pipelines using tools like Fastlane, Bitrise, or App Center.
• Full-time availability to work on-site at our headquarters.

Nice-to-Haves:

• Experience migrating legacy fully native applications to React Native.
• Direct involvement in open-source React Native libraries or tooling.
