Senior Frontend Developer

About the job

About the Role : We are seeking a highly skilled Senior Frontend Developer to lead the engineering of our consumer-facing mobile application. We are looking for a builder who understands that React Native is more than just JavaScript—someone who can dive deep into the native layer to deliver a flawless, high-performance experience for our users. You will be responsible for architecting the app, optimizing performance to the millisecond, and bridging the gap between React Native and native Android/iOS platforms. Key Responsibilities • Architect High-Scale B2C Apps: Design, build, and maintain a robust, scalable React Native application that serves a growing B2C user base. • Performance Engineering: Take full ownership of app performance. Proactively profile the app to eliminate frame drops, reduce app size, optimize start-up time, and manage memory/battery usage efficiently. • Native Module Development: Write and maintain custom native modules for Android (Java/Kotlin) and iOS (Swift/Objective-C) to handle complex functionalities that standard libraries cannot support. • Complex UI Implementation: Collaborate with designers to implement smooth and complex gesture-based interactions. • Release Management: Manage the entire mobile release cycle, including CI/CD pipelines, certificate management, and submissions to the Google Play Store and Apple App Store. • Technical Leadership: Mentor junior engineers, conduct code reviews, and drive technical decision-making to ensure code quality and maintainability. Required Skills & Qualifications • Experience: Minimum 6 years of software development experience, with at least 4 years focused on mobile application development. • React Native Mastery: Expert-level knowledge of React Native, including the Bridge, JSI, and the New Architecture. • Native Proficiency (Critical): Strong hands-on experience writing native code for Android (Java/Kotlin) and iOS (Swift/Objective-C). You should be comfortable debugging native crashes and writing bridges. • Performance Tooling: Deep experience with profiling tools such as Flipper, Xcode Instruments, and Android Studio Profiler. • B2C Experience: Proven track record of shipping and maintaining high-traffic B2C applications. • State Management: Proficiency with modern state management (Redux Toolkit, MobX, or Zustand).
