Job Summary:

Our Client is seeking an exceptionally skilled and experienced Senior React Native Lead Engineer to serve as the definitive technical authority and architectural owner for their mission-critical Android mobile application within the complex C4I ecosystem. The ideal candidate will possess deep expertise in React Native, profound mastery of the underlying Android native platform (Java/Kotlin), and a proven track record of designing high-reliability, fault-tolerant, and secure systems. This role is responsible for the technical roadmap, architectural governance, custom native module definition, and mentorship of
the entire mobile team, ensuring the application meets rigorous operational standards,
including continuity of functions and zero data loss.

Key Responsibilities:

• Architectural Ownership: Define, lead, and drive the technical roadmap and architectural vision for the mobile application, ensuring scalability, maintainability, and alignment with the overall system architecture.
• Native Bridge Design: Architect and implement complex, high-reliability custom Native Modules, specifically Turbo Native Modules (Java/Kotlin), to facilitate seamless integration with specialized components, proprietary systems (Desktop App), Health SDKs, and Wearable devices.
• Performance Optimization Strategy: Define the comprehensive strategy for performance optimization, profiling both the JavaScript and Android Native UI threads to eliminate rendering bottlenecks and ensure a smooth, instantaneous user experience required for operational use.
• Build & Deployment Oversight: Own the Continuous Integration/Continuous Deployment (CI/CD) pipeline for Android, including optimizing native build configurations (e.g., managing ABIs, implementing caching tools) to maximize developer efficiency and reliable deployment.
• Technical Leadership & Mentorship: Provide high-level technical guidance, conduct rigorous code reviews, and mentor mid-level and junior engineers, acting as a technical multiplier to elevate the team’s overall competence and adherence to quality standards.
• Ecosystem Interoperability: Define the client-server communication contracts, potentially leveraging modern, low-latency protocols like WebSocket, to ensure real-time data flow and robust synchronization across the entire environment.

Qualifications:

• Experience: Minimum of 5+ years of commercial software engineering experience, with 3+ years specifically leading or acting as a principal contributor on complex React Native projects.
• Technical Mastery: Deep, demonstrable expertise in JavaScript and modern React Native architecture (knowledge of Fabric/Turbo Modules concepts highly preferred).
• Android Native Proficiency: Advanced knowledge of Android Native development (Java/Kotlin) and the Android SDK, necessary for designing, debugging, and optimizing custom native interfaces and modules.
• Performance Expertise: Proven experience in complex performance optimization, memory management, and debugging in a resource-constrained mobile environment.
• Security: Strong understanding of mobile security protocols, data encryption (at rest and in transit), code hardening techniques (Hermes, Proguard/R8), and secret management best practices.
• Soft Skills: Excellent verbal and written communication skills, with the ability to articulate complex architectural decisions to technical and non-technical stakeholders.
