Lead React Native Developer

Role Summary & Key Responsibilities We are looking for a seasoned Lead React Native Developer to take full ownership of BRT's mobile engineering function. This is a leadership-plus-hands-on role with three interconnected mandates. • New iBMS Mobile Products: Architect and develop new React Native iOS and Android applications for the full suite of iBMS products — from initial discovery and UI/UX collaboration through to App Store and Play Store submission and post-release operations. • Legacy App Migration: Lead the systematic conversion of BRT's existing native iOS (Swift/Objective-C) and Android (Kotlin/Java) applications to a unified React Native codebase, preserving feature parity, design fidelity, and platform-specific user experience expectations. • Team Enablement &Mentorship: Mentor and upskill a team of native iOS and Android developers, guiding their professional transition to React Native development through structured learning pathways, pair programming, code reviews, and internal knowledge-sharing sessions. Required Qualifications & Experience • Minimum 6 years of mobile development experience, with at least 4 years dedicated to React Native in production environments. Minimum 2 years of formal team lead or staff engineer experience with direct mentoring responsibility for mid-senior engineers. • Demonstrable experience leading a team through a significant technology transition (platform migration, framework adoption, or language re-platforming). • Expert-level proficiency in TypeScript; strong understanding of JavaScript runtime behaviour, event loop, and async patterns. • Deep knowledge of React Native internals, proven experience with state management, mastery of React Navigation and complex nested navigation architectures. • Proficiency with react-native-cli, managed and bare workflows; ability to evaluate trade-offs and choose appropriately per project. • Solid understanding of native iOS development (Swift, Objective-C, UIKit, SwiftUI) sufficient to author and debug React Native native modules and bridges. • Solid understanding of native Android development (Kotlin, Java, Jetpack) sufficient to author and debug React Native native modules and bridges. • Ability to read and navigate existing native codebases for accurate migration planning and risk assessment. • Demonstrated track record of publishing multiple mobile applications to the Apple App Store and Google Play Store — Include links or names of published apps in your application. • Experience writing and maintaining Jest unit tests, React Native Testing Library integration tests, and Detox E2E tests. • Strong written and verbal communication skills in English; ability to produce clear technical documentation, ADRs, and onboarding guides. • Familiarity with building management, facility management, or smart building domain applications is a plus. Prior experience in a SaaS product company, especially multi-tenant mobile application contexts is also a plus. Core Competencies Technical Strengths • Cross-platform architectural thinking • Performance-first development mindset • Strong debugging and root-cause analysis skills • Security-aware: token storage, certificate pinning, data encryption at rest • Systematic approach to code quality and testing • Up-to-date with React Native New Architecture evolution Leadership & People • Patient and structured mentoring style • Leads by example — maintains hands-on coding contributions • Clear communicator across engineering, product, and design • Creates psychological safety for junior developers to learn and fail fast • Drives accountability through enablement, not micromanagement • Gives and receives constructive feedback effectively What We Offer • A high-impact, highly visible role: you will lead BRT's mobile engineering transition to React Native. • Greenfield opportunity: the majority of iBMS mobile applications are new products — you shape architecture and user experience from day one. • A meaningful mentorship mission: lead a talented native development team through a well-supported transition, not a rushed rewrite. • Direct collaboration with cloud architects, IoT engineers, and product leadership — a technically rich, cross-disciplinary environment. What to Include in Your Application Please include: • Links to or names of mobile applications you have personally published on the App Store and/or Google Play Store. • A brief description (3–5sentences) of a native-to-React Native migration or team transition you have led. • Your GitHub profile or code portfolio if available.
