• Department: Software Development
• Reporting To: Director (R&D) or Senior Manager (Software Development)

Job Purpose

To take full ownership of BRT’s mobile engineering function. This is a leadership-plus-hands-on role with three interconnected mandates.

Key Responsibilities

• 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.

Addition Responsibilities

• Any reasonable task assigned by management and deemed to be within the individuals’ capabilities to ensure smooth running of the business.

Required Qualifications & Experience

React Native & JavaScript Ecosystem

• 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 (3–5 sentences) of a native-to-React Native migration or team transition you have led.
• Your GitHub profile or code portfolio if available.

Working Conditions

• We provide a professional, fun and exciting work environment where innovation and creativity thrive!
