**Workplace:** remote

## Description

We are seeking a high-calibre Senior Mobile Developer to lead the development of our next-generation IoT ecosystem. In this role, you won't just be building apps; you will be architecting the bridge between physical hardware and digital user experiences. 

You will be responsible for designing and developing high-performance, cross-platform applications from the ground up, ensuring seamless low-latency communication with IoT devices via BLE, Wi-Fi, and MQTT. The ideal candidate thrives on solving complex hardware-software synchronization challenges and is passionate about building "offline-first" resilient architectures. 

Key Responsibilities 

-   End-to-End Development: Architect, develop, and maintain robust React Native applications for iOS and Android from initial concept to App Store/Play Store deployment. 

-   Hardware Integration: Implement and optimize communication protocols between mobile devices and IoT hardware (provisioning, pairing, and real-time telemetry). 

-   Native Bridge Engineering: Write custom Native Modules (Java/Kotlin/Swift/Objective-C) when necessary to access low-level hardware features that standard React Native libraries cannot reach. 

-   State & Data Management: Build sophisticated "offline-first" capabilities, ensuring data integrity when devices are disconnected from the cloud. 

-   Performance Optimization: Minimize battery consumption and memory usage, specifically during continuous background hardware scanning and data streaming. 

-   Security Orchestration: Implement end-to-end encryption for device-to-mobile and mobile-to-cloud communication. 

Technical Requirements & Skillsets 

Core Mobile Expertise 

-   Frameworks: Mastery of React Native and its ecosystem (Hooks, Context API, Fabric Architecture). 

-   Languages: Strong proficiency in TypeScript/JavaScript, with the ability to write/debug Swift/Objective-C and Java/Kotlin. 

-   State Management: Expertise in Redux Toolkit, Zustand, or MobX for handling complex asynchronous hardware states. 

IoT & Connectivity Stack 

-   Protocols: Deep experience with Bluetooth Low Energy (BLE) (specifically the react-native-ble-plx or react-native-ble-manager libraries). 

-   Networking: Experience with MQTT, WebSockets, and gRPC for real-time bi-directional communication. 

-   Device Onboarding: Proven ability to implement Wi-Fi Provisioning (SoftAP, SmartConfig) and NFC pairing flows. 

Backend & Infrastructure 

-   API Integration: Expert-level knowledge of RESTful APIs and GraphQL. 

-   Storage: Experience with local persistence using WatermelonDB, SQLite, or Realm. 

-   DevOps: Full ownership of the CI/CD pipeline for mobile (Fastlane, Bitrise, or GitHub Actions).

## Requirements

-   Education: Bachelor’s or Master’s degree in Computer Science, Electrical Engineering, or a related field. 

-   Experience: 5+ years in Professional Mobile Development, with at least 2+ years specifically focused on IoT-integrated products. 

-   Product Portfolio: A proven track record of shipping at least 2-3 production-grade IoT apps currently available in stores. 

-   Problem Solving: Strong understanding of concurrency, multi-threading, and hardware latency issues. 

Bonus Points For: 

-   Experience with AWS IoT Core or Google Cloud IoT. 

-   Familiarity with C/C++ or firmware development concepts. 

-   Knowledge of Matter or Thread protocols.
