About us:

We are a fast-growing technology company specializing in cutting-edge remote monitoring solutions powered by IoT (Internet of Things) technology. Our mission is to empower businesses with real-time data to monitor and control critical assets remotely, enhancing operational efficiency and enabling smarter decisions.

As part of our expansion, we're building a brand-new mobile application to interface with our next-generation sensor systems, and we're looking for a talented React Native Developer to help us bring this vision to life.

Key Responsibilities:

  • Design, develop, and maintain high-quality React Native mobile applications that communicate with IoT sensors.
  • Implement dynamic data visualizations (charts, dashboards, etc.) for real-time sensor data.
  • Collaborate with backend teams to integrate RESTful APIs and GraphQL services.
  • Work closely with UI/UX designers to ensure a seamless and intuitive user experience.
  • Optimize application performance, security, and scalability for both Android and iOS platforms.
  • Debug and resolve issues, ensuring responsiveness and stability of the application.
  • Write clean, maintainable, and well-documented code following industry best practices.
  • Conduct comprehensive testing: unit, integration, and user acceptance testing.
  • Contribute to architecture decisions and new feature planning in an agile development environment.

Required Skills & Qualifications:

  • 4+ years of experience in React Native development.
  • Familiarity with IoT communication protocols and handling real-time data.
  • Solid understanding of RESTful APIs, GraphQL, and backend integrations.
  • Experience deploying apps to the Google Play Store and Apple App Store.
  • Hands-on experience implementing SSO (Single Sign-On) using protocols such as OAuth2, OpenID Connect, or SAML.
  • Familiarity with third-party libraries and native modules in React Native.
  • Awareness of mobile security best practices.
  • Ability to thrive in a fast-paced, agile team environment.

Nice to Have:

  • Experience with Edge Computing and AI/ML in IoT applications.
  • Experience working with Bluetooth Low Energy (BLE), MQTT, or WebSockets.
  • Basic knowledge of Swift (iOS) or Kotlin (Android) for native integrations.
  • Previous experience working with smart home devices or industrial IoT systems.
