About this role

Hi there,

Our client is building an IoT platform that connects physical devices to mobile, and we are looking for a Senior React Native engineer to own the mobile side of it.

Responsibilities

  • Build and maintain the iOS/Android mobile application

  • Implement core flows: login, profile, asset list, asset registration, gateway registration, BLE discovery / manual entry, alert inbox, alert details, acknowledgement, and activity log

  • Integrate Firebase Auth and push notifications

  • Implement QR scanning and device registration flows

  • Support BLE/device setup flows (scope confirmed separately)

  • Prepare and publish builds via Expo/EAS or equivalent

Required skills

  • React Native and TypeScript

  • Production experience shipping iOS and Android apps

  • Comfortable using AI coding tools (Claude Code, Cursor, Copilot, or similar) day-to-day

  • Firebase Auth and push notifications

  • QR scanning / camera integrations

  • App release and build pipeline experience

Strongly preferred

  • Expo / EAS

  • BLE integration experience

  • Offline or device-configuration flows

  • IoT / mobile hardware interaction experience

A note on how we work: We're a team that leans into modern tooling - AI coding assistants included. We'd love someone who's already made these tools part of their regular workflow, not just tried them out once. It's not a hard requirement, but it genuinely matters to us.


What we offer

  • 1:1 English classes to enhance your communication skills

  • A supportive, collaborative, and dynamic international team

  • All necessary equipment provided

  • 18 days of paid vacation and 7 days of paid sick leave

  • Convenient payroll platform with 20+ withdrawal options and one-click payouts

Does this position sound like a perfect match? We're eager to hear from you!
