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!
