- Integrate the POS with payment terminals, Kitchen Display Systems, kitchen printers, and other restaurant floor devices;
- Implement device communication for connected and disconnected states using TCP/IP, sockets, UDP, and IoT protocols;
- Build native Android modules using Kotlin and Java for hardware and protocol access and expose them to React Native through native modules and TurboModules;
- Design edge-compute and device topologies to ensure the POS continues operating during cloud connectivity outages;
- Implement zero-touch onboarding and fleet provisioning for Android tablets;
- Own the device lifecycle, including provisioning, monitoring, remote configuration, OTA updates, and decommissioning.

- Experience integrating payment terminals at the device level, including tokenization and payment gateways;
- Experience in the QSR or retail industry.
We are looking for a Senior React Native Engineer to own device and hardware integration for a new Android tablet-based POS platform, bridging the React Native application layer with physical restaurant hardware including payment terminals, Kitchen Display Systems, and printers. You will build native Android modules in Kotlin and Java, implement device communication over TCP/IP, sockets, and IoT protocols, design offline-first edge-compute topologies, and own the full Android device lifecycle including zero-touch provisioning and OTA updates. The role requires active use of AI-assisted development tools as part of daily engineering practice.
