ABOUT THE ROLE We are looking for a Senior React Native Engineer to build modern tablet applications for restaurant environments, integrating with payment terminals, kitchen devices, and cloud services on Android. You will develop offline-first experiences using React Native, Expo, Redux Toolkit, and React Navigation, consume backend APIs, and implement hardware integrations for POS systems. The role applies AI-assisted development practices and Spec-Driven Development in a POS Engineering team. WHAT YOU WILL DO - Integrate the POS with payment terminals, Kitchen Display Systems, kitchen printers and other restaurant floor devices; - Implement device communication for connected and disconnected states over TCP/IP, sockets, UDP and IoT protocols; - Build native Android modules (Kotlin / Java) for hardware and protocol access and expose them to React Native via native modules / TurboModules; - Design edge-compute and device topologies so the POS keeps working when cloud connectivity is lost; - Implement zero-touch onboarding and fleet provisioning for the Android tablet fleet; - Own the device lifecycle: provisioning, monitoring, remote configuration, OTA updates and decommissioning.

NICE TO HAVES - Experience migrating a legacy Windows / OPOS POS to a cross-platform native stack; - C / C++ or JNI for low-level device work; - Cloud IoT platforms (AWS IoT Core / Greengrass or similar); - Cross-platform device frameworks (e.g. Qt); - Payment-terminal integration at the device level (tokenization, gateways); - QSR or retail experience. PERKS AND BENEFITS - Professional growth: Mentorship, TechTalks, and personalized growth roadmaps. - Competitive compensation: USD-based pay with education, fitness, and team activity budgets. - Exciting projects: Modern solutions with Fortune 500 and top product companies. - Flextime: Flexible schedule with remote and office options.
