Senior Software Engineer ID74262

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 Subway’s 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.

Must haves

4+ years of software engineering, including hardware- or device-integrated systems;

Solid React Native + TypeScript;

Hands-on native Android (Kotlin and/or Java), including building and bridging native modules to React Native;

Strong grasp of device and networking protocols: TCP/IP, sockets, UDP, IoT;

Experience with offline-first app development;

Android device-fleet provisioning (zero-touch enrollment, device-owner / kiosk modes);

Experience using AI-assisted development tools (Claude, GitHub Copilot) day to day;

Upper-intermediate English level.

Nice to haves

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.
