We are building a hardware-software product that deploys Android-based edge devices in commercial environments. The device operates in a real-time, always-on mode and must perform reliably in production settings, with zero tolerance for failure during active operation. Most of the surrounding software stack — cloud backend, web dashboards, and mobile applications — is developed with the assistance of AI tooling under close human direction. The edge device hardware layer is the one part of the system where physical iteration on real hardware is required. Role Overview You will own the edge device systems layer end-to-end, including: - USB hardware I/O - Custom Android (AOSP) ROM - Device security - Field testing and deployment You will also review and guide Kotlin application code (including AI-generated output) to ensure correctness, safety, and alignment with system constraints. Responsibilities - Design, implement, and maintain USB pipelines (Host & Gadget), ensuring strict latency and timing requirements - Test, validate, and debug USB and hardware compatibility issues in real-world environments - Build and maintain a custom Android (AOSP) ROM with system-level modifications, including: - Kiosk mode and restricted production environments - Auto-start, watchdog services, and cellular connectivity (APN/modem) - OTA updates with staged rollout and rollback - SIM lock and device control mechanisms - Implement and enforce device security, including: - Secure boot, locked bootloader, and full-disk encryption - Hardware-backed attestation (Keystore / TEE) - Certificate pinning, mTLS, and signed payload verification - Disabling ADB and debug access in production - Define and execute device provisioning workflows, including field testing and hardware validation - Develop hardware specifications and provisioning documentation - Review Kotlin code (including AI-generated output) for correctness, safety, and architectural compliance - Enforce clear separation between hardware I/O and application logic
