• Develop and maintain firmware on bare metal microprocessors and embedded Linux platforms, including device‑level components and drivers where applicable.
• Build firmware applications for Gatekeeper and Face First devices; optimize performance, power usage, and reliability.
• Develop internal tools/scripts to support diagnostics, data collection, testing, and performance validation.
• Support hardware bring‑up: board validation, peripheral integration, and early prototype debugging.
• Work with common device interfaces and sensors (e.g., GPIO, UART, SPI, I2C, ADC) and wireless modules (BLE/Wi‑Fi/LTE as applicable).
• Investigate problem reports and field issues: collect logs, reproduce failures, isolate root cause, implement fixes, and document outcomes.
• Use appropriate debugging tools and techniques (e.g., serial logs, core dumps, GDB/JTAG; oscilloscope/logic analyzer as needed).
• Create and maintain unit/integration tests where applicable; support regression testing and release validation.
• Produce clear technical documentation (how‑to guides, troubleshooting steps, release notes) to improve team efficiency and supportability.

• Proficiency in C/C++, Python, bare metal and Linux‑based development.
• Strong embedded Linux experience; kernel/u‑boot/driver‑level experience as applicable to the role.
• Familiarity with Yocto (or similar embedded Linux build systems).
• Familiarity with common embedded interfaces/peripherals (UART/SPI/I2C/GPIO).
• Demonstrated debugging ability: log‑driven diagnosis, issue isolation, and use of lab/test tools as needed.
• Ability to analyze performance, optimize memory footprint, and design for low‑power systems.
• Strong problem‑solving skills and ability to work effectively in a fast‑moving environment.

• Experience building for edge gateways (Intel/ARM SBCs), including deployment/packaging approaches.
• Familiarity with containerization (Docker/Kubernetes).
• Knowledge of IoT systems and device‑to‑cloud architectures (e.g., Azure IoT, GCP equivalents).
• Experience with firmware update mechanisms, versioning, OTA updates, and remote diagnostics.
