Senior Firmware Engineer

Our devices deliver real-time location intelligence for patients, staff, and assets across hospitals worldwide. The hardware must be reliable, power-efficient, and maintainable at scale across thousands of deployed units in regulated healthcare environments.

• 3+ years of embedded/firmware engineering experience on commercial hardware products.
• Electronics background: able to read schematics, review PCB layouts, and validate hardware designs independently.
• Hands-on hardware skills: comfortable with soldering, bring-up, and manual testing of embedded systems.
• Understanding of radio/wireless fundamentals: antennas, BLE, UWB, NFC, or related protocols used in positioning systems.
• Demonstrated use of AI coding tools in daily workflows (Claude, GitHub Copilot, or equivalent).
• Strong written and verbal communication in English.

Nice to have:

• Nordic Semiconductor (nRF series) and Zephyr RTOS experience.
• Exposure to indoor positioning technologies (RTLS, IPS, UWB ranging).
• Python for scripting, tooling, or test automation.
• Background in healthcare IoT or regulated device environments.

Hardware design & validation:

• Review and validate PCB schematics, component selection, and board-level design decisions before production.
• Catch issues early at the schematic stage.

Firmware development:

• Build and maintain production firmware for Nordic Semiconductor (nRF) microcontrollers including BLE and UWB radio stacks.

Hands-on testing & bring-up:

• Set up and run hardware test environments.
• Prototype on breadboards, solder, validate device behavior.
• Own bring-up from first-article boards through to production qualification.

Device reliability:

• Implement health monitoring mechanisms to ensure continuous device operation in the field.

• Own reliability from firmware to fleet.

• Write and review embedded C firmware for nRF-series microcontrollers using Zephyr RTOS.

• Review hardware schematics and validate PCB designs to identify and flag issues before production.

• Prototype and bench-test hardware setups; solder, debug, and validate devices hands-on.

• Implement and maintain watchdog, reset, and device health monitoring logic for production deployments.

• Collaborate with the Location Engine team to ensure reliable, low-latency data delivery from device to cloud.

• Apply AI-assisted development practices (Claude Code or equivalent) to accelerate firmware development and code review.

• Contribute to design decisions covering the full product lifecycle — requirements, component selection, enclosure validation, bring-up, and release.
