Senior/Principal Embedded Software Engineer

As part of a small team, you’ll wear many hats. You’ll work closely with hardware, mobile and systems engineers to bring up new boards, debug at the hardware-software boundary, and make sure the device behaves safely in every condition.

• BS in Computer Engineering, Electrical Engineering, Computer Science or a related field \n

• 5-8+ years of embedded software or firmware development on shipped products \n

• Strong C and C++ on resource-constrained microcontrollers (e.g., ARM Cortex-M, Nordic nRF) \n

• Experience with RTOS or bare-metal environments (e.g., Zephyr, FreeRTOS) \n

• Hands-on low-power embedded design experience, and comfort reading schematics and using lab equipment \n

• Git-based workflows, code reviews and CI/CD \n

• Nice to have: motor control, battery-powered wearables, Bluetooth Low Energy, Python test automation, secure OTA updates, and medical device or regulated environments (IEC 62304, ISO 14971) \n

• Design, implement and own embedded firmware for a wearable medical device, from requirements through release \n

• Develop device drivers and interfaces for sensors, motors, power management and peripherals (SPI, I2C, UART, ADC, GPIO), using JTAG for debugging and programming \n

• Implement and maintain BLE communication between the device and the mobile app \n

• Optimize firmware for low power consumption, memory constraints and reliability \n

• Partner with electrical engineers on board bring-up and debug issues using oscilloscopes, logic analyzers and debuggers \n

• Implement safety-critical features, including fault detection, alarms and fail-safe behavior \n

• Build test tools and scripts, and contribute to design controls, risk analysis and verification for a regulated medical device \n
