As an Embedded Software Engineer II, you will own specific components of our embedded stack, working close to the hardware on the real-time firmware that our safety devices depend on. Most of your time will be spent in RTOS environments (Zephyr and FreeRTOS) and on bare-metal targets, architecting safety-critical systems where reliability is a hard requirement.
What You'll Do
- Design and implement robust C/C++ firmware for safety-critical embedded devices
- Architect and implement RTOS-based firmware on Zephyr and FreeRTOS, including task/scheduling design, ISR handling, inter-task communication, memory and stack budgeting, and deterministic timing analysis
- Write low-level peripheral drivers and board support code
- Interface RTOS devices with Embedded Linux user-space applications
- Maintain and improve CI/CD pipelines (GitLab) to automate testing
- Bring up new hardware and debug complex issues using JTAG/GDB
- Collaborate with safety team to ensure code adheres to IEC 61508 standards
What You Bring
- 3-5 years hands-on embedded software development
- Strong C proficiency with working C++ knowledge
- Production RTOS experience (Zephyr, FreeRTOS, ThreadX, or similar)
- MCU peripheral fluency with datasheets and linker scripts
- Embedded Linux user-space familiarity
- IP networking protocols and standard interfaces (UART, SPI, I2C, USB, CAN)
- Python scripting and CI/CD workflow experience
- Oscilloscope, logic analyzer, JTAG, and GDB debugging skills
- B.S. in Computer/Electrical Engineering, Computer Science, or equivalent
Bonus Skills: Zephyr expertise, wireless stacks (BLE, ISM, Wi-Fi), Functional Safety background, BSP/device driver knowledge, static analysis/MISRA C familiarity
Salary: $125,000-$150,000
