Full Job Description
**Applicants must be U.S. Citizens or U.S. Permanent Residents (Green Card holders) to meet customer and regulatory requirements**
About the role:
We need an embedded software engineer who can work across firmware and hardware. This is not a pure software role - the candidate will use oscilloscopes, read schematics, and debug board-level issues alongside writing C code. What you'll do:
Writing firmware in C for STM32 microcontrollers, particularly but not limited to motor controllers
End to end development: derive requirements, design/architect to satisfy requirements, implementation and verification.
Bringing up new hardware and debugging issues alongside motor-control and electrical engineers
Support mechanical team with new actuator design and verification
Example real task: Diagnosing why an Ethernet PHY reports CRC errors by analyzing R MII clock timing with an oscilloscope, reading the PHY datasheet, and identifying a board design issue.
What you need:
U.S. Citizenship - Required for defense projects
Comfortable working on defense-related projects
2-3 years embedded C programming experience
RTOS experience - ThreadX, FreeRTOS, Zephyr, or similar
Communication interface experience - Must have worked with at least 2-3 of: SPI, I2C, CAN, UART, Ethernet, BiSS-C
Embedded peripheral experience - Must be comfortable with Analog-to- Digital Converters, Timers, Memories (Flash, EEPROM, fRAM etc.)
Schematic reading - Able to look at a circuit diagram and understand signal flow
On-site - Majority on-site presence required (at least 4 out of 5 days)
Nice to haves:
DO-178C / DAL certification experience (aerospace software safety standard)
Motor control background: FOC, Space Vector Modulation, current loops
Sensor experience: Hall sensors, incremental encoders, absolute encoders
What we have to offer:
We are not just building components. We are reshaping the future of the Aerospace and Defense component industry, which is a $300B+ market! Come join us and help build next generation systems that will make a massive impact at global scale.
We offer competitive compensation: $120,000 to $140,000 base salary + equity
Exceptional healthcare benefits, Medical is 100% covered by the company
