Job summary

Salientmotion is seeking an embedded software engineer to work on firmware and hardware cross-functional tasks in a defense-focused setting. The role centers on writing C code for STM32 microcontrollers, debugging board-level issues, and collaborating with electrical engineers on motor controllers and actuators.

Daily work includes bringing up hardware, reading schematics, and using oscilloscopes to diagnose timing and signaling problems. The position requires U.S.

Qualifications

U.S. Citizenship required for defense projects.
2–3 years embedded C programming experience.
RTOS experience: ThreadX/FreeRTOS/Zephyr or similar.
Experience with SPI, I2C, CAN, UART, Ethernet, or BiSS-C interfaces.
Hardware debugging using oscilloscope/logic analyzer; schematic reading.

Responsibilities

Write firmware in C for STM32 microcontrollers, focused on motor controllers.
End-to-end development: derive requirements, design, implement and verify.
Bring up new hardware and debug with motor-control and electrical engineers.
Support mechanical team with actuator design and verification.
Diagnose Ethernet PHY CRC errors by analyzing RMII timing and board design issues.

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.)
Hardware debugging - Oscilloscope and/or logic analyzer experience
Software debugging - JTAG/SWD debugger experience (J-Link, Lauterbach, Ozone, 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.
