Job summary

Salient Motion is seeking an embedded software engineer to work across firmware and hardware for defense-grade motion control systems. You will write C for STM32 microcontrollers, bring up new hardware, and debug board-level issues alongside electrical and mechanical engineers.

The role is primarily on-site in Torrance, CA, with relocation assistance and comprehensive benefits. U.S. citizenship is required for defense projects.

Qualifications

U.S. citizenship is required for defense projects.
2–3 years embedded C programming experience.
Experience with RTOS such as ThreadX, FreeRTOS or Zephyr.
Experience with multiple communication interfaces (SPI, I2C, CAN, UART, Ethernet or BiSS-C).
Ability to read schematics and debug hardware using scopes/logic analyzers.
On-site work required (majority on-site presence).

Responsibilities

Write firmware in C for STM32 microcontrollers, focusing 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 hardware issues (e.g., Ethernet PHY CRC errors) using oscilloscope analysis.

Job description

**Applicants must be U.S. Citizens or U.S. Permanent Residents (Green Card holders) to meet customer and regulatory requirements**

Who We Are

We are pioneering modular motion technologies to power the next generation of innovation for Industrial, Aerospace and Defense. If you're excited about disrupting legacy industries, and passionate about motor control technology, let's chat!

We are at the forefront of innovation, crafting exclusive motion control components that propel the industrial, aerospace, and defense sectors into the future.

A Couple Other Things

We are open to relocating you
We have great benefits
We are well funded, and already generating revenue
We are located in beautiful Torrance, CA and just moved into a new large hangar facility

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 an $300B+ market! Come join us and help build next generation systems that will make a massive impact at global scale.
