Job summary

Salient Motion in Torrance, CA is looking for an embedded software engineer who can work across firmware and hardware. You will write C for STM32 microcontrollers, bring up new hardware, and debug board-level issues with scopes and schematics.

This role involves end-to-end development from requirements to verification, collaboration with motor-control and electrical engineers, and supporting actuator design and verification on defense projects.

Qualifications

• 2–3 years embedded C programming experience.
• RTOS experience - ThreadX, FreeRTOS, Zephyr, or similar.
• Communication interface experience - SPI, I2C, CAN, UART, Ethernet.
• Hardware debugging with oscilloscopes/logic analyzers; schematic reading.
• On-site presence required (majority on-site).

Responsibilities

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

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
• 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
