Firmware Engineer

About this role

Join a well-funded aerospace and defense startup in Torrance, CA as a Firmware Engineer developing motor control firmware for next-generation motion technologies. You'll write embedded C code for STM32 microcontrollers while collaborating closely with hardware engineers to debug board-level issues using oscilloscopes and other test equipment.

What you'll do

• Develop firmware in C for STM32 microcontrollers, focusing on motor control applications
• Execute end-to-end development cycle from requirements analysis through design, implementation, and verification
• Debug hardware issues using oscilloscopes and logic analyzers alongside motor control engineers
• Bring up new hardware prototypes and diagnose board-level problems
• Support mechanical team with actuator design and verification
• Work with communication interfaces (SPI, I2C, CAN, UART, Ethernet, BiSS-C) and embedded peripherals

What they're looking for

• C firmware development
• STM32 microcontroller programming
• Real-time operating systems (RTOS: ThreadX, FreeRTOS, Zephyr)
• Oscilloscope and hardware debugging
• JTAG/SWD debugging tools (J-Link, Lauterbach, Ozone)
• Schematic reading and circuit analysis
• Communication protocols (SPI, I2C, CAN, UART, Ethernet)
• Embedded peripherals (ADC, timers, memory management)

Benefits

• Competitive salary $120,000–$140,000 plus equity
• 100% company-covered medical insurance
• Flexible PTO
• 401(k) retirement plan
• Relocation assistance available
• Majority on-site role in new facility

Likely interview questions

• Walk us through a time you debugged a board-level issue using an oscilloscope—what problem did you find and how did you solve it?
• Describe your experience with real-time operating systems—which have you used and how did you handle scheduling or task synchronization?
