• Develop motor controller/ESC algorithms for our various products

• Implement and debug low-level drivers (GPIO, UART, SPI, I2C, CAN, USB, ADC, timers, DMA)

• Develop firmware using C/C++ (bare-metal and/or RTOS environments)

• Work with STM32 HAL/LL, CMSIS, and vendor toolchains

• Integrate firmware with hardware designs and collaborate closely with hardware engineers

• Debug and troubleshoot issues using tools such as JTAG/SWD, logic analyzers, oscilloscopes

• Optimize firmware for performance, memory usage, and power consumption

• Participate in code reviews and follow best practices for embedded software development

• Write and maintain technical documentation

• Support manufacturing, testing, and field issues as needed

Required Qualifications

• Bachelor’s degree in Electrical Engineering, Computer Engineering, Computer Science, or equivalent experience

• Experience with AC/BLDC motor control algorithms

• Strong experience developing firmware for STM32 microcontrollers

• Proficiency in embedded C/C++

• Solid understanding of microcontroller architectures, peripherals, and datasheets

• Experience with bare-metal development and/or RTOS (FreeRTOS or similar)

• Familiarity with debugging embedded systems using JTAG/SWD

• Experience using Git or other version control systems

Preferred Qualifications

• Experience with FreeRTOS or other real-time operating systems

• Knowledge of low-power design techniques

• Experience with bootloaders and firmware update mechanisms

• Familiarity with communication protocols (CAN, Ethernet, USB)

• Experience bringing up new hardware revisions

• Exposure to automated testing or CI for embedded systems

Nice to Have

• Experience with other MCU families (NXP, Nordic, Microchip, TI)

• Basic understanding of hardware schematics

• Experience with safety-critical or regulated products

• Knowledge of embedded security concepts (secure boot, firmware signing)

What We Offer

• Opportunity to work on real-world embedded products

• Collaborative environment with hardware and systems engineers

• Competitive compensation and benefits

• Room for technical growth and ownership
