Design, develop, and maintain firmware for STM32 microcontrollers.
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 Free RTOS 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)
