Niche embedded firmware skillset and product focus reduces applicant density.
STM32, FreeRTOS, bootloader and hardware-debug skills are highly domain-specific and not easily transferable.
Explicit mandatory 3–5 years and detailed bootloader, FreeRTOS, and STM32 requirements enforce strict filters.

Design, develop, and maintain embedded firmware in C for STM32 microcontrollers, covering bare-metal drivers and FreeRTOS applications.
Develop secure bootloader and firmware update mechanisms including encryption, digital signatures, and anti-tamper protections.
Debug hardware-level issues, collaborate on board bring-up, support production and field teams, and maintain engineering documentation for firmware projects.
3 to 5 years of hands-on embedded firmware development experience in a product company.
Bachelor's or Master's degree in Electronics, Electronics & Communication, Instrumentation, Computer Engineering or related discipline.
Strong proficiency in Embedded C and bare-metal STM32 programming including startup code, linker scripts, interrupts, and clock configuration.
Practical experience developing FreeRTOS applications and writing bootloader code with secure firmware update implementations.
Experienced in low-level peripheral driver development (UART, I2C, SPI, ADC, DMA, timers) and serial communication debugging.
Familiar with firmware security concepts such as AES encryption, digital signatures, secure boot, and STM32 readout protection.
Comfortable with hardware debug tools (ST-Link/J-Link, oscilloscope, logic analyser) and working independently with distributed teams.
