Job Summary
Firmware Engineer
Candidate Profile (Must Have)
Experience: 5 years of commercial experience in embedded projects (bare metal or RTOS).
Language & Tools:
Strong C skills; CMake/Make; GCC/Clang or MCU vendor toolchains; Git; debugger tools (J-Link / ST-Link); trace and profiling tools.Microcontrollers:
ARM Cortex-M (e.g. STM32 / NXP / Infineon) or equivalent; ability to read and apply datasheets and reference manuals.HAL / Drivers:
Design and modification of low-level drivers (GPIO ADC PWM I2C SPI UART watchdog timers) as well as drivers for external peripherals (e.g. EEPROM).Communication:
CAN bus (filters masks bitrates transceivers termination); basic knowledge of SocketCAN (Linux); design of application-level communication protocols.Bootloader / Firmware Update:
Experience in bootloader implementation firmware updates (e.g. via CAN) integrity verification (CRC) rollback mechanisms and secure update strategies.Measurements & Protections:
Design and validation of current voltage and temperature measurements (ADC oversampling calibration) and protection mechanisms (thresholds hysteresis time-based debouncing).Software Architecture:
Design of modular software architecture: clear layer separation (HAL/Drivers Services Protocol Application) state machines event loops interface abstractions.Quality & Testing:
Integration testing functional verification error logging and tracing; ability to develop Linux-based test tools (SocketCAN).Documentation:
Technical specifications (drafting review) block diagrams in-code documentation changelogs and environment setup instructions.
