Job Overview
We are looking for a skilled Firmware Engineer to design, develop, debug, and maintain embedded firmware for microcontroller-based products. The ideal candidate should have strong hands-on experience in Embedded C, STM32 microcontrollers, RTOS, and peripheral interfacing, along with a good understanding of embedded systems and debugging.
Key Responsibilities
Design and develop embedded firmware for STM32-based microcontroller systems.
Develop efficient, reliable, and maintainable firmware using Embedded C/C++.
Work with RTOS for task scheduling, inter-task communication, synchronization, and resource management.
Develop and integrate drivers for peripherals such as UART, SPI, I2C, GPIO, ADC, PWM, Timers, CAN, etc.
Configure and work with STM32 MCU peripherals using STM32CubeIDE/CubeMX or equivalent tools.
Debug firmware using JTAG/SWD, logic analyzers, oscilloscopes, and other debugging tools.
Perform root-cause analysis of firmware, hardware-interface, and system-level issues.
Develop and execute unit, integration, and system-level testing for embedded firmware.
Optimize firmware for memory usage, performance, power consumption, and real-time response.
Collaborate with hardware, electronics, systems, and testing teams during product development.
Participate in code reviews and maintain technical documentation.
Support firmware integration, validation, and product releases.
Required Skills & Experience
Bachelor's degree in Electronics, Electrical, Instrumentation, Computer Engineering, or a related field.
2–5 years of hands-on experience in embedded firmware development.
