Job Overview

nWe are looking for a skilled Firmware Engineer to design, develop, debug, and maintain embedded firmware for microcontroller-based products. The ideal candidate should have solid hands-on experience in Embedded C, STM32 microcontrollers, RTOS, and peripheral interfacing, along with a good understanding of embedded systems and debugging.

nKey Responsibilities

nDesign and develop embedded firmware for STM32-based microcontroller systems.

nDevelop efficient, reliable, and maintainable firmware using Embedded C/C++.

nWork with RTOS for task scheduling, inter-task communication, synchronization, and resource management.

nDevelop and integrate drivers for peripherals such as UART, SPI, I2C, GPIO, ADC, PWM, Timers, CAN, etc.

nConfigure and work with STM32 MCU peripherals using STM32CubeIDE/CubeMX or equivalent tools.

nDebug firmware using JTAG/SWD, logic analyzers, oscilloscopes, and other debugging tools.

nPerform root-cause analysis of firmware, hardware-interface, and system-level issues.

nDevelop and execute unit, integration, and system-level testing for embedded firmware.

nOptimize firmware for memory usage, performance, power consumption, and real-time response.

nCollaborate with hardware, electronics, systems, and testing teams during product development.

nParticipate in code reviews and maintain technical documentation.

nSupport firmware integration, validation, and product releases.

nRequired Skills & Experience

nBachelor's degree in Electronics, Electrical, Instrumentation, Computer Engineering, or a related field.

n2–5 years of hands-on experience in embedded firmware development.
