Role We are looking for a Firmware Engineer to develop a modular and scalable firmware platform for microcontroller-based hardware. The engineer will be responsible for hardware interfacing, device drivers, communication protocols, and configurable firmware. Responsibilities • Develop firmware using Embedded C/C++ for Arduino, STM32, ESP32 or similar microcontrollers. • Develop drivers/interfaces for buttons, switches, potentiometers, encoders, LEDs, displays, servos, stepper motors, sensors, relays and other I/O devices. • Implement GPIO, ADC, PWM, timers, interrupts, filtering, debouncing and calibration. • Develop USB/Serial and communication protocols such as UART, I2C, SPI, CAN, USB HID, etc. • Design a Hardware Abstraction Layer (HAL) and reusable device-driver architecture. • Develop a configurable/preset-based firmware system where hardware pins, devices and parameters can be configured through PC software without rewriting firmware. • Implement device detection, identification, configuration, error handling and firmware updates. • Debug firmware and hardware using serial tools, multimeters, oscilloscopes and logic analyzers.



• Work closely with hardware/PCB and software teams to integrate firmware with the overall system. • Maintain firmware documentation, version control and testing. Required Skills • Strong Embedded C/C++ knowledge. • Hands-on experience with Arduino / STM32 / ESP32 or similar MCUs. • Good understanding of GPIO, ADC, PWM, UART, USB, I2C, SPI and interrupts. • Experience in embedded communication protocols and device drivers. • Knowledge of Git, debugging and hardware testing. • Good understanding of electronics and microcontroller-based systems. Valuable to Have • Linux / Embedded Linux. • Linux device driver development. • Embedded driver development. • FreeRTOS / RTOS. • USB HID. • Bootloaders and firmware update mechanisms. • PCB debugging. • 74HC165 / 74HC595 and I/O expanders. • Experience developing generic/configurable firmware platforms. Qualification • B.Tech/B.E./M.Tech in ECE, EEE, Instrumentation, Computer Engineering or related fields.• Freshers with strong hands-on embedded projects may also be considered.
