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.

• Valuable 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. Good 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.

Pay: ₹400,000.00 - ₹800,000.00 per year
