Job Summary

We are looking for a hands-on Embedded Firmware Engineer with 2–4 years of experience in embedded firmware development, hardware interfacing, debugging, and troubleshooting. The candidate will be responsible for developing, testing, debugging, and maintaining firmware for microcontroller-based electronic systems.

The ideal candidate should have strong knowledge of C/C++ programming, microcontrollers,

communication protocols, sensors, real-time systems, and hardware debugging, along with the ability to troubleshoot issues at both firmware and hardware levels.

Key Responsibilities

- Develop, integrate, test, and maintain embedded firmware for microcontroller-based systems.
- Develop firmware using Embedded C/C++.
- Work with microcontrollers such as STM32, NXP, TI.
- Develop and integrate drivers for sensors, peripherals, communication interfaces, and external devices.
- Implement and debug communication protocols including UART, SPI, I2C, CAN, RS232,

RS485, USB, Ethernet, PWM, ADC and GPIO.
- Interface and troubleshoot sensors such as current/voltage sensors, and other peripherals.
- Develop firmware for real-time control, monitoring, data acquisition, and communication applications.
- Perform firmware debugging using JTAG/SWD, debugger, logic analyzer, oscilloscope,

serial terminals, and other tools.
- Troubleshoot hardware–firmware integration issues and identify root causes.
- Analyze communication failures, timing issues, memory issues, watchdog resets, crashes,

and peripheral failures.
- Develop and implement fault detection, diagnostics, logging, and recovery mechanisms.
- Perform unit testing, integration testing, hardware bring-up, and system-level validation.
- Work closely with PCB/hardware engineers during board bring-up and troubleshooting.
- Analyze firmware logs and test data to identify system-level problems.
- Optimize firmware for performance, memory usage, power consumption, and reliability.




- Maintain source code using Git or equivalent version-control systems.
- Prepare firmware documentation, test procedures, troubleshooting reports, and technical specifications.

Required Technical Skills

- 2–4 years of experience in embedded firmware development.
- Strong programming skills in Embedded C/C++.
- Hands-on experience with STM32 or similar microcontrollers.
- Good understanding of microcontroller architecture, interrupts, timers, DMA, ADC, PWM,

GPIO, watchdogs, and memory.
- Solid knowledge of UART, SPI, I2C, CAN, RS232/RS485, USB and Ethernet.
- Experience with RTOS concepts such as tasks/threads, queues, semaphores, mutexes, and timers.
- Experience with debugging tools such as JTAG/SWD, ST-Link, oscilloscopes, and logic analyzers.
- Good understanding of hardware–firmware interaction.
- Experience with Git and structured software development practices.
- Ability to read schematics and understand electronic circuits.

Preferred Skills

- Experience in UAV, robotics, automotive, battery/BMS systems.
- Experience with STM32CubeIDE, STM32CubeMX, Keil, GCC, PlatformIO, or equivalent development environments.
- Experience with FreeRTOS or other RTOS platforms.
- Experience interfacing with IMU, GNSS/GPS, magnetometer, barometer, CAN devices,

ESCs, motors, and actuators.
- Knowledge of MAVLink, UAV communication protocols, or autopilot systems is an advantage.
- Experience with bootloaders, firmware update mechanisms, and OTA/serial firmware updates.
- Basic knowledge of Python or scripting for test automation is an advantage.
- Experience in developing automated hardware-in-loop or bench-testing setups is desirable.

Desired Attributes

- Strong troubleshooting and debugging skills.
- Good understanding of both hardware and firmware.
- Ability to independently diagnose failures using test equipment and logs.
- Strong analytical and problem-solving ability.
- Comfortable working on prototype hardware and performing board bring-up.
- Ability to work closely with PCB, mechanical, system, and testing teams.
- Good documentation and communication skills.
- Ability to work in a fast-paced R&D; environment
