Embedded Firmware Developer

Description :

We are looking for a passionate Embedded Firmware Developer with 1.52 years of hands-on experience in developing firmware for IoT controllers. You will work on next-generation connected devices involving ARM-based microcontrollers, low-power design, and wireless connectivity. The role requires strong embedded C/C++ skills, understanding of IoT communication protocols, and an ability to work closely with hardware and software teams to deliver robust, production-grade firmware solutions.

Key Responsibilities:

Firmware Development:

- Design, develop, and maintain firmware for ARM-based IoT microcontrollers (e.g., STM32, SAMD, nRF52), ESP32 etc

- Integrate wired and wireless communication interfaces (UART, I2C, SPI, RS485, Ethernet, LoRa, LoRaWAN, BLE, and Wi-Fi)

- Develop firmware for sensor data acquisition, actuator control, and IoT networking (MQTT/HTTP/TCP-IP).

- Write optimized, modular, and maintainable C/C++ code suitable for low-resource systems.

Hardware & Integration:

- Configure and optimize microcontroller peripherals (ADC, DAC, timers, GPIO, interrupts).

- Develop device drivers for sensors, actuators, and communication modules.

- Troubleshoot and debug hardware-firmware issues using JTAG, oscilloscopes, and analyzers.

- Collaborate with hardware engineers during board bring-up and design validation.

Performance & Reliability:

- Optimize firmware for low power and efficient memory usage.

- Implement power management features (sleep modes, wake-up events).

- Design state machines and multitasking architectures

- Conduct firmware testing, debugging, and validation.

Documentation & Version Control:

- Maintain detailed firmware documentation (architecture, APIs, design decisions).

- Use Git for source control and collaborative development.

- Contribute to design reviews, code reviews, and continuous improvement initiatives.

Preferred Application Domains:

- Experience with Agricultural IoT systems such as soil monitoring, irrigation control, or weather sensing is a strong plus.

- Familiarity with environmental data logging and remote equipment control is advantageous.

Required Qualifications:

- 1.52 years of professional experience in embedded firmware development.

- Proficiency in C/C++ for embedded systems.

- Experience with ARM-based microcontrollers (STM32, SAMD, nRF5x), ESP32 etc.

- Working knowledge of LoRa/LoRaWAN, BLE, and Wi-Fi protocols.

- Experience with UART, I2C, SPI, RS485, Ethernet communications.

- Hands-on debugging with GDB, JTAG/SWD, and protocol analyzers.

- Familiarity with RTOS concepts (FreeRTOS, Zephyr) or bare-metal systems.

- Strong understanding of network protocols (MQTT, HTTP, TCP/IP).

- Good documentation and version control practices (Git).

Nice-to-Have Skills:

- Experience with OTA updates, low-power design, and secure boot mechanisms.

- Familiarity with FreeRTOS, Zephyr, or Nordic SoftDevice.

- Exposure to CI/CD pipelines for embedded development.

- Experience with agriculture or industrial IoT projects.

Education:

- Bachelors degree in Electronics, Electrical, Computer Engineering, or related technical field.

- Equivalent hands-on experience will also be considered.

Tools & Technologies:

- Toolchains: GCC/ARM, STM32CubeIDE, Segger Embedded Studio, PlatformIO.

- Debugging: JTAG, SWD, Oscilloscope, Logic Analyzer.

- Version Control: Git, GitHub/GitLab.

- RTOS: FreeRTOS, Zephyr.

- Networking: MQTT, HTTP, TCP/IP
