Company Description
Agrayan is revolutionizing agriculture by integrating conversational intelligence with IoT to enhance farming practices. Our conversational AI solutions empower farmers with actionable insights, transforming traditional methods into intelligent, data-driven approaches. By blending agronomy and cutting-edge technology, we work closely with farmers to co-create innovative agricultural models and strategies. This collaboration drives efficiency and improves crop productivity on a global scale.
Description :
We are looking for a passionate Embedded Firmware Developer (fresher or early career) with 0-2 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:
- 1.5-2 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
