IOT Developer

We’re looking for a hands-on IoT Intern with a passion for hardware, embedded systems, and sustainable tech to support the integration, testing, and optimization of our custom-built IoT kits deployed across farms. You'll work closely with our engineering team to fine-tune our ESP32-based system and contribute to real-world deployments.

Key Responsibilities:

• Assist in developing, testing, and deploying ESP32 firmware for our field IoT devices.
• Work with a variety of sensors (Soil NPK, Temp, Humidity, pH, Leaf Wetness, GPS, BME280, Hall Sensors, Rain Gauges).
• Implement and test communication protocols:
• MQTT via GSM (A7670C using TinyGSM)
• LoRa (SX1262) for kit-to-kit communication
• RS485 Modbus for soil sensor interfacing
• Optimize power management using LM2596S voltage regulation and relay-controlled low-power modes.
• Write and debug embedded C/C++ code for sensor data acquisition and communication.
• Capture and verify GPS coordinates using TinyGPS++.
• Monitor battery and solar charge levels using CN3795 MPPT and ESP32 ADC channels.
• Build heartbeat and health-check modules to ensure uptime and device status.
• Contribute to data formatting and structuring for MQTT payloads (JSON preferred).
• Assist with on-field deployment and troubleshooting.

Tech Stack & Tools You’ll Use:

• Microcontroller: ESP32
• Protocols: MQTT, Modbus RS485, LoRaWAN, UART, I2C, Analog
• Libraries: TinyGSM, TinyGPS++, ModbusMaster, RadioLib, Adafruit BME280, A3144, etc.
• Power: LM2596S, Relay Modules, CN3795 MPPT, 11.1V Li-ion
• Sensors: Soil (NPK, Temp, Moisture, pH, EC), Weather (BME280, Rain Gauge, Wind Sensors), Positioning (GPS NMEA).
• Tools: Arduino IDE / PlatformIO, Logic Analyzers, Multimeters
• Communication: MQTT Broker (Mosquitto), AT Commands

Skills / Qualifications:

• A final-year undergraduate or recently graduated student in Electronics, Mechatronics, Electrical, or Embedded Systems.
• Comfortable with C/C++ programming for microcontrollers.
• Basic experience with IoT protocols (MQTT/LoRa/Modbus).
• Familiarity with sensor integration, debugging, and communication protocols.
• Bonus: You’ve tinkered with ESP32, built a DIY weather station, or participated in IoT hackathons.
• Strong problem-solving and documentation skills.
• Willing to learn fast and work on field prototypes.
• Real-world experience in precision agriculture IoT systems.
• Opportunity to work with a team building India’s most advanced farm IoT platform.
• Mentorship from senior embedded engineers and IoT architects.
• A chance to transition into a full-time role post-internship based on performance.
• Exposure to edge-to-cloud architecture, field deployment challenges, and sensor calibration techniques.
