Job description

Job Summary

Junior Embedded Engineer - Onsite Bengaluru, ECE / EEE / Instrumentation / related branches.

Role overview

We are looking for motivated embedded engineers to join our onsite hardware team. You will work on live, production-grade devices writing firmware, integrating sensors and actuators, and building the controllers that growers and farm operators depend on every day. This is not a training internship. You will be contributing to real products from week one.

What you will do

• Firmware development: Write and maintain firmware for microcontroller-based devices (ESP32, STM32, Arduino-class). Implement reliable control logic for sensors, pumps, valves, and dosing systems deployed in the field.
• Sensor & hardware integration: Interface with analog and digital sensors (EC, pH, temperature, humidity, flow, level) and actuators. Handle communication protocols I2C, SPI, UART, /Modbus and bring up new hardware from bare board to working device.
• IoT & connectivity: Connect devices to our platform using MQTT and real-time data streams over WiFi/GSM. Build firmware that reports device state accurately and responds to remote commands reliably.
• Testing, debugging & collaboration: Test and debug on real hardware using multimeters, oscilloscopes, and logic analyzers. Work within a structured team using GitHub for version control and code reviews. Write clean, maintainable code and share regular progress updates.

Who this role is for

• Engineering graduates or final-year students in ECE, EEE, Instrumentation, or related branches
• Self-learners who have built things personal projects, academic projects, or hobby electronics
• Engineers who want to work on real deployed hardware, not breadboard demos
• Individuals who take ownership of tasks, communicate proactively, and follow through
• Fresher

Key skills & traits

• Solid understanding of embedded C / C++
• Microcontroller programming (ESP32, STM32, Arduino, or similar)
• Reading schematics and datasheets, and basic circuit understanding
• Serial communication protocols I2C, SPI, UART
• Hands‑on debugging with multimeter / oscilloscope
• Problem‑solving mindset and ability to debug independently

Good to have

• MQTT or other IoT data protocols
• / Modbus for industrial devices
• PCB design (KiCad / Eagle / Altium)
• RTOS basics (FreeRTOS)
• Python for test scripts or tooling
• Any hardware project you can demonstrate or show working
