Junior Embedded Engineer (Internship to Job)

**Job Description** **Junior Embedded Engineer** Onsite * Bengaluru * ECE / EEE / Instrumentation / related branches City Greens is a fast-growing AgriTech startup building automation and AI-driven solutions for Controlled Environment Agriculture (CEA). Our platforms combine hardware, IoT, and AI to help modern farms, institutions, and agri-enterprises improve productivity, efficiency, and sustainability. We design and build the electronics that run commercial farms — control panels, sensor networks, dosing and irrigation controllers, and the IoT devices that connect physical farm hardware to our software platform. **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, RS485/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. **Requirements** **Requirements** *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 *Key skills & traits* **Required** * 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 * RS485 / 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 **Benefits** *What we offer* Internship-to-full-time pathway This role begins as a 3-month onsite, unpaid internship focused on real contribution and performance. Interns who demonstrate technical ability, ownership, and consistent delivery will be offered a full-time position. Starting salary ₹25,000 / month Coverage Health insurance * Work on production hardware — not sandbox projects * Exposure to IoT-integrated, real-time control systems * Structured code review and mentorship from the hardware team * Growth into senior firmware, hardware design, or platform roles check(event) ; career-website-detail-template-2 => apply(record.id,meta)" mousedown="lyte-button => check(event)" final-style="background-color:#6875E2;border-color:#6875E2;color:white;" final-class="lyte-button lyteBackgroundColorBtn lyteSuccess" lyte-rendered="">
