Embedded Systems

About the internship: Selected intern's day-to-day responsibilities include: 1. Develop firmware on Espressif Systems ESP32 using C/C++, ESP-IDF, and Arduino to read sensors and drive actuators for climate control, irrigation, dosing, and horticultural lighting in the hydroponics farm 2. Build closed-loop control logic using PID and state machines for pH/EC dosing, HVAC, CO control, humidity regulation, and LED photoperiod scheduling 3. Implement connectivity and telemetry features including MQTT sensor streams to the cloud, remote set-point handling, and reliable OTA firmware updates 4. Work on Linux SBC platforms such as Raspberry Pi and NVIDIA Jetson devices to aggregate ESP32 nodes, run local control as a cloud-down fallback, and expose local APIs using Python 5. Visit the farm to debug real hardware by scoping sensor buses, fixing misbehaving nodes, and deploying fixes on the same day 6. Own small subsystems end-to-end including wiring, firmware development, testing, and deployment on a live hydroponics farm Who can apply: Only those candidates can apply who: are available for full time (in-office) internship can start the internship between 18th Jul'26 and 22nd Aug'26 are available for duration of 1 month have relevant skills and interests are Electronics Engineering students Stipend: INR₹ 15,000 - 18,000 /month Deadline: 2026-08-17 23:59:59 Other perks: Certificate, Letter of recommendation, Flexible work hours Skills required: Python, Linux, Raspberry Pi, Embedded Systems, Arduino, C Programming, C++ Programming, Internet of Things (IoT) and ESP32 Other Requirements: 1. Pursuing or recently completed BTech/BE/MTech in electronics, electrical, ECE, mechatronics, instrumentation, or a related field 2. Has built at least one non-trivial embedded project end-to-end (not just a breadboard) - share the repo, schematic, or demo video 3. Comfortable with C/C++ on microcontrollers and Python on Linux; hands-on with at least two of I²C, SPI, UART, ADC, PWM, interrupts 4. Can read a datasheet, use a multimeter, and solder a clean joint 5. Willing to be on-site full-time at our Mumbai farm for the entire internship 6. Bonus: ESP-IDF/FreeRTOS, OTA experience, MQTT/Home Assistant/ESPHome, PID & control theory, hydroponics or horticultural lighting exposure, KiCad/EasyEDA, open-source firmware contributions 7. High agency, low ego, takes things apart to figure out how they work About Company: Humankind must produce more food in the next four decades than it did in the last 8,000 years of agriculture combined. We are a purpose-driven startup working to reimagine farming from the ground up. At Cosy, we are committed to transforming cities into sustainable food landscapes by providing fresh, nutritious, and eco-friendly produce because the food we eat should be simple, clean, and, more than anything, tasty!
