Lead Embedded Systems Engineer

The Role

Were seeking an

Embedded Systems Engineer

to build the intelligence layer of our modular indoor farming systems. This is not a maintenance role.

You will own the complete electronics and embedded stack of our farming units. You will be responsible for setting up the architecture, building a large part of it yourself.

About Us

Humanity must produce more food in the next four decades than we have in the last 8,000 years of agriculture combined.

At Cosy, we are redesigning farming as a controlled, modular, and scalable system built next to where people live. We believe food production should be precise, reliable, and repeatable - not dependent on weather or distance.

We are building environmental control machines that grow food.

Location: Goregaon, Mumbai.

Who You Are

You are a hands-on embedded systems builder.

Youve shipped real hardware.

Youve debugged field failures.

You understand that controlling physical systems is very different from writing software.

You think in systems:

Sensors Control Logic Actuators Safety Data Deployment.

You care about reliability more than features.

You are comfortable making architecture decisions.

You take ownership.

What Youll Own

Electronics hardware

PCB design from schematic to bring-up, and the control panel that runs each unit (power, protection, wiring, connectors)

Firmwar

e - real-time control in C/C++ on ESP32 microcontrollers: sensing, actuation, fail-safes, OTA updates

Control logic

the algorithms that actually grow the crop: dosing, calibration routines, climate behaviour, safety interlocks

Connectivity

MQTT/cloud telemetry, alarms, and the data interface between firmware and our farm software

Production and field -

testing and QC of every unit before dispatch, commissioning at hotel sites, debugging live deployments

Engineering standards

schematics, wiring documentation, firmware architecture and version control, so the system outlives any one person

Requirements

3-6 years of experience in embedded systems / hardware automation

Strong proficiency in C/C++ and python for microcontrollers

Experience working with microcontrollers (ESP32, STM32, Raspberry Pi or similar)

Understanding of real-time control systems and non-blocking architecture

Experience integrating sensors and controlling actuators

Knowledge of communication protocols (I2C, SPI, UART, MQTT)

Basic understanding of power electronics and hardware debugging

Experience deploying hardware systems outside of lab environments

Strongly Preferred

RTOS experience

Experience in robotics, EV systems, industrial automation, or IoT hardware startups

Experience designing systems that require high reliability

Exposure to cloud integration for IoT systems

What We Offer

High ownership from day one

Direct impact on core product architecture

Opportunity to build a scalable environmental control system from the ground up

Collaborative, hands-on startup environment

Fresh herbs to take home .
