About ARC Research & Innovation
ARC Research & Innovation is a hardware R&D and product engineering company focused on building durable, high-efficiency smart consumer appliances for Indian households.
Role Overview
Immediate hiring for an IoT Hardware & Firmware Intern for immediate joining. This role involves leading full-system hardware integration and firmware development on an ESP32 platform. The role combines digital electronics, sensor/actuator interfacing, and embedded C/C++ firmware.
Must be able to start immediately (within 24–48 hours).
Key Responsibilities
- Sensor & Actuator Integration: Interface and calibrate AQI / particulate matter sensors (UART/I2C), 4-wire PWM brushless fans, H-bridge DC motor drivers, and MOSFET switching circuits with the ESP32-C3.
- Digital Electronics & Bench Testing: Design breadboard/perfboard prototypes, manage 24V-to-12V/3.3V power rails, resolve logic-level and EMI/noise issues, and validate system stability.
- Embedded Firmware & BLE: Develop modular C/C++ firmware (ESP-IDF / Arduino) for sensor polling, automated speed/cycle logic, Non-Volatile Storage (NVS) state logging, and Bluetooth Low Energy (BLE) GATT communication with an Android app.
- Cross-Team Collaboration: Coordinate remotely with a PCB designer and Android developer to transition from bench prototype to assembled production boards.
Qualifications
- Availability: Must be an immediate joiner able to commit consistent daily hours remotely.
- Pursuing or recently completed a degree in Electronics & Communication (ECE), Electrical Engineering (EEE), Instrumentation, or related fields.
- Solid foundation in digital electronics (MOSFET switching, motor drivers, UART/I2C/PWM, power regulation) and practical circuit debugging.
- Proven hands-on experience integrating AQI / environmental sensors and motors with ESP32 microcontrollers.
What We Offer
- Monthly paid stipend + performance bonus upon V1 launch.
- Complete sensor, actuator, and ESP32 hardware kit shipped directly to your doorstep.
- Internship Certificate and Letter of Recommendation from ARC Research & Innovation.
