At 360Watts, we're building next-generation Energy IoT products with edge computing for intelligent energy management, connecting rooftop solar, batteries, appliances, grid and user experience.

We're looking for a curious, hands-on Embedded Firmware Engineer Intern. You'll work on embedded IoT devices from early prototypes to custom hardware integration, testing and real-world deployment. You need to think IoT as a PRODUCT and not just programming.

The role is an internship. We look only for 2026 graduates ONLY. On-going college students will not be considered.

// YOUR ROLE i) Embedded Firmware Development — Primary Focus:

- Develop and debug embedded firmware using C/C++ on ESP32, STM32 and other ARM-based microcontrollers.
- Work on bare-metal programming, interrupts, timers, memory management, peripherals and real-time embedded systems.
- Develop firmware using FreeRTOS/RTOS, including task scheduling, inter-task communication and concurrency.
- Implement and optimise communication over wireless protocols such as Wi-Fi, LTE/4G, LoRaWAN and Thread, and application protocols such as MQTT and HTTPS.
- Work with wired interfaces and industrial protocols such as UART, SPI, I²C, RS485/Modbus and CAN.
- Develop reliable firmware features including OTA updates, watchdogs, fault recovery, diagnostics, logging and offline data handling.
- Explore Python-based embedded development, MicroPython and emerging edge computing applications.

ii) Hardware Integration & Validation — Supporting Focus:





- Read and understand electronic schematics, component datasheets and hardware interfaces.
- Support firmware bring-up and debugging on development boards and custom PCBs.
- Test and validate hardware using digital multimeters, regulated power supplies, oscilloscopes and logic analysers.
- Collaborate with hardware designers and external engineering partners to diagnose hardware–firmware integration issues.
- Participate in prototype testing, field trials and technical documentation.

// YOUR ELIGIBILITY

- Recent graduates in ECE, EEE, E&I;, Embedded Systems or related disciplines.
- Positive fundamentals in C/C++
- Hands-on project experience with MCUs such as ESP32 (or) STM32
- Experience with ESP-IDF, STM32CubeIDE, FreeRTOS or other embedded development frameworks.
- Exposure to wireless protocols involving cloud & edge IoT (eg. Wi-Fi, LTE, BLE, LoRaWAN, Thread, MQTT, Modbus, CAN).
- Exposure to OTA, bootloaders, flash storage or embedded diagnostics.
- Reading circuit schematics and debugging embedded hardware.

// HOW TO APPLY

- Share your project portfolio (photos/videos with description)
- GitHub links
- A brief note describing the most interesting hardware project you've built

// JOB DETAILS

- Start: Immediate
- Location: On-site (office)
- Salary: Rs. 8k - 10k per month
- Duration: 6 months
- Post-internship, full-time employment is possible based on performance and technical growth.
