Intern

About the Role

360Watts is seeking a curious, hands-on Embedded Firmware Engineer Intern to work on embedded IoT devices, from early prototypes to custom hardware integration, testing, and real-world deployment. The role requires viewing IoT as a product, not just programming. This is an internship role for 2026 graduates ONLY.

Key Responsibilities

• Embedded Firmware Development:
• Develop and debug embedded firmware using C/C++ on ESP32, STM32, and other ARM-based microcontrollers.
• Work with 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 optimize 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.
• Hardware Integration & Validation:
• 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 analyzers.
• Collaborate with hardware designers and external engineering partners to diagnose hardware–firmware integration issues.
• Participate in prototype testing, field trials, and technical documentation.

Requirements & Tech Stack

• Good 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 (e.g., Wi-Fi, LTE, BLE, LoRaWAN, Thread, MQTT, Modbus, CAN).
• Exposure to OTA, bootloaders, flash storage, or embedded diagnostics.
• Experience reading circuit schematics and debugging embedded hardware.

Qualifications

• Recent graduates in ECE, EEE, E&I, Embedded Systems, or related disciplines.

Job Details:

• Start: Immediate
• Location: On-site (office)
• Salary: Rs. 8k - 10k per month
• Duration: 6 months
• Post-internship, full-time employment is possible.
• Deadline to apply: On or before 13.11.2026
