Embedded Electronics & Firmware Engineer - Internship (WFH & Part Time)

About the internship:Selected intern's day-to-day responsibilities include:

1. Nordic & Zephyr C Firmware: Build low-power, event-driven state machines on ARM Cortex-M using Zephyr RTOS and Nordic nRF Connect SDK.

2. End-to-End BLE Stack: Implement GATT services, custom advertising, connection management, and OTA DFU workflows.

3. Low-Power Profiling: Budget coin-cell power, size reservoir capacitors, and measure \mu\text{A}-level sleep currents using a Nordic PPK2.

4. KiCad/Altium PCB Design: Draft schematics and multi-layer layouts with RF/antenna considerations and assembly-ready DFM standards.

5. Mixed-Signal & Sensor Integration: Tune analog resistor ladders and interface SPI/I2C sensors (LIS3DH, W25Q32 flash, RTC).

6. Bench Debugging & Rework: Perform fine-pitch SMD hand-soldering, hot-air rework, and signal analysis with oscilloscopes and logic analyzers.

Core tools: nRF Connect SDK/Zephyr, KiCad/Altium, PPK2, oscilloscope, logic analyzer, hot-air/soldering station, multimeter, J-Link debugger.2.Preferred background: B.E./B.Tech ECE / E&TC (Electronics & Communication / Telecommunication). Mechatronics acceptable with firmware depth.Note: While we understand that you may not have ALL the requisite qualifications, but if you pass most checkboxes and have built a related product (IoT/PCB related), then feel free to apply.About Company:We are a startup looking to develop a new product.

We are not a lala company. In fact, we are not a company yet. If the product develops, we will establish a company and reward the individual appropriately who is willing to put their genuine efforts.

Looking for honest, dedicated and hardworking individuals who want to own a responsibility and have genuine interest in their work.
