Software Development Intern

About Us:

We are an EdTech organization focused on building innovative, accessible solutions to make education inclusive. Our mission is to improve learning outcomes for visually impaired individuals. Our flagship product, Annie, is the world’s first Braille literacy device that empowers visually impaired people to learn Braille independently in any medium of instruction.

You can learn more about us and Annie here. 

Who are we looking for?

We’re seeking a Python Developer with a strong foundation in Embedded and Application Development, experienced in multiprocessing for concurrent applications, Bluetooth Low Energy (BLE) communication, and IART-based (Intelligent Assistive & Real-Time) applications. You’ll be working on Python-powered embedded services that integrate with hardware peripherals to deliver real-time assistive experiences.

What will you be doing?

As an Embedded Software Intern, you'll be contributing to a multidisciplinary team developing innovative solutions for accessible education. You'll get the opportunity to:

• Design and implement Python-based embedded applications

  interacting with real-time hardware.
• Build

  multiprocessing architectures

  to handle concurrent tasks such as sensor data acquisition, Braille cell actuation, and network communication.
• Collaborate with hardware engineers to integrate

  I2C, SPI, UART, and USB peripherals

  into Python applications.
• Develop

  IART modules

  for adaptive assistive features (e.g., responsive Braille learning, speech feedback).
• Optimize

  Python applications on embedded Linux

  for low latency and reliability.
• Create

  diagnostic tools, automated scripts, and testing utilities

  for development and production.
• Debug complex

  software-hardware issues

  using serial logs, GDB, strace, and BLE sniffers.
• Work with Product, QA, and Hardware teams to

  translate user needs into scalable embedded applications

  .

What you'll need to bring to the table?

• Strong proficiency in

  Python

  for

  embedded application development

  .
• Solid experience with

  multiprocessing and multithreading in Python

  for high-performance applications.
• Good understanding of

  embedded Linux platforms

  (Raspberry Pi, custom ARM boards).
• Familiarity with

  hardware-software integration

  (I2C, SPI, UART, USB).
• Proficiency with

  Git

  and collaborative version control workflows.
• Strong

  debugging and performance optimization skills

  using serial logs and profiling tools.

Good to have:

• Experience with

  Raspberry Pi

  ,

  ESP32 (Python/MicroPython)

  , or similar platforms.
• Knowledge of

  RTOS concepts

  (e.g., FreeRTOS) and hybrid systems (Linux + RTOS).
• Familiarity with

  Yocto Project

  for custom Linux builds.
• Understanding of

  bootloaders

  (e.g., U-Boot) and OTA firmware updates.
• Knowledge of

  IoT protocols

  (HTTP, MQTT) for device-cloud communication.
• Develop

  BLE communication layers

  for device pairing, data exchange, and control.
• Interest or experience in

  assistive technologies

  and accessibility-focused solutions.

Compensation:

This internship offers a monthly stipend of 25,000/- rupees. 

Duration:
