Backend Engineer Intern

Role Overview

This is a paid, full-time engineering internship based in Chennai for one month. You will work on real systems at Winsen Labs: building product, testing AI behaviour, improving internal tools, and solving the engineering problems that appear when AI moves beyond a demo. The month is short, so this is a hands-on role from the first day. You will work closely with the team, take ownership of a defined problem, and leave with something real that you built and can explain.

Responsibilities

• Build and improve parts of our AI products and internal systems
• Turn a loosely defined problem into working software
• Test your work against real inputs, edge cases, and failure modes
• Write clear code and document the decisions behind it
• Present what you built and what you learned at the end of the month

Requirements

• AI native: You use coding agents as part of how you build, while still understanding and checking the code they produce
• Strong programming fundamentals and curiosity about how systems work
• Evidence that you build things outside the classroom
• Comfort learning quickly and asking precise questions
• Care for correctness, clarity, and the people who will use your work
• Availability to work full-time from Chennai for the full month
