Software Engineering (Internship)

This is a paid, full-time remote engineering internship with six months on the product engineering team, shipping features. Our stack is Angular on the front, .NET on the back, PostgreSQL or SQL Server underneath, Kafka between services. You will use Claude Code daily, which means the typing is fast and the thinking is the job: is this the right design, did the agent get the edge case wrong, does the test actually prove anything. Interns who do excellent work often get a full-time offer with us before the six months are up.

What you will work on

A real feature, end to end: the screen, the API, the data model, the tests. Small at first, bigger as you go.

Reviewing AI-generated code and writing down what it got wrong. We keep a list.

Writing automated tests with Playwright and xUnit, and shipping through the CI/CD pipeline.

Fixing real bugs from real customers, with the person who reported them in the loop.

Handing over what you built so another engineer can change it without asking you.

What we are looking for

Final-year students or recent graduates in Computer Science or a related field, or self-taught and able to show it.

You have built and deployed a web application, in any stack. We will teach you ours.

Some TypeScript or C#, or the willingness to pick them up fast.

You already use an AI coding tool and you have opinions about when it is wrong.

You care whether the code works in a month, not only whether it ran today.

How to apply

Send a link to something you built and deployed, with a sentence on the design decision you would change now. A repo with a readme and a commit history counts for more than a CV.
