Software Engineering Internship

You know the drill: you are looking for a new housemate, you post a message online, and you receive 150 responses. Chaos. No overview. No sense of who actually suits you.

That is why we are building Dingdong: the ultimate platform to find your perfect housemate more easily. With our app, we make searching for a room or housemate more social, smarter, and more enjoyable.

Every day, thousands of students and young professionals use Dingdong. Behind every swipe, chat, and match runs a mobile infrastructure built with React Native, Django, PostgreSQL, Firebase, and Google Cloud.

As we grow rapidly, it is becoming increasingly important to understand how users engage with the app. Where do people drop off? Which screens load slowly? Where do errors occur during registration, login, or matching?

Therefore, we are looking for a Software Engineering intern from September 2026 to help us make Dingdong faster, more stable, and more reliable. 🚀

💻 What will you do?

During this practical internship, you will help us make Dingdong faster, more stable, and more user-friendly. We want to better understand how the app is used in practice: where users get stuck, which parts can be improved, and where technical enhancements are required.

You will investigate this and contribute to solutions in both the app and backend. Think of improving app performance, analysing and resolving bugs, testing on various devices, setting up monitoring, and translating user feedback into concrete product improvements.

Thus, you will not only work on code but also on the quality of the overall user experience. You will examine what users need, translate this into technical improvements, and help prepare Dingdong for further growth.
