Working Student Python Engineer

At dltHub, we're building on the success of dlt, the most popular open-source library for data loading in Python with over 2 million monthly downloads. After proving its value in the OSS community, we’re now building dltHub to make data engineering accessible to all Python developers.dltHub is a workspace and runtime that empowers any Python developer to build, run, and maintain data pipelines, transformations, and notebooks, without needing a data platform or infrastructure team.

As a working student, you’ll be joining a team where students don’t just assist, they build. Several amazing students already work with us, creating impactful demos and owning their projects with real independence.

Our team is based in Berlin, now growing into other locations, especially across the US. Founded by experienced data and ML engineers, we're backed by Foundation Capital, Dig Ventures, and technical founders from Hugging Face, Instana, Matillion, Miro, MotherDuck, Datadog, Mode, and Rasa.

Our team is driven by clear values: we speak with courage, build what matters, automate relentlessly, show up with energy, deliver on commitments, and win together.

If you thrive in a fast-paced environment and want to help shape a product that’s changing how developers work with data, let’s talk.
