Senior Backend 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 our commercial offering, dltHub, to make data engineering accessible to all Python developers.

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 .

Why we want to hire you

We're building a new service from the ground up that brings together the dlt library, an LLM-first development workspace, and data lake storage and runtime for data pipelines and notebooks. This takes our stack beyond Python into new languages, infrastructure, and systems. We're looking to grow the team with people who bring the right skills and background.

Our focus is on deeply understanding user needs and developing the best technologies to meet them. To make that happen, we’re looking for smart, driven people who will, over time, take ownership of key parts of the product.
