The Database team is the bridge between DuckDB and the cloud. We own the core server and client extension logic that lets DuckDB run seamlessly, whether it's local or in the cloud, and we work in C++ right alongside the DuckDB codebase itself. Our mission is to push the boundaries of embedded database performance, distributed execution, and user experience, all while staying closely connected to DuckDB Labs (the team behind DuckDB) to align on APIs and shape what's next.

This role is ideally based in New York City but also open to great candidates remotely on the East Coast.

Own major projects in our dual execution stack, so DuckDB can process queries seamlessly whether they're running locally or in the cloud.

Help build a cloud platform that dynamically assigns resources, so DuckDB stays efficient whether someone's running a tiny workload or pushing our biggest, highest-memory instances.

Lead cross-functional work with our frontend, platform, and infrastructure teams to keep the user experience coherent end to end.

Push the state of the art in embedded database performance, distributed execution, and DuckDB internals.

Deepen your DuckDB expertise and share it with the rest of the company through mentorship and documentation.

Work directly with our support team to debug issues, learn from real usage patterns, and prioritize the improvements that matter most.

Improve systems holistically... spotting architectural challenges early and clearing bottlenecks before they become problems.

Mentor teammates and help raise the bar for engineering practices across the team.

Work closely with DuckDB Labs (which grew out of the Database Architectures group at CWI, where vectorized execution and DuckDB were born) to help align on APIs and shape where DuckDB goes next.

You've built and shipped complex backend systems, and you know what great looks like.
