Backend & Data Engineer

We build AI-powered products internally and support portfolio companies with complex data and AI infrastructure challenges. We are looking for an engineer who enjoys building the foundation beneath AI systems: data pipelines, backend services, storage architecture, APIs and the infrastructure that turns messy real-world data into usable products.

This is a hands-on role with significant ownership and direct exposure to founders, operators, and investors.

THE ROLE

You will own the data and backend layer behind AI products and internal platforms.

This is not a pure ML role. We need someone who enjoys designing databases, building ingestion systems, operating data infrastructure, and shipping production services. AI sits on top of that foundation.STACKPython
