About the Role Join a fast-moving, NYC-based AI-native data infrastructure company that is building the next generation of agentic analytics.

As a Senior Software Engineer on the Distributed Data Systems team , you'll own core platform components end-to-end, with a particular focus on query performance and join optimization. If you get genuinely excited about JOIN order optimization or have ever implemented a query optimizer for fun, this role was written for you.

What We're Looking For Required: 4+ years of experience as a data systems, backend, infrastructure, or platform engineer. Proficiency in Haskell and/or TypeScript (the core tech stack).

Strong foundation in algorithms and data structures and their real-world applications. Experience with OLAP lakehouse / data lakehouse architecture and query optimization .
