Senior Staff Software Engineer - Query Engine

Dremio's Query Planner & Reflections team owns the SQL planner and optimizer, built on Apache Calcite, and the reflections engine that transparently rewrites queries to use pre-computed materializations instead of raw source data. The team sits between SQL and execution, owning the systems that turn queries into efficient plans and make them fast.

As a Senior Staff Software Engineer, you'll set technical direction for these systems: driving ambiguous, cross-team initiatives, raising the bar through design and code review, and growing other senior engineers. Your work will directly affect query performance, correctness, and cost across Dremio's cloud data platform.
