• You have a solid grasp of query planning or better yet – contributed to a production‑grade query engine or related projects (e.g. Trino, Calcite, Substrait, DataFusion, etc.) ideally demonstrated through open‑source contributions or PMC membership on projects.

Benefits and Growth:

• Get to build tools for software engineers, just like yourself. And use the tools we build to accelerate our development.
