## About the Role

Do you have experience in Rust (programming language)?, * 7+ years professional Python with real, substantive experience in both of the following (not just one):

Perferred background:

 * Prior experience with a FastAPI + Django hybrid codebase.
 * MongoDB (pymongo, aggregation pipelines).
