Why we read it this way (5)
The posting explicitly states that none of the listed desirable experience items are 'a hard gate' — every named technology therefore appears as preferred rather than required.
Python/FastAPI and Ruby/Rails are presented as alternatives for the same full-stack requirement ('and/or'), so they are captured as paired preferred skills rather than independent hard gates.
Relational data modeling is mentioned as desirable but names no specific database product; PostgreSQL is included as the canonical representative given the fintech/treasury context, but the posting does not name a specific RDBMS.
No minimum years of experience are stated in the posting.
The role appears to be Chicago-based (DRW HQ); no explicit remote option is mentioned.
