I don’t know why they are on there, but YC startups list their batch and year in parentheses on job posts, e.g. (W25). Example: https://www.workatastartup.com/jobs/88812
The Plaid listing you linked doesn’t have a batch by their name.
Still kinda weird that a non-YC company gets to have job listings on a site for only YC companies.
