That confused me too. I think they just don't have as nuanced a vocabulary when it comes to the different roles in software development. To them, a software developer is the company that makes the software product, and/or everyone involved in making it, including designers and SWEs. Figma does have features specifically made for developers rather than designers, but my guess is that's not what they're talking about, they just mean "software people".
