Best practices for UX/Design-led application development in Foundry

I’m looking at a project lifecycle where a partner is implementing a core Palantir solution for a client. In these engagements, is there typically a dedicated role for a UX or Product Designer to lead the end-user application design?

Specifically, I’m interested in whether teams usually have a designer focused on wireframing and workflow logic in tools like Workshop and Slate, or if that design work is generally expected to be handled by the Forward Deployed Engineers (FDEs) or Application Developers?
