Non-Agency/ABS/Structured Credit Trading to Buy Side

Associate from a desk with a strong market presence in Mortgage Credit needs a change of scenery. I am the associate on a market leading desk in Non-Agency Mortgages in both loans and bonds spaces. Thinking I need more responsibility and the ability to be more big picture and not just defined by one niche market. Has anyone ever made the jump from a structured credit sell-side desk to doing structured credit at one of the mega funds like Apollo or Blackstone? Have a few things I’m looking at and just curious what other people have experienced
