Those skillsets are not something you can acquire through QA work. You either need the relevant education or a very strong sense of self-learning. What I mean to say is that your QA work has often very little to do with actual game development.
That said, it's a great "network" tool and gives you plenty of opportunity to show that your work goes beyond "I enter bugs in JIRA".
Oh yeah, forgot to include that.
I also want to add that most company policy allows QA to get access to document related to development which can help you when you want to applied to different position.
Soft skills is also important. Leadership skills or training skill allow him to move to different position related as QA, mainly QA trainer, QA lead, or project manager
