Note that Adam Waite doesn't appear in the extensive development credits for either Jurassic World Evolution, nor Planet Coaster.Probably means that other Devs were making the tools, now Adam (and others - remember, he's been moved from working on something else, which is now done presumably!) are utilising them, and tweaking things based on internal tester feedback, and player feedback.
Doesn't sound like something to worry about.
He does, however, appear regularly in livestreams and the forums discussing Elite Dangerous.
I'm gonna hazard a guess and say he works full-time on Elite Dangerous.
