Data and ML Engineers have nothing to do with Games. Their job is to process Data and get new information out of it. It is much more likely this role will have to work with the EShop data or maybe the NSO in general. One major area is there the tracking data, to identify what people actually do when surfing on the website. Most interesting is there where people stop, because then Analysts can identify why the people didn't buy. But there are a lot of other use cases, all not gaming related at all. Of course, it could be that these engineers are processing Multiplayerdata too, but this would also mostly related to get Data from A to B, nothing which would directly go into gaming.
If you search for people, who might work on features which result in better gaming experience, it is more likely a classic Hardware or Software Engineer (specialized on hardware driver). They would work on improvements of the gaming experience. But to be honest, I don't see these positions US based. As long they partner with NVidia, it would be anyway best, if they use their resources, as they have the best engineers employed. And other Hardware was yet always mostly japan based developed.
The description is about ML algorithms running on native hardware from how much they talk about power consumption.
Do not expect very advanced ML algorithms to be used considering they're talking about these running on the CPU.
