Only a tiny minority of AWS employees work on/in/around the data centers. Quick research shows an average of ~0.2-0.3 employees per MW for large DCs, so at best it's gonna be a couple hundred jobs.
Power transfer stations also don't have a lot of jobs on site. But they provide infrastructure for millions of jobs.
