Pretty much all the big tech companies have a presence here.
From what I can remember, Microsoft (Azure Storage), Amazon (ML Alexa Teams), Google, Uber (ATG), Argo AI, Aurora, Facebook (Oculus), Duolingo, and Apple are all have offices in the city.
In the suburbs I think Netapp and Oracle have offices.
Uber, Google, Apple, Facebook, Amazon all are present. What’s clearly wrong or at least misleading about this data is that they represent only a small fraction of the tech workforce in pgh. Other than Uber and Google these are only small offices. They also happen to be some higher paying jobs within those organizations. The reality is that most tech people in Pittsburgh are looking at jobs at UPMC, PNC, NetApp or a handful of smaller companies and poorly funded startups, few of which pay particularly well nor have worthwhile equity comp even relative to the low COL small markets.
This 170k median doesn’t fit with other stats available, and is only true if your sample is limited to FAANG and unicorns, which exists, but is small in Pittsburgh.
