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.

Significant concentration of AI & ML teams probably raises the median (thanks to CMU). Some of the hottest skills in the market today.

Facebook also has a FAIR office in addition to Oculus in Pittsburgh.
