First, get a map from Bike Pittsburgh here:

I'm not that familiar with the area where you will work, other than passing it on the Parkway West to get to the airport. But I think you'll be intimately familiar with the topography of Pittsburgh commuting from the Northside or Southside to Foster Plaza, going from the river floodplain to one of the higher spots in the area. It looks like you could reach Foster Plaza via the West End (watch yourself at the West End Circle area) and then Noblestown Road. Bike Pittsburgh has some sections of Noblestown marked "cautionary bike route" so take that into consideration.
