Thanks for the feedback, ambershee. We're looking more for a UE4 generalist with a focus on level design. We've updated the posting, hopefully this is more clear.
Yep, they are the same thing but you'll find that different renderers/engines name it differently. In Marmoset Toolbag it is Albedo, in UE4 it is Base Color etc.
On a side note, the Fabric Engine 2 is launching at Siggraph, this includes Modo integration alongside that of UE4, Maya and XSI. https://vimeo.com/135353349
