LF: S.H.I.E.L.D. Agent Tony Stark
I'm looking for an AU fic that was either a Steve/Tony or a Steve/Bucky/Tony pairing. It was an AU where Tony was a S.H.I.E.L.D. field agent prior to Iron Man 1. I can't remember for certain but I think Tony ended up working with Steve and Natasha as a member of STRIKE. But I could be wrong. I might be mixing it up with a different fic.
