FSI has a curriculum design team in DFW but I have no info on pay or hours for that job. They are very careful to have every training event scripted and constantly harp on sticking to the approved master document list.
Each center has a curriculum support team as well, but again I had no contact with them in SAV.
Again, you're welcome and good luck. When I went job hunting at FSI there was very little to go on. I'm happy to pass on my research and experiences. It is a great job for the right person and a very stable company.
