DFT also seems to stand for Design For Testing which is related to manufacturing microchips. here's what Wikipedia has as the first summary:
"Design for testing or design for testability (DFT) consists of IC design techniques that add testability features to a hardware product design. The added features make it easier to develop and apply manufacturing tests to the designed hardware. The purpose of manufacturing tests is to validate that the product hardware contains no manufacturing defects that could adversely affect the product's correct functioning. "
Just browsing through job openings for DFT engineers quickly shows how valuable the information on the field is with salaries getting up to 200k.
