I know plenty of tech companies that make sure female applicants get interviewed by at least one female engineer during the hiring process. They have a good faith belief this reduces discrimination rather than increasing it.
Of course, it could stray into discriminatory territory if you're doing something dumb - like sending all minority applicants to a hardass interviewer who rejects everyone; or giving certain employees a burdensome number of interviews on the basis of their race, at the cost of their other duties. But you should already be on top of issues like that anyway.
