I haven't been able to find an academic study specifically looking at software engineering or tech jobs, but there are other studies I've seen that send out identical resumes (with just the name changed) suggesting that men are generally perceived to be more competent.

Science faculty reading resumes for a "laboratory manager" position prefer the male candidate http://www.pnas.org/content/109/41/16474.abstract

Academic psychologists are more likely to suggest hiring the male candidate http://advance.cornell.edu/documents/ImpactofGender.pdf
