Just a heads up that NETworks has had that listed on their website for quite a long time. It's more a way for them to funnel resumes to one central place and does not really reflect any actual openings. Of course, it never hurts to submit every now and then as you do never know when they might need to fill a position.
Edited to add: I just noticed that they actually posted this same request for resumes on Playbill today, so maybe they do actually have some positions to fill at this time.
