Redfin's a good example. They're at every UW CSE career fair and Glenn Kelman (Redfin's CEO) gives talks on campus every now and then.
My original comment was a bit too focused on the companies' side of things. I think the main issue is a lack of awareness on the part of students. In my experience (as a current undergrad at UW), students simply don't know about the local startup scene and thus don't take the steps to capitalize on it. Given the decent number of organizations and meetups in the area that would provide good avenues for students to get involved (Seattle Tech Startups, Startup Weekend, Hops & Chops, TechCafe, etc), it's more a matter of connecting the dots than developing new social structures.
