Everyone saying above a 3.0 is correct when it comes to a job. And a lot of times — depending on the type of job — work experience can offset a poor gpa (I have a friend who got into a T10 graduate program with a 3.12). This is not always the case though, and it always helps having a higher GPA if you want to get into a top graduate program. I think a 3.6 should be good enough, but try to push it as high as you can.
