There are always openings, but there are also a lot of nurses. Generally speaking, if you look at the major metropolitan areas (Seattle, Tacoma, Olympia, Portland, Salem, Eugene) you'll find enough hospitals that someone will likely offer you a job. You're likely to have some competition for a great job at a great hospital (e.g., nurses will shank you like a prison snitch if they think you're competing for the same job at one of the children's hospitals), but if you're flexible and willing to also look at smaller hospitals in satellite cities (Beaverton, Tualatin, Oregon City, Sea Tac, Federal Way, Lacey, etc) you'll find something. A lot of people take jobs in small hospitals in the Providence or Legacy systems and then transfer internally to the larger hospitals. Newberg Medical Center is kind of famous for being the entry way to Providence. We also have a lot of areas that qualify for loan repayment, especially along the coast or the eastern part of the state.
Basically, we have plenty of jobs, but you may have to put in a lot of applications to find one that meets your needs. Your experience will put you ahead of the ridiculous number of new grads coming out of Seattle and Portland every year, but we still have a lot of nurses, so be prepared.
