Pros
Great people, fun mission, interesting job with interesting history, excellent health care benefits and PTO. Newly implemented cost of living raise a nice move.
Cons
Management. Your experience entirely depends on your manager. If you get one of the middle-managers who cares, you'll love it. Otherwise you work under one of the other kinds of middle-managers or almost all of the department heads, and you will have to fight to be able to take that generous PTO and justify sick time off. Many managers have insane expectations but zero time for training/orientation, and upper management preaches one thing but puts policies in place that practice another. Not an employee-focused institution. The salary is low for Seattle, so consider this a good stepping stone but not your forever job.
