I've heard great things about the SaaS scene in Seattle, and there are definitely some companies that stand out for their engineering culture and work-life balance. Companies like Zillow, Expedia, and Tableau are usually mentioned as having a strong focus on work-life balance, and they're all pretty well-established in the area. But if you're looking for something a bit more on the high-growth side, you might want to check out companies like Outreach, Moz, or Apptio - they're all growing fast and have a reputation for having a great engineering culture, with things like flexible hours and professional development opportunities.
