Ask HN: Is My Senior Software Salary Low in Seattle?

I've been reading bunch of articles on HN. Especially, this https://www.levels.fyi/SE/Google/Facebook/Microsoft and I just had sad feeling that I'm being under-compensated:

Base: $145K RSU: $100K (split over four years) Signing-Bonus: $40K (split over two years) Software Engineer Experience: 8+ years (this is my 9th year since I graduated with BSc in CS)

Company was a Seattle startup and IPO'ed about 8 years ago (keeping it vague so if company reads this cannot pinpoint who I am)
