That’s basically table stakes for a senior engineer no? At that point you should ask for a bit more salary and a better bonus structure or RSUs
As a general observation, salaries reflect the costs of living. So given the exact same experience and qualifications a SE in San Francisco,CA will earn more than one in Little Rock,AK.
So living in SEA where labor is cheaper and living costs are lower than the USA, the salaries for SEs would also be lower.
