Ask HN: What is the average salary of back end/infra devin SF/Bay Area?

Hi there,

I am a systems software guy with 10 years experience in networking (pretty much from bootloader assembly to Python/Go RESTful API). I am now looking for a backend/infra dev position in distibuted/big data systems, but not sure about the market rates.

I just learned from the Tribyte salary thread on HN that big corps offer $300K-$400K/year here. How about medium companies, such as those on Fobes Cloud 100 and Breakout List?

Just want to get some feedback so that I won't ask too much and upset future employers.

Thanks!
