Hourly rate for mechanical designers?

Hello,

I’d like to know the hourly rate range for an experienced mechanical designer/design engineer in the San Jose/San Francisco area.

First of all I’m a US citizen currently living in the UK. I’ve been here since 1991 and I’m looking to return to San Jose.
I have 40 years experience working primarily in the high tech industry. You can find out more about me on LinkedIn

I’d also appreciate names of agencies specialising in mechanical design contractors.

Thank you for taking the time in reading my post.

I would benchmark some companies and check sites like glassdoor.

I’ve done that, unfortunately it’s difficult to find contract hourly rates. Most contract jobs are advertised by agencies and unlike in the UK rarely include the rate offered. Sites like glassdoor only show annual salaries, at least that’s all I’ve been able to find. Not really helpful.
Thanks for your suggestion.
Miguel
