Yes, I’ve found jobs via recruiters. They usually specialize in a location and skillset, tho. Not everyone on this site is in SV, and we have no idea what you do.
Don't pay a recruiter. The employer always pays the recruiter. If the recruiter wants you to pay them, they're up to no good and you don't want to work with them anyway.
Do you have a LinkedIn profile? Polish it up and mark it as open to recruiter inquiries, and you'll almost certainly start getting outreach. A lot of them will be spray-and-pray spam recruiters, but here and there will be someone who approaches both you and the employer with respect and consideration.
You may also be able to find a few local agencies by googling. Be specific about location and skillset or title. They're typically thrilled to be able to add candidates to their stable.
If you have a professional network locally, they may also be able to recommend recruiters they've worked with.
