Head hunters and job search advise

Hi! Never had difficulty find a job before and things are not great at my current job right now I’m looking to move in the next 1-2 months. Any suggestions on head hunters for product management or digital marketing roles in SF Bay Area? I’m finding product mgt really difficult to crack right now, although I’m already a product manager at a very large company. Also, appreciate referral at large giants in the Bay Area. THANK YOU for your help & advice! Really need it!
