Yo and slippyfish replays are very good. Here are a few more options.
-The North Face is in Alameda
-Mountain Hardwear they are going through a rough time but might be good
-Marmot Santa Rosa I believe
-Hydrapak in Oakland small but not bad working there
-Marin Bikes don’t know what they have but maybe worth a look
-Leap Frog which is a toy company I believe is located there
-Tesla which I believe does most of the design in LA but they have a plant in San Leandro
Other industries that I believe have footholds up there are toy companies, adult toy companies, transportation startups, marijuana product companies, Bicycle Part Manufactures
I would caution about Specialized Bikes I have had a number of friends work there and it is a tough environment
If you are willing to move to LA there are even more opportunities. Lots of different industries in Socal.
