One of the best sites you can use to find teaching jobs at California Community Colleges is the California Community College Registry. You may also want to visit the websites of community colleges in your area, as some schools may not post every open position to the CCC Registry.
Attending conferences is also an excellent way to find full time or adjunct teaching positions. At every conference, those schools that are hiring leave flyers at the registration desk advertising open positions at their schools. While socializing between sessions, as well as in the evening after the conference sessions, you'll have a great opportunity to meet faculty, learn about potential jobs, and most importantly, form a favorable first impression on exactly those faculty that you are likely to find on your hiring committee.
