It sounds like you are in a specialized field, which means that there has to be a recruiting firm that covers the industry. Seek them out.
Also, I would network with old coworkers. They are all working somewhere. There could be a position waiting for you there.
Good job sites are: www.indeed.com and www.simplyhired.com
Good luck.

Your current company won't know you are looking unless you tell them.
