Test Engineering Companies

Feel like Boeing will be the the end of my technical skills if I don't find something new or different to work on. I've always been fortunate to work in a lab setting where I can develop and write tests for hardware. With much of the work no longer staying around SoCal, seems wise to think about the future of my career. I don't consider myself a developer by any means but I feel comfortable writing code/scripts for hardware testing. Are there any companies that may offer similar work? If so how do you enjoy it and how stable is the job?
