All DIRECTV staffing is done through their website www.directv.com. Under the "about us" tab is a link to the hiring management system. Enter a detailed profile and attach your resume. Be sure you clearly list your skills. You will also be able to see all positions company-wide listed. But post your profile even if you don't see a current opening in your area of interest. This is the DIRECTV recruiter's first stop in looking for candidates.
If you can find someone who works at DIRECTV, they have a good employee referral program. So be sure to ask them to take in your resume. A good professional networking tool is "linkedin.com". It is free and will gain you access to many professionals in companies of interest.
