Two fine resources I have used in Texas are the Texas Workforce Commission, which not only will post your resume for employers to search, but can give you advice and counseling on your job search. Also, texascomputerjobs.com.

I found my current job via the Texas Workforce Commision. My current HR had searched their database and found my resume, and they called me. They had not advertised they were looking to fill a position, so it was a pleasant surprise.
