Hey there. I also moved to TX 2 years ago, right after I graduated from college. I would recommend going for the smaller schools listed here: https://www.atssb.org/job-board/job-vacancy-board/

You can also check out ESC regions for specific areas. Sometimes, districts only post there. https://tea.texas.gov/about-tea/other-services/education-service-centers/education-service-centers-map Some regions have a centralized application system, and others do not.
