Systems Security Engineer Jobs in Texas: Frequently Asked Questions
How do you become a systems security engineer in Texas?
The most direct path is earning a bachelor's degree in cybersecurity, computer science, or information systems, then obtaining a widely recognized certification such as CompTIA Security+, CISSP, or CEH. Texas does not require a state-issued license specific to systems security engineering, but many employers in defense and government contracting require candidates to obtain or be eligible for a federal security clearance before starting. Building hands-on experience through internships, home labs, or adjacent IT roles strengthens applications considerably.
How much do systems security engineers make in Texas?
Systems security engineers in Texas earn a median of about $111,530 a year, based on May 2025 Bureau of Labor Statistics wage data, ranging from around $55,480 for the lowest 10% to over $174,300 for the top 10%. Pay rises with experience, specialty, and employer.
Which companies hire systems security engineers in Texas?
Employers hiring systems security engineers in Texas right now include Lockheed Martin, Digi Security Systems, and D.H. Pace Company, based on current listings on Migrate Mate as of November 2026. Texas's mix of defense contractors, large financial institutions, and enterprise technology companies means demand is spread across several distinct employer types rather than concentrated in a single sector.
Which Texas cities have the most systems security engineer jobs?
Austin, Houston, and Dallas have the most systems security engineer openings in Texas. Austin's large technology employer base drives volume there, Dallas attracts financial services and enterprise IT firms, and San Antonio's concentration of military installations and defense contractors, including Joint Base San Antonio, creates sustained demand for cleared and clearance-eligible engineers.
Are there remote systems security engineer jobs in Texas?
Yes, and more than most technical fields, since systems security engineering work is largely analytical, software-based, and executable from any secure connection. About 25% of systems security engineer openings tied to Texas are remote or hybrid as of November 2026, though roles that require handling classified systems or on-site incident response are typically on-site only. Cloud security, compliance, and threat intelligence positions are the most consistently remote-eligible.
How can I get hired as a systems security engineer in Texas with little or no experience?
The most realistic entry path is moving from an adjacent IT role such as network administrator, systems administrator, or help desk analyst into a junior security analyst or associate security engineer position. Large Texas employers including USAA, Raytheon, and state agencies through the Texas Department of Information Resources hire for entry-level security operations roles and sometimes run structured rotational or apprenticeship programs. Earning CompTIA Security+ before applying gives candidates a concrete, employer-recognized credential that offsets limited professional experience.
Where can I find and apply to systems security engineer jobs in Texas?
You can find and apply to systems security engineer jobs in Texas on Migrate Mate, which lists current Texas openings from employers actively hiring right now. Search the listings, find roles that match your experience and location, and apply directly to the ones that fit.
