Application Security Engineer Jobs in Texas: Frequently Asked Questions
How do you become an application security engineer in Texas?
Application security engineering has no state-issued license in Texas, so the path runs through education and industry credentials. Most Texas employers expect a bachelor's degree in computer science, information security, or software engineering, followed by certifications such as CISSP, CEH, or CSSLP. Candidates who build hands-on experience through capture-the-flag competitions, open-source contributions, or an AppSec-focused internship at a Texas technology firm move into roles most quickly.
How much do application security engineers make in Texas?
Application security engineers in Texas earn a median of about $132,150 a year, based on May 2025 Bureau of Labor Statistics wage data, ranging from around $82,600 for the lowest 10% to over $183,680 for the top 10%. Pay rises with experience, specialty, and employer.
Which companies hire application security engineers in Texas?
Employers hiring application security engineers in Texas right now include Amazon, AbbVie, and ServiceLink, based on current listings on Migrate Mate as of November 2026. Texas's deep mix of defense contractors, financial institutions, and enterprise software companies means demand is spread across multiple sectors rather than concentrated in a single industry.
Which Texas cities have the most application security engineer jobs?
Austin, Plano, and Dallas account for the most application security engineer openings in Texas. Austin's dense concentration of technology companies and corporate headquarters drives the largest share of listings, while Dallas's financial services sector and San Antonio's significant defense and federal contracting base each sustain strong ongoing demand for application security talent.
Are there remote application security engineer jobs in Texas?
Yes, and more than most fields. About 100% of application security engineer openings tied to Texas are remote or hybrid as of November 2026, reflecting how naturally this work translates to distributed teams. Code review, vulnerability assessment, and security tooling integration are the functions most commonly performed fully remotely, while red-team engagements and regulated-environment work tend to require on-site presence.
How can I get hired as an application security engineer in Texas with little or no experience?
The most realistic entry path is moving laterally from a software development or IT operations role where you already touch code or infrastructure. Large Texas employers such as Dell, USAA, and major regional health systems recruit associate-level security analysts who transition into application security with mentorship. Building a portfolio through bug bounty programs, contributing to open-source security tooling, and earning the CompTIA Security+ or eJPT certification gives candidates without formal AppSec experience a concrete edge in Texas hiring pipelines.
Where can I find and apply to application security engineer jobs in Texas?
You can find and apply to application security engineer jobs in Texas on Migrate Mate, which lists current openings across the state. Find roles that fit your experience and target location, then apply directly to the employers posting them.
