Senior Cybersecurity Engineer

Senior Cybersecurity Engineer | Carrollton, TX

100% On-Site | Contract-to-Hire | ~20% Travel | Pay Rate: $55 to $70/ hourly

We’re hiring a Senior Cybersecurity Engineer for a hands-on engineering role supporting customized systems used in critical infrastructure environments, including nuclear power facilities.

This is not a traditional SOC or corporate security monitoring position. We’re looking for an engineer who can work across cybersecurity, Windows infrastructure, networking, virtualization, and system hardening, while owning the cybersecurity portion of projects from initial requirements and design through implementation, testing, deployment, and customer turnover.

What You’ll Do

• Serve as the cybersecurity technical lead on multidisciplinary engineering projects.

• Own cybersecurity deliverables throughout the full project lifecycle.

• Design, configure, secure, and troubleshoot Windows Server and Active Directory environments.

• Configure and manage Group Policy/GPO, VMware/virtualization, switches, firewalls, IDS/IPS, storage, and other infrastructure technologies.

• Perform system hardening, vulnerability scanning, patch management, security assessments, and log analysis.

• Troubleshoot complex infrastructure, networking, and security integration issues.

• Participate in system testing, customer acceptance testing, onsite deployment, and system turn-up.

• Work directly with customers to understand requirements, evaluate technical requests, and recommend solutions.

• Develop technical documentation and support customer training and system turnover.

• Collaborate closely with software, hardware, testing, technical writing, project engineering, and project management teams.

What We’re Looking For

• Bachelor’s degree in Cybersecurity, Computer Science, Systems Engineering, Computer Engineering, IT, or a related technical discipline.

• Strong hands-on cybersecurity, systems engineering, infrastructure security, or similar experience.

• Strong experience with:

  • Windows Server

  • Active Directory

  • Group Policy / GPO

  • VMware / virtualization

  • Networking and switch configuration

  • Firewalls and IDS/IPS

  • System hardening

  • Vulnerability management

  • Log analysis and troubleshooting

• Ability to independently investigate and solve complex technical problems.

• Strong written and verbal communication skills.

• Comfortable working directly with customers and technical stakeholders.

• Ability to take ownership, adapt to shifting project priorities, and work effectively across engineering teams.

• Willingness to work onsite in Carrollton, TX five days per week.

• Ability to travel approximately 20%, including occasional trips lasting 1–2 weeks.

• U.S. citizenship required.

Nice to Have

• Experience with nuclear, critical infrastructure, industrial/OT, defense, government, or other highly regulated environments.

• Strong network engineering or network architecture background.

• Splunk and/or Trellix experience.

• Experience with CIS Benchmarks, patch management, vulnerability assessments, or NEI 08-09.

• Familiarity with cybersecurity frameworks applicable to critical infrastructure, including NIST SP 800-82, NIST SP 800-53, IEC 62443, or NRC cybersecurity requirements.

• CISSP, Security+, GICSP, CASP+, or similar certification.

Why This Role?

If you enjoy being hands-on and want more ownership than a traditional cybersecurity role provides, this is an opportunity to work on complex systems where security, infrastructure, networking, and engineering all come together.

You’ll have the opportunity to follow solutions from requirements and design through hands-on implementation, testing, onsite deployment, and customer turnover, while working alongside a collaborative multidisciplinary engineering team.
