Senior Engineer, Cybersecurity Engineering / Onsite - Carrollton, TX /
Contract to hire

Our client is a global leader in radiation safety, measurement, and critical infrastructure command-and-control solutions, that's based out of Carrollton, TX.

If you are an engineer who thrives at the intersection of cybersecurity, systems engineering, and mission-critical physical infrastructure, this role offers true cradle-to-grave project ownership. Rather than sitting in a passive security operations center monitoring dashboard alerts, you will architect, build, harden, and personally commission secure command-and-control (C2) platforms that protect commercial nuclear power facilities and national critical infrastructure against sophisticated real-world threats. You will own the full systems lifecycle using disciplined V-Model engineering, from translating customer cyber requirements and locking down 20-30 node Active Directory clusters to conducting live Site Acceptance Testing (SAT) on location. This is an exceptional growth opportunity for a hands-on builder seeking high-visibility engineering impact in an essential, highly resilient industry.

Required Skills & Experience

• 5 to 7 years of hands-on experience in cybersecurity systems engineering with end-to-end project ownership.
• Proven track record building, configuring, and hardening environments of 20-30 Windows servers and workstations within an Active Directory domain utilizing Group Policy (GPO) and CIS Benchmarks.
• Direct experience deploying and configuring virtualized server clusters, storage architectures, Linux-based appliances, network switches, and firewalls.
• Demonstrated familiarity with formal systems engineering frameworks (Standard V-Model) and managing requirements via Requirements Traceability Matrices (RTM).
• Hands-on experience developing and executing cybersecurity verification procedures, vulnerability assessments, security scanning, and finding dispositions.
• Bachelor's degree in Cybersecurity, Systems Engineering, Computer Science, Electrical Engineering, Information Technology, or a related discipline.
• Willingness and ability to travel up to 25% for physical installation, commissioning, and client turnover at customer sites.
• U.S. Citizenship or Permanent Resident status required, with the ability to obtain unescorted site access credentials at commercial nuclear power plants and government facilities.

Desired Skills & Experience

• Prior experience delivering systems in commercial nuclear power, defense, or NRC/DOE/DOD-regulated environments, including familiarity with NRC 10 CFR 73.54 and NEI 08-09 compliance frameworks.
• Working knowledge of industrial and critical infrastructure cybersecurity standards such as NIST SP 800-82, NIST SP 800-53, or IEC 62443.
• Background integrating physical security subsystems (access control, surveillance, monitoring) with command-and-control software.
• Professional certifications such as GICSP, CISSP, CASP+, or CompTIA Security+.
• Polished customer-facing technical communication skills with experience running formal Factory or Site Acceptance Testing (FAT/SAT).
