Cyber Security Subject Matter Expert

Industrial / Nuclear-Regulated Environment | Confidential U.S. Megaproject

I'm seeking a Cybersecurity Subject Matter Expert to lead the end-to-end cybersecurity architecture for a next-generation, highly regulated facility.

This role will define, implement, and sustain cybersecurity across enterprise IT, industrial control systems (ICS), operational technology (OT), and digital instrumentation environments within a safety-critical setting.

This is not a support function. This is technical authority.

• Define and maintain reference architecture across IT, OT, and ICs environments
• Lead network segmentation strategy including zones, conduits, and high-assurance data boundaries
• Develop system security requirements for plant systems and digital control infrastructure
• Ensure secure integration of vendor systems and EPC-delivered platforms
• Design and oversee SOC capabilities tailored to industrial environments
• Implement continuous monitoring across both enterprise and plant networks
• Develop incident response frameworks aligned with safety and regulatory requirements

• Establish risk-based vulnerability and patch management strategies compatible with high-availability systems
• Conduct threat modeling for safety-critical environments
• Oversee security assessments and supply chain risk reviews

• Lead alignment with federal cybersecurity frameworks and nuclear-grade regulatory requirements
• Develop and maintain cybersecurity plans, policies, and audit documentation
• Support regulatory inspections and long-term sustainment governance

• Deep experience securing industrial control systems in regulated industries
• Strong understanding of ICs segmentation, secure architecture, and high-availability constraints
• Strong understanding of NIST cybersecurity frameworks & NRC/DOE standards and regulations
• Experience interfacing with engineering, I&C, EPC contractors, and regulatory stakeholders
• Background in nuclear, energy, utilities, or other safety-critical infrastructure strongly preferred

This is a rare opportunity to design cybersecurity architecture from the ground up for a mission-critical U.S. facility.

If this sounds like you and piques your interest, don't hesitate to apply to this job posting or reach out to me directly penter and I'll be in touch promptly.
