We are seeking a highly skilled Security Engineer to help architect, implement, and defend our cybersecurity infrastructure. This is a hands‑on technical role focused on protecting us from sophisticated cyber threats.

The ideal candidate will bring experience securing highly regulated, mission‑critical environments and possess a strong understanding of both Information Technology (IT) and Operational Technology (OT) security. This individual will play a key role in designing and maintaining a resilient security posture across enterprise and industrial control environments.

• Design, implement, and maintain cybersecurity solutions and programs across enterprise and operational technology environments.
• Modernize legacy security infrastructure and support the transition to a hardened, security‑first architecture.
• Evaluate, deploy, and optimize security technologies including endpoint protection, network security, identity management, product security, and monitoring solutions.
• Support the implementation of Zero Trust principles across systems and networks.
• Secure the convergence of Information Technology (IT) and Operational Technology (OT) environments.
• Implement security controls for Industrial Control Systems (ICS), SCADA networks, and other critical operational technologies.
• Conduct vulnerability assessments, risk analysis, and vulnerability tests within industrial environments while maintaining operational reliability.
• Support network segmentation, access control, and secure remote access strategies for operational systems.

• Assist in maintaining compliance with applicable cybersecurity regulations and frameworks, including NIST SP 800-53, NRC requirements, and other critical infrastructure standards.
• Perform security assessments, control validation, and documentation activities.
• Support audits and regulatory reviews by providing technical evidence and remediation plans.
• Participate in enterprise risk assessments and mitigation planning.
