Responsibilities

We are seeking a highly skilled and innovative ICS Cybersecurity Engineer/Segmentation/RA to join our team in the greater DMV area, supporting the Army National Guard.

Responsibilities

• Design secure segmentation architectures for ICS/OT environments using zoning, conduits, and access‑control strategies aligned with IEC 62443 and NIST SP 800‑82.
• Conduct risk assessments evaluating exposure, safety impacts, threat vectors, and potential operational consequences for industrial control systems.
• Develop mitigation strategies, firewall/ACL policies, network isolation controls, and secure remote access designs to reduce lateral movement and operational disruption.
• Create and validate segmentation diagrams, data‑flow models, and conduit definitions to support secure integration of ICS/OT with enterprise networks.
• Produce remediation roadmaps, technical risk reports, and prioritized POA&Ms that support resilience and regulatory/compliance requirements.
• Coordinate with control system engineers, network teams, SOC/CIRT, and safety stakeholders to validate designs and minimize safety/availability impacts.
• Oversee testing and validation of segmentation controls (risk acceptance tests, functional verification, failover behavior) in lab and production staging environments.
• Maintain configuration/change records, evidence for audits, and documentation supporting accreditation and continuous monitoring.
• Mentor engineering teams on ICS security best practices and integration of segmentation into lifecycle processes.
