Active TS/SCI clearance.
Bachelor’s degree in Computer Science, Cybersecurity, Data Science, Information Systems, Information Technology, Software Engineering, or a related field; OR Relevant DoD/military training (examples: DAF 462 (Intermediate) (ICS); DAF 462 (Intermediate) (CS3‑300)); OR Relevant professional certification or equivalent experience (Certification: Pending Review).
OT/ICS cybersecurity, network engineering, or control‑systems experience with at least 5+ years leading OT security efforts in industrial or DoD environments.
Deep expertise in OT protocols, device architectures, segmentation/zoning, secure remote access, and safety‑aware security measures.
Proven ability to design and validate OT detection use cases, run OT‑specific telemetry analysis, and translate findings into mitigations and POA&Ms.
Experience leading OT incident response, forensic collection in industrial environments, and coordinating cross‑functional containment/remediation.
Strong technical writing and briefing skills for decision‑grade technical reports and executive summaries.

Nice To Haves

Prior DoD/ARNG/critical‑infrastructure OT cybersecurity experience.
Professional certs (preferred): CISSP; CompTIA CASP+ (CASP+ CE).
Familiarity with OT monitoring platforms, protocol analyzers, and integration of OT telemetry into SOC/CIRT toolchains.

Responsibilities

Design, implement, and evaluate OT security controls across ICS, SCADA, DCS, PLCs, and other mission‑critical OT environments.
Develop OT security architectures, segmentation strategies, and hardening baselines aligned with NIST SP 800‑82, ISA/IEC 62443, DoD, and Army requirements.
Analyze OT network traffic, device configurations, and protocol behavior to identify security gaps, operational risks, and adversary activity.
Define high‑value OT log sources, detection use cases, and behavioral analytics to inform monitoring and detection engineering.
Oversee vulnerability assessments, OT risk evaluations, and red/blue‑team validation exercises to assess defensive resilience.
Coordinate cross‑team integration with SOC, CIRT, engineering, facilities, RCC‑ARNG, NETCOM, and ARCYBER to align OT cybersecurity with mission needs.
Lead OT incident response: forensic collection, impact assessment, containment, remediation, and system restoration activities.
Produce technical reports, architectural recommendations, POA&Ms, and executive briefings to inform enterprise modernization and risk decisions.
Drive continuous improvement by evaluating emerging OT security technologies, updating baselines, and refining operational workflows for safety and mission readiness.
