Operational Technology (OT) Security Analyst / ICS Penetration T with Security Clearance

Job Description  We are seeking a highly skilled Operational Technology (OT) Security Analyst to evaluate, attack, and strengthen the security posture of our critical industrial control systems (ICS).

• Vulnerability Testing: Conduct active and passive security assessments on OT environments, including SCADA, PLCs, RTUs, and HMI systems.
• Protocol Analysis: Analyze and test proprietary and open industrial protocols (e.g., Modbus, DNP3, Ethernet/IP, PROFINET, BACnet).
• Architectural Review: Evaluate network segmentation designs (Purdue Model) and identify unauthorized IT-to-OT bridging.
• Risk Mitigation: Deliver clear, actionable remediation reports to both highly technical engineering teams and non-technical plant managers.
• Safety First Execution: Design customized, non-disruptive testing methodologies specifically tailored to avoid triggering physical system failures or emergency shutdowns .

Basic Qualifications Security Clearance: Active TS/SCI   Education: Bachelor's degree in Information Technology, Computer Science, Cybersecurity, Information Systems, Engineering, or related discipline. Equivalent experience may be substituted.

Certification: Candidate must meet applicable IAT II certification requirements (ex: Security+).
