Position Summary:

The OT Cybersecurity Analyst supports the protection and resilience of critical infrastructure environments through threat intelligence analysis, security monitoring, incident response, and vulnerability assessment activities focused on Operational Technology (OT) and Industrial Control Systems (ICS). This role is responsible for identifying and analyzing cyber threats targeting industrial environments, supporting incident response efforts, and helping clients strengthen the security posture of mission-critical systems across sectors such as energy, water, transportation, and manufacturing.

The position works closely with clients, government partners, and internal technical teams to provide actionable intelligence, risk-based recommendations, and regulatory compliance support. Successful candidates will bring a strong understanding of OT/ICS environments, evolving cyber threats, and the operational considerations required to secure critical infrastructure systems.

Essential Functions:

Threat Intelligence & Analysis

* Monitor, collect, and analyze cyber threat intelligence from open-source, commercial, and government feeds (ISACs, CISA, sector-specific advisories) with specific focus on threats targeting critical infrastructure sectors (energy, water, transportation, manufacturing)

* Assess threat actor TTPs (Tactics, Techniques, and Procedures) relevant to ICS/SCADA environments using frameworks such as MITRE ATT&CK for ICS and the Purdue Model

* Produce timely, actionable threat intelligence reports tailored to both technical and executive audiences

OT/ICS Security Monitoring

* Perform continuous monitoring of OT/ICS network environments, including SCADA systems, PLCs, RTUs, HMIs, and historian servers, for anomalous or malicious activity

* Analyze network traffic, asset telemetry, and security events across IT/OT boundaries using OT-aware tools (e.g., Claroty, Dragos, Nozomi Networks, Tenable OT)

* Identify and document Indicators of Compromise (IoCs) and Indicators of Attack (IoAs) specific to industrial control system environments

Incident Detection, Response & Support

* Triage, investigate, and escalate security incidents in accordance with client incident response plans and sector-specific regulatory requirements

* Support containment, eradication, and recovery activities for cyber incidents affecting OT/ICS environments, with acute awareness of operational safety and uptime constraints

* Maintain detailed incident timelines, chain-of-custody documentation, and post-incident lessons-learned reports

Vulnerability & Risk Assessment

* Conduct vulnerability assessments of OT assets, applying risk-based prioritization that accounts for operational impact, compensating controls, and the consequences of patching in live industrial environments

* Map identified vulnerabilities to threat actor capabilities and likelihood of exploitation to support client risk decisions

* Track remediation efforts and validate closure of identified findings

* Client Engagement & Reporting

* Serve as a day-to-day technical point of contact for assigned clients, delivering regular briefings on threat landscape changes, incident status, and security posture

* Develop and maintain client-specific threat profiles, asset inventories, and sector risk assessments

* Communicate findings clearly and professionally across technical, operational, and executive stakeholder levels

Regulatory & Standards Compliance Support

* Support clients in understanding and meeting cybersecurity obligations under relevant frameworks and regulations, including NERC CIP, NIST SP 800-82, IEC 62443, TSA Security Directives, and AWIA 2018,…
