Overview

The OT Cyber Security Analyst is a critical member of the Cybersecurity and Operational Technology (OT) team, responsible for securing industrial control systems and manufacturing environments. This role focuses on OT security monitoring, threat detection and incident response, vulnerability management, and secure implementation of cybersecurity controls across plant operations.

The analyst will leverage hands-on experience in manufacturing environments, working directly with PLCs, embedded systems, industrial networks, and OT-specific security platforms such as Dragos, alongside tools including Crowd Strike and Linux-based systems. This role requires a practitioner who can bridge IT and OT domains, ensuring the availability, integrity, and security of production systems without disrupting operations.

This is a remote position with travel required to manufacturing facilities primarily in North America, with occasional travel to Europe and South America.

• OT Security Monitoring & Incident Response: Monitor industrial networks, control systems (SCADA, PLCs), and plant environments for cyber threats and anomalies. Investigate alerts generated by tools such as Dragos and Crowd Strike
  , and coordinate incident response actions including containment and recovery with plant operations teams.
• Threat Detection & OT Risk Analysis: Identify threats targeting industrial control systems by analyzing OT network traffic, device behavior, and threat intelligence. Perform root cause analysis of incidents impacting manufacturing environments.
• OT Vulnerability Management: Assess vulnerabilities across OT assets including PLCs, HMIs, and embedded systems. Partner with engineering and plant teams to prioritize remediation activities that minimize production risk.
• Industrial Control Systems (ICS) Security: Support the design, implementation, and maintenance of secure architectures for PLCs, DCS, and embedded systems
  . Ensure adherence to segmentation, least privilege access, and secure communication protocols within plant environments.
• Tool Administration & Optimization: Deploy, maintain, and optimize OT and endpoint security platforms including Dragos, Crowd Strike, and Linux-based monitoring tools
  . Tune detection rules and alerts to reduce false positives and improve threat visibility.
