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 CrowdStrike 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 CrowdStrike, 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, CrowdStrike, and Linux-based monitoring tools. Tune detection rules and alerts to reduce false positives and improve threat visibility.
• Network Segmentation & Plant Security Controls: Assist in implementing network segmentation strategies between IT and OT environments. Validate firewall rules, remote access controls, and secure vendor connectivity into plant networks.
• Collaboration with Manufacturing & Engineering Teams: Work closely with plant managers, controls engineers, and IT teams to integrate cybersecurity controls into manufacturing processes without impacting uptime or throughput.
• Security Policy, Compliance & Standards: Ensure OT security practices align with frameworks such as NIST Cybersecurity Framework (CSF), ISA/IEC 62443, and internal company cybersecurity policies. Support audits and risk assessments specific to manufacturing operations.
• Continuous Improvement & Threat Intelligence: Stay current on emerging OT threats and vulnerabilities. Contribute to improving the organization’s overall OT security posture through new controls, tools, and best practices.

• Work Environment & Travel Requirements

  • Remote-based role with expected travel:
  • North America manufacturing sites: primary travel (approximately 50%)
  • International travel (Europe & South America): occasional, project-based
