• Develop secure network segmentation, vendor remote access, monitoring, and control strategies that reduce cyber risk while supporting operational reliability.
• Troubleshoot and resolve technical issues involving vendor access, network communications, firewall policies, and cybersecurity controls in manufacturing environments.
• Support engineering, maintenance, operations, site technology teams, and vendors during cybersecurity implementations, remediations, and incident response activities.
• Lead cybersecurity improvement initiatives across manufacturing sites, including secure access, network modernization, monitoring, and risk reduction projects.
• Assess cybersecurity risks affecting manufacturing systems and help prioritize remediation based on business impact, safety, reliability, and exposure.
• Create technical documentation, network diagrams, standards, implementation guidance, and troubleshooting procedures for operational technology environments.
• Partner with cross-functional teams to embed cybersecurity into the lifecycle of manufacturing systems, from design and deployment through ongoing operations.
• Collaborate with security operations teams to improve monitoring, escalation,…
