• Analyze communications between OT networks, corporate IT environments, and other network zones to identify security risks.
• Identify cybersecurity gaps and develop remediation recommendations based on risk, implementation effort, and resource requirements.
• Implement and validate ISA/IEC 62443-3-3 controls and document the Security Level achieved for operationalized controls.
• Support technical deployments involving core switches, OT threat-detection technologies, network infrastructure, cabling, and other cybersecurity controls.
• Develop deployment plans in partnership with site leadership, technical teams, strategic partners, and service providers.
• Coordinate deployment prerequisites, technical resources, schedules, change requirements, production downtime, and operational considerations.
• Drive cybersecurity deployments across multiple sites, vendors, and service providers.
• Obtain quotes from strategic partners and service providers for cybersecurity controls and deployment activities.
• Support budget planning, forecasting, deployment schedules, and project tracking.
• Participate in recurring deployment and risk-management meetings and provide status updates to key stakeholders.

Required Qualifications

• 10+ years of relevant cybersecurity experience, including significant experience within OT, ICS, industrial, or manufacturing environments.
• Strong hands-on experience implementing ISA/IEC 62443-3-3 security controls.
• Mastery-level understanding of ISA/IEC 62443 standards and security requirements.
• Experience conducting cybersecurity assessments of manufacturing plants, industrial facilities, or comparable OT environments.
• Strong understanding of OT network architecture, including industrial network segmentation and the Purdue Model.
• Experience evaluating communications and security boundaries between IT and OT environments.
• Strong technical skills configuring and integrating cybersecurity tools and controls into OT networks.
• Experience supporting the remediation of OT cybersecurity risks and control deficiencies.
• Strong understanding of cybersecurity risks, threats, vulnerabilities, and their potential impact on industrial operations.
• Experience coordinating technical deployments involving multiple teams, site personnel, strategic partners, and service providers.
• Strong project management, analytical, collaboration, negotiation, written, and verbal communication skills.
