The OT Network & Security Engineer II implements, operates, and supports secure, resilient network infrastructure and cybersecurity controls across operational technology environments.

The engineer partners with SCADA, field operations, infrastructure, vendors, and OT Cybersecurity to maintain reliable connectivity and implement approved security controls. OT experience is preferred but not required; strong enterprise networking or network security experience with exposure to industrial or operational environments is acceptable.

The role focuses on hands‑on implementation and support, while cybersecurity architecture, governance, policy, formal risk acceptance, and regulatory interpretation remain with the appropriate cybersecurity and governance teams.

• Configure, maintain, and troubleshoot switches, routers, firewalls, VPNs, and related network infrastructure to ensure secure and reliable connectivity across operational sites
• Support routing, VLANs, network segmentation, firewall policies, and secure remote access by analyzing technical requirements and implementing approved configurations
• Monitor network performance, device health, logs, and security events to identify issues, determine root cause, and support timely resolution
• Troubleshoot network, firewall, VPN, segmentation, and application connectivity issues using structured analysis, diagnostic tools, and operational data
• Implement approved firewall rules, security profiles, and access controls to support least‑privilege access and reduce operational security risk
• Perform firmware upgrades, patching, hardening, and vulnerability remediation to maintain supported, secure, and compliant network infrastructure
• Support network and cybersecurity incident response by analyzing events, identifying contributing factors, and implementing corrective actions
• Execute network and security changes through established change‑management processes, including impact analysis, testing, validation, documentation, and rollback planning
• Support commissioning, expansion, and technology refresh activities by integrating network and security infrastructure into new and existing operational sites
• Maintain accurate network diagrams, configuration records, IP addressing, firewall documentation, and equipment inventories to support operations, troubleshooting, and audit requirements
• Collaborate with SCADA, field operations, infrastructure, vendors, and OT Cybersecurity teams to translate operational and security requirements into reliable technical solutions
• Identify opportunities to improve reliability, security, monitoring, automation, and standardization by analyzing recurring issues, operational trends, and technical performance

• Bachelor’s degree in Computer Science, Information Technology, Cybersecurity, or a related discipline; or an equivalent combination of education, technical training, industry certifications, and relevant professional experience
• Candidates should demonstrate relevant hands‑on experience, formal training, or industry certification. Certifications are preferred but may be substituted with equivalent technical knowledge and practical experience
• Minimum 3years of experience in network engineering, network security, infrastructure, telecommunications, or related technologies
• Experience supporting distributed, remote, industrial, utility, manufacturing, or operational environments preferred
• OT, SCADA, or ICScience experience preferred but not required; strong enterprise networking or security experience with demonstrated ability to learn OT environments will be considered
