Operational Technology Network Analyst Senior
Job Details:
This position is responsible for the administration and monitoring of next-generation firewalls, Security Information and Event Management (SIEM) systems, Intrusion Detection/Prevention Systems (IDS/IPS), and OT network components within critical utility environments. The ideal candidate will have hands-on experience with OT security tools and protocols, an understanding of Purdue model segmentation, and the ability to work collaboratively with IT and compliance teams to ensure secure and resilient operations. This role supports the protection of OT systems, regulatory compliance, and the overall cybersecurity posture of the utility’s OT infrastructure.
Summary This position performs advanced, complex technical and analytical work to support a robust multi-facility SmartGrid environment. Work is performed on-site and off-site in a secure, monitored environment 24/7/365. This role supports the reliability, cybersecurity, and regulatory compliance of the bulk electric system, real-time operational systems including SCADA, ICCP, virtualization, and secure communication paths necessary to deliver energy services. It requires expert knowledge in network engineering, system administration and cybersecurity within an energy utility or critical infrastructure environment, and involves leading high-impact projects to improve system resilience and adherence to NERC CIP, NIST and other industry standards while working with minimal supervision.
Essential Job Functions
Design, implement, and optimize high-availability network architecture (LAN, WAN, VLAN, SD-WAN, and wireless), firewalls, VPNs, IDS/IPS, and segmentation strategies to secure OT environments and maintain real-time communications.
Communicate network security policies and procedures required for regulatory compliance to end users, control room operators and remote facility staff.
Design, install, configure, administer, monitor and optimize server infrastructure, including redundant and highly available virtualized environments, cloud-based solutions, Windows and Linux servers, databases, and storage supporting SCADA and other OT applications in a CIP environment.
Create, maintain, remove and audit physical and electronic access to NERC CIP environments.
Utilize regulatory and industry standards (NERC CIP, NIST 800-53, DOE C2M2) to identify capabilities and technologies needed to provide enhanced cyber defenses.
Conduct penetration tests, vulnerability scans, risk assessments, and regular audits to protect OT assets and provide mitigation recommendations.
Lead the development, execution and testing of incident response, disaster recovery and business continuity plans; provide SME support during cyber incidents, response and remediation.
Work closely with System Control, SCADA Engineers, IT Security, and external vendors to implement secure, scalable solutions.
Develop and follow processes for network change management, configuration control, preventative maintenance, and access control in line with GRU policies and CIP requirements.
Participate in OT feasibility studies, capacity planning, performance analysis and requirements reviews for new systems and applications.
Non-essential Job Functions
Conduct research on emerging products, services, protocols, and standards to support procurement and development efforts.
Perform cost-benefit analyses for proposed network components.
Other related duties as assigned; attend required training; maintain regular attendance; may travel to remote locations.
