* Summary:

** The Operational Technology Network Security Engineer III is responsible for designing, implementing, maintaining, and improving security controls across operational technology, industrial control systems, and network environments. This role supports the protection of distribution, automation, facilities, warehouse, and other critical operational environments by applying cybersecurity best practices to OT networks, connected systems, and supporting infrastructure. The engineer partners with Information Security, Infrastructure, Operations, Engineering, Facilities, and business stakeholders to assess risk, strengthen network segmentation, monitor threats, support incident response, and ensure OT environments remain secure, resilient, and aligned with enterprise standards.
** Primary Responsibilities****:
*** Designs, implements, and supports security controls for operational technology networks, industrial control systems, manufacturing systems, warehouse automation platforms, building management systems, and related connected environments.
* Assesses OT and ICS network architectures to identify risks, security weaknesses, segmentation gaps, insecure protocols, and opportunities to improve resilience and defense in depth.
* Partners with network engineering, infrastructure, operations, facilities, manufacturing, warehouse automation, and cybersecurity teams to implement secure network designs, firewall policies, access controls, and remote access solutions for OT environments.
* Supports development and maintenance of OT network security standards, procedures, reference architectures, and operational playbooks aligned to enterprise security requirements and relevant frameworks.
* Conducts & supports vulnerability, configuration, and risk assessments for OT assets, network devices, firewalls, remote access tools, and connected industrial systems while considering operational availability and safety requirements.
* Coordinates remediation planning with technical and business teams, balancing security risk reduction with operational continuity, safety, regulatory, and business constraints.
* Monitors OT security alerts, network activity, and threat intelligence to detect suspicious behavior, unauthorized access, policy violations, and indicators of compromise in OT environments.
* Supports incident response activities impacting OT networks and connected systems, including containment planning, evidence gathering, root cause analysis, recovery support, and post-incident recommendations.
* Implements and maintains security technologies that may include OT network monitoring, firewalls, IDS/IPS, NAC, SIEM integrations, remote access platforms, vulnerability management tools, and endpoint or asset visibility solutions.
* Reviews technical designs and change requests for OT network infrastructure to ensure security requirements are incorporated before implementation.
* Works closely with Information Security and line-of-business management to identify, formulate, and implement practical security solutions and controls for OT and industrial environments.
* Coordinates with systems, network, cloud, and security engineers to ensure OT-connected infrastructure conforms to security standards and that security devices and controls are operating as intended.
* Gathers and analyzes reporting, metrics, and key performance indicators related to OT network security posture, control effectiveness, vulnerabilities, remediation status, and operational risk.
