Responsibilities

Provides technical leadership for OT network security strategy, architecture, standards, and roadmap development across operational environments, including distribution centers, automation platforms, industrial control systems, IoT/IoT devices, facilities systems, and supporting network infrastructure.
Designs and leads implementation of secure OT network architectures using principles such as Purdue Model segmentation, zero trust, defense-in-depth, secure zones and conduits, least privilege, and controlled connectivity between IT, OT, cloud, and vendor-managed environments.
Plans and leads upgrades to OT network security measures and tools to protect operational systems, networks, and connected assets while minimizing disruption to safety, quality, availability, and business operations.
Analyzes trends, threat intelligence, vulnerabilities, regulatory expectations, and changes in the OT and industrial cybersecurity landscape; advises leadership on organizational risk and recommends mitigation strategies.
Develops, refines, and implements OT security policies, standards, procedures, reference architectures, and technical patterns aligned to frameworks such as ISA/IEC 62443, NIST SP 800-82, NIST Cybersecurity Framework, ISO 27001, and applicable compliance requirements.
Leads OT network segmentation initiatives, including firewall rule governance, access control, network access control, secure routing, remote access hardening, jump host architecture, micro-segmentation, and monitoring of traffic between IT and OT environments.
Partners with network administrators, system administrators, facilities teams, automation engineers, and third-party vendors to ensure OT networks, servers, endpoints, controllers, network devices, and security technologies conform to approved security standards.
Provides technical guidance for OT asset discovery, inventory management, vulnerability management, configuration baselines, patch risk assessment, compensating controls, and lifecycle planning for systems with operational or vendor constraints.
Contributes to response activities for OT security incidents, including triage, investigation, containment, eradication, recovery, root cause analysis, lessons learned, and coordination with enterprise incident response teams and third-party responders.
Formulates methodologies to monitor, detect, analyze, and respond to OT network security events; supports the integration of OT telemetry into SIEM, SOAR, network detection and response, vulnerability management, and enterprise cyber operations processes.
Provides technical oversight for security controls in the acquisition, design, development, change management, and deployment lifecycle for OT systems, warehouse automation technologies, network-connected equipment, and third-party-managed platforms.
Reviews technical and functional design documents, network diagrams, firewall requests, connectivity patterns, vendor proposals, and implementation plans to identify security risks and recommend practical remediation actions.
Coordinates with senior technical leaders across Information Security, Infrastructure, Network Engineering, Cloud, Facilities, Distribution Operations, and Enterprise Architecture to design and implement resilient security solutions that protect physical and intangible assets.
Provides technical guidance, coaching, and mentorship to engineers and analysts supporting OT security, network security, cyber operations, vulnerability management, and incident response activities.
Maintains and contributes to service-level expectations, operational procedures, and governance processes to ensure OT security controls remain effective, measurable, and supportable.
Communicates advanced OT and information security concepts clearly to technical teams, business leaders, vendors, auditors, and executive stakeholders.
Develops metrics, KPIs, risk insights, remediation progress, and executive-level summaries related to OT network security posture.
Researches, evaluates, and supports deployment of security technologies for OT and industrial environments, including industrial network monitoring, firewalls, secure remote access, network detection and response, asset discovery, vulnerability management, identity and access management, email security, endpoint controls, SIEM, SOAR, and cloud-connected OT security use cases.
