The opportunity:

The Lead Operational Technology Cybersecurity Engineer is a senior technical role responsible for helping secure the systems, networks, and technologies that support Smurfit Westrock\u2019s manufacturing operations. This position plays a critical role in protecting plant environments while ensuring that cybersecurity controls support, rather than disrupting, safety, reliability, and production.

In this role, you will work closely with cybersecurity, engineering, maintenance, operations, and vendor teams to design and implement practical security solutions for manufacturing environments. You will help secure industrial networks, improve vendor remote access, support network segmentation efforts, troubleshoot technical issues, and guide sites through cybersecurity improvements.

A typical day may include reviewing a new vendor remote access request, troubleshooting a firewall or connectivity issue with a manufacturing site, helping design secure network segmentation for production systems, documenting a technical standard, supporting a risk remediation plan, or advising operations and engineering teams on how to implement cybersecurity controls without impacting plant uptime.

This role requires someone who can combine deep technical cybersecurity and networking expertise with a strong understanding of manufacturing environments. The successful candidate will serve as a trusted technical advisor and help advance Smurfit Westrock\u2019s operational technology cybersecurity program across a broad and complex global footprint.

How you will impact Smurfit Westrock:

• Design and implement cybersecurity architectures that protect manufacturing systems, industrial networks, and plant operations.

• Develop secure network segmentation, vendor remote access, monitoring, and control strategies that reduce cyber risk while supporting operational reliability.

• Troubleshoot and resolve technical issues involving vendor access, network communications, firewall policies, and cybersecurity controls in manufacturing environments.

• Support engineering, maintenance, operations, site technology teams, and vendors during cybersecurity implementations, remediations, and incident response activities.

• Lead cybersecurity improvement initiatives across manufacturing sites, including secure access, network modernization, monitoring, and risk reduction projects.

• Assess cybersecurity risks affecting manufacturing systems and help prioritize remediation based on business impact, safety, reliability, and exposure.

• Create technical documentation, network diagrams, standards, implementation guidance, and troubleshooting procedures for operational technology environments.

• Partner with cross-functional teams to embed cybersecurity into the lifecycle of manufacturing systems, from design and deployment through ongoing operations.

• Collaborate with security operations teams to improve monitoring, escalation, investigation, and response to cybersecurity events affecting manufacturing environments.

• Contribute to operational technology cybersecurity policies, standards, risk registers, audit readiness activities, and compliance efforts.

• Mentor other cybersecurity engineers and analysts by sharing technical expertise, practical guidance, and operational technology security best practices.

• Serve as a subject matter expert for operational technology cybersecurity across Smurfit Westrock.

What you need to succeed:

Required qualifications:

• Four or more years of cybersecurity experience, including hands-on experience supporting manufacturing, industrial, operational technology, or critical infrastructure environments.

• Strong understanding of industrial control environments, including systems and networks used to support manufacturing operations.

• Strong knowledge of networking fundamentals, including routing, switching, firewalls, network segmentation, and secure remote access.

• Hands-on experience with cybersecurity technologies, such as firewalls, intrusion detection tools, endpoint security tools, security monitoring platforms, or log management systems.

• Experience troubleshooting network connectivity, firewall rules, remote access, and security control issues in operational or production environments.

• Ability to design and implement cybersecurity controls while considering safety, uptime, reliability, and operational impact.

• Bachelor\u2019s degree in Cybersecurity, Computer Science, Engineering, Information Technology, or related field.

• Professional cybersecurity certifications such as CISSP, GICSP, GRID, or equivalent certifications.

• Experience with operational technology cybersecurity monitoring platforms such as Nozomi Networks, Dragos, Claroty, or similar technologies.

• Experience securing vendors and third-party remote access into manufacturing or industrial environments.

• Experience with industrial communication protocols such as Modbus, OPC, Ethernet/IP, or similar plant-floor technologies.

• Familiarity with cybersecurity frameworks, standards, or regulations such as NIST Cybersecurity Framework, NIST guidance for industrial control systems, ISA/IEC 62443, or European cybersecurity requirements.

• Experience supporting cybersecurity audits, assessments, risk registers, remediation plans, or compliance activities.
