Implement and manage comprehensive security measures for OT networks, applying the principle of least privilege (PoLP) and continuously improving defenses.
Conduct security and regulatory audits of OT infrastructure, including NIS2 compliance assessments, and assist in remediation of identified gaps.
Ensure OT security practices align with industry standards (e.g., NIST, IEC 62443) and regulatory frameworks, including the EU NIS2 Directive.
Develop, maintain, and execute OT-specific incident response plans, including procedures for timely reporting to national authorities under NIS2.
Investigate security incidents, ensure effective resolution, and document lessons learned to strengthen incident response capabilities.
Identify, assess, prioritize, and coordinate timely remediation of vulnerabilities in OT environments, aligned with GICS (Global Information Cyber Security department) policy expectations.
Manage and continuously review firewall rules, network segmentation, access controls, and user permissions based on job roles and operational needs.
Deploy, configure, and operate security monitoring tools to detect and respond to anomalous activities within OT networks.
Develop, update, and enforce OT-specific security policies, standards, and operational procedures.
Conduct risk assessments for OT systems and collaborate with GICS to integrate risk findings into hardening and mitigation strategies.
Assess and manage cybersecurity risks associated with critical third-party suppliers and service providers.
Support OT leadership in demonstrating cybersecurity governance, accountability, and compliance with regulatory obligations.
Contribute to cybersecurity awareness and training initiatives tailored to OT personnel, emphasizing NIS2 requirements and best practices.
Maintain accurate and up-to-date documentation of OT system configurations, security controls, incident response plans, and business continuity measures.
Collaborate with Enterprise Architecture, GICS, and Operations teams to ensure holistic security integration for new and existing OT systems.
Participate in the design, review, and hardening of security architectures for OT environments, following industry best practices.
Stay informed of emerging threats, vulnerabilities, and trends in OT cybersecurity, applying knowledge to enhance the organization's security posture.
Collaborate with Business Continuity and Disaster Recovery teams to ensure resilience and continuity plans meet NIS2 expectations for essential services.
Engage in occasional travel and on-call responsibilities as needed to support OT operations and incident response.
Required Skills:
Ability to speak English fluently in a professional work environment.
Proven experience in OT cybersecurity engineering, ideally in industrial, manufacturing, or critical infrastructure environments.
Solid understanding of OT security frameworks and standards (e.g., NIST CSF, IEC 62443).
Solid understanding of OT network communication protocols (e.g., TCP/IP, UDP, DNP3, Modbus, IEC 61850, OPC, OPC UA, and PROFINET).
Familiarity with EU cybersecurity regulations, particularly the NIS2 Directive, and experience supporting compliance initiatives.
Experience with incident response processes, forensic investigations, and regulatory reporting of cybersecurity incidents.
Practical knowledge of risk assessment methodologies and supply chain cybersecurity risk management.
Experience of working as a technology generalist with a high-level understanding of end-to-end solutions including infrastructure, applications, databases, networking and security with the ability to advise on security best practices for new solution implementations.
Strong skills in firewall management, network segmentation, access control, and OT system hardening.
Ability to develop security documentation, procedures, and governance reports tailored for operational environments.
Strong collaboration skills, able to work effectively with multidisciplinary teams including GICS, Enterprise Architecture, Operations, and Legal/Compliance departments.
Willingness to travel occasionally and participate in on-call rotations to support 24/7 OT environments.
Education:
Minimum of Bachelor's degree in a technical area (computer science, engineering, cyber security).
Relevant certifications are a plus (e.g., GICSP, GRID, ISA/IEC 62443 certifications, CISSP, CISM, or comparable).
Experience:
3+ years of experience supporting enterprise-level technology operations and services.
3+ years of experience in a manufacturing environment.
3+ years of experience in cybersecurity engineering and industrial control systems (ICS)/OT security.
