Reference: 2b0hwor7f8k33dkdyf90

We are seeking a Technical Specialist – OT Security to support the protection, resilience and secure operation of industrial control systems and operational technology environments. In this role, you will provide technical expertise across OT security architecture, risk management, vulnerability reduction and incident preparedness. You will work closely with engineering, operations, infrastructure, compliance and external technology teams to ensure that security measures are practical, proportionate and aligned with operational requirements.

Your responsibilities will include assessing OT networks, control systems and connected devices; identifying security risks and recommending appropriate mitigations; supporting the development and maintenance of OT security standards, procedures and reference architectures; and contributing to secure-by-design principles for new projects and system upgrades. You will help implement monitoring, segmentation, access control, asset management, patching and configuration management capabilities, while taking account of safety, availability and change-control constraints. You will also support security assessments, audits, penetration testing, incident response exercises and investigations involving OT environments, ensuring that findings are documented and addressed effectively.

The successful candidate will have practical experience in OT, ICS, SCADA, industrial networking or a closely related technical security field. A strong understanding of common OT protocols, network architecture, vulnerability management, endpoint protection, identity and access management, and relevant security frameworks such as IEC 62443 or NIST is expected. Experience with risk assessments, security monitoring tools and incident response in operational environments would be advantageous. You should be analytical, collaborative and able to communicate clearly with both technical and non-technical stakeholders. The role requires sound judgement, strong documentation skills and the ability to balance cybersecurity improvements with safety, reliability and business continuity. Relevant professional certifications or qualifications in cybersecurity, networking, engineering or industrial automation are desirable.
