Job Summary
We are seeking a seasoned IT OT Cybersecurity Specialist bridging enterprise IT security and industrial control systems. You will design and enforce defences across our converged IT and OT environments shielding critical infrastructure manufacturing lines and process-control assets from increasingly sophisticated threats. Success in this role means neutralizing risk without ever compromising the availability resilience and safety that industrial operations depend on
Responsibilities
Design implement and maintain security controls across IT and OT ICS environments including SCADA DCS PLCs HMIs and industrial networks.
Conduct risk assessments threat modelling and vulnerability assessments for OT assets accounting for safety and availability constraints unique to industrial systems.
Implement and manage network segmentation strategies (e.g. Purdue Model zones and conduits) between IT and OT networks.
Lead incident detection response and recovery for OT security events coordinating with plant operations and engineering teams.
Deploy and manage security monitoring tools such as SIEM OT specific IDS IPS (e.g. Nozomi Claroty Dragos) and anomaly detection platforms.
Develop and enforce security policies standards and procedures aligned to frameworks like IEC 62443 NIST CSF NIST 800 82 and ISO 27001.
Perform security architecture reviews for new OT projects industrial equipment procurement and remote access solutions.
Manage patch and vulnerability lifecycle for OT assets balancing security with uptime and vendor constraints.
Support regulatory and compliance requirements relevant to critical infrastructure (e.g. NERC CIP sector specific mandates).
Collaborate with engineering operations and IT teams to embed security into the OT lifecycle and drive security awareness among plant personnel.
Site specific OT AD RODC per site isolated child domain mirroring Impact AD OT Forest
New connection to OT infrastructure services i.e. user identification authentications time synchronisation central data logging Backup DR
GxP validation support Template updates compliance documentation and IQ OQ per site
Mapped all MES Serialization and Automation systems assessed impact on Enterprise Infrastructure
OT asset migration from shared IT to dedicated OT cutovers aligned to planned outages
