Job description

ABB is a global technology leader delivering integrated automation, electrification, and digital solutions for offshore projects.

We are seeking an experienced Network& Cybersecurity Engineer to deliver the design, implementation, and security of the ABB 800xA-based ICSS and PMS network infrastructure, covering the full project lifecycle from engineering and FAT through site installation, testing and commissioning.

This is a technically demanding, project delivery focused role at the intersection of industrial automation, network architecture, and operational technology (OT) cybersecurity.

You will work within a multidisciplinary team of automation, safety, telecom and PMS engineers, playing a critical rolein defining, designing, implementing, and commissioning the network and cybersecurity in

compliant with cybersecurity standards across the full operational lifecycle of ICSS and PMS.

Key Responsibilities

• Engineer, configure and test the 800xAICSS and PMS network infrastructure in line with the approved network architecture and project specifications, including industrial switches, routers and firewalls, network redundancy, VLAN segmentation, IP addressing, firewall/DMZ rule sets and network time synchronization.
• Implement the cybersecurity controls defined in the Cybersecurity Design Specification in accordance with IEC 62443,including Windows server and workstation hardening, Active Directory and role-based access control (RBAC), antimalware, application whitelisting, port/USB lockdown, secure remote access, patch deployment and backup/restore.
• Prepare engineering and testing deliverables, including switch and firewall configuration files, IP/VLAN and port allocation schedules, FAT and SAT test procedures, cybersecurityverification test procedures, test reports and as-built documentation.
