Your role and responsibilities

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 role in defining, designing, implementing, and commissioning the network and cyber security in compliant with cybersecurity standards across the full operational lifecycle of ICSS and PMS.

The work model for this role is onsite #onsite

Key Responsibilities

• Engineer, configure and test the 800xA ICSS 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, cybersecurity verification test procedures, test reports and as-built documentation.
• Participate in FAT and SAT activities, including network validation, cybersecurity verification testing, and troubleshooting of network and security-related issues.

Required Qualifications & Experience

• Bachelor’s degree in Electrical, Electronics, Instrumentation, Telecommunication or Computer Engineering.
• Min. 5 years of hands-on experience in industrial network and/or OT cybersecurity engineering, testing and commissioning on DCS/ICSS/PMS platforms; experience on offshore, marine or FPSO projects is strongly preferred.
• Hands-on experience with industrial network design (Belden / Cisco switches, routers, firewalls) in an ICSS/PMS environment.
• Experience with ABB System 800xA networks or comparable DCS platforms (Honeywell, Emerson, Yokogawa) is an advantage.
• Working knowledge of industrial protocols (Modbus TCP/RTU, OPC/OPC UA, PROFIBUS, PROFINET, EtherNet/IP and IEC 61850).

What’s in it for you

• Work on complex offshore automation and cybersecurity projects using ABB’s industry-leading technologies.
• Develop your expertise in OT cybersecurity, industrial networking, and control systems.
• Collaborate with a global team of automation, power management, and cybersecurity specialists.
