Overview

You will join Bilfinger UK’s Automation team on a project-based contract to design, build, and test OT networks and cyber security controls for an Industrial Control System environment. You’ll own the cybersecurity delivery for the project, ensuring availability, safety, and compliance while coordinating with multi-disciplinary teams. The role blends engineering delivery with project management, risk and commercial support. This is a hands-on opportunity to shape secure OT solutions at scale.

Responsibilities

• Lead the technical delivery of OT networks and cyber security controls for the project
• Design, implement and test secure ICS networks and systems
• Produce and update technical documentation (design specs, test procedures, O&M docs)
• Deploy and validate networks and security controls for PLC/SCADA environments
• Conduct system integration and FAT
• Support lifecycle activities (vulnerability management, patching, passwords)
• Collaborate with Project Engineering Management, Lead Automation Engineers and OT Cyber Security Manager to plan and execute OT security across projects
• Support commercial teams with technical aspects of sub-contracts
• Provide health and safety leadership by example

Key requirements

• Proven experience in design, implementation and testing of OT/ICS networks and cyber security in industrial settings
• Full project lifecycle experience from specification through deployment and testing
• Experience in hardening PLC, HMI, and SCADA systems to industry standards
• Secure deployment and hardening of network infrastructure (segmentation, boundary protection, switches, firewalls, NIDS)
• Hands-on network design with Hirschmann managed switches/firewalls; time synchronization (NTP)
• Experience with automation OEMs (Rockwell, Bentley Nevada, Det-Tronics, Opto 22)
• Understanding of OSI/TCP/IP and industrial protocols (EtherNet/IP/CIP Security beneficial)
• Strong troubleshooting, documentation and stakeholder communication
• QMS experience with traceability through project lifecycle
• Security certifications in OT (e.g., ISA/IEC 62443, GIAC GISCP, CCNA/CCNP) (any of these as relevant)

• Pro-active mindset
• Strong collaboration and coordination with cross-functional teams
• Effective stakeholder communication
• OT/ICS network design and security
