OT Security Engineer

OT Security Engineer (Industrial Cyber)

Warrington | Permanent | 3–5 days onsite

Salary: 65K - 75K

Secure systems that actually matter.

This role sits on a major, safety-critical industrial programme where downtime isn't tolerated and cyber security has real-world consequences. You'll be hands-on designing, building, and proving secure OT environments, not just writing policies about them.

What you'll do

• Design and implement secure OT / ICS networks
• Harden PLCs, SCADA, and HMI systems
• Deploy segmentation, firewalls & intrusion detection
• Lead testing, integration & FAT
• Own delivery from design through to commissioning

Why it's worth a look

• You'll own solutions end-to-end, not just advise
• Work on critical infrastructure where your impact is visible
• Close collaboration with automation & project teams

What you'll bring

• Experience securing industrial / OT environments
• Strong networking knowledge (EtherNet/IP, TCP/IP)
• Hands-on with SCADA, PLCs, segmentation & firewalls

Onsite in Warrington (3–5 days/week).
Ideal for someone who prefers real systems over slide decks.
