OT Cyber Solution Architect – (Reading 1-2 days a week max.) – 6 months (£635 – 682)

Must have OT Cyber experience!

End to End Architecture Leadership:

• Define and deliver Zero Trust OT architecture, including:
• NAC (FortiNAC)
• NDR (Claroty + Fortigate + Fortiguard +SOC integration)
• EDR (SentinelOne and Microsoft Defender)

Scope: The architect will lead design and delivery across the entire scope of this project containing 3 workstreams:

1. Network Access Control (NAC)

• Implement NAC (802.1X) across L2 Switches in 64 OT sites
• Deliver: Device authentication & posture checking
• Dynamic access control and segmentation
• Safe deployment in OT constrained environments

2. Endpoint Detection & Response (EDR)

• Deploy advanced endpoint protection capability (EDR) to: ~2000 OT compute endpoints
• Using: SentinelOne (currently in POC) for air-gapped endpoints
• MDE for Internet exposed endpoints
• Ensure: Behaviour based threat detection
• Safe deployment in OT constrained environments

3. Network Detection & Response (NDR) + OT Visibility

• Deploy across: Layer 3/Boundary NW of 111 sites
• Using the following stack: FortiNAC + FortiGate + FortiGuard + Claroty

You will be a hands on OT Cyber Solution Architect responsible for owning Design and Implementation of Zero Trust architecture, ensuring successful rollout across a complex, safety critical OT environment.

The role will lead OT teams and SMEs, providing clear Design and technical direction, fostering collaboration, and ensuring solutions are practical, deployable, and aligned to operational constraints.
