Your new role
We're looking for a hands‑on OT Security Engineer to play a key role in strengthening and evolving operational technology security across complex, business‑critical environments.
This contract focuses on designing, implementing and maturing OT security tooling, initially leading the deployment of EDR, ITDR, NDR and ICS monitoring solutions into OT networks, alongside the rollout of hardened security baselines. You'll work closely with SOC, security architecture and incident response teams to integrate solutions into a centralised SIEM/SOC capability and fine-tune detection and response.
This is a highly technical, electrofocusing role offering real ownership, autonomy and impact.
Key Responsibilities
Lead the implementation, configuration and optimisation of OT security technologies (EDR, ITDR, NDR, ICS monitoring)
Integrate OT security tooling with a central SOC/SIEM environment (including alerting, detection and response tuning)
Take a threat led approach to security configuration, aligned to MITRE ATT&CK, Cyber Kill Chain and relevant threat intelligence
Roll out endpoint and ICS monitoring agents across OT environments, including remote and critical locations, working closely with operational teams to minimise disruption.
Establish operating models, alerting processes and clear RACI ownership for OT security platforms
Support incident response activities and continuous improvement of detection capability
Work with vendors, security teams and OT stakeholders to maximise value and platform performance
Produce clear management information and security insights from deployed technologies
What you'll need to succeed
Strong background in security engineering or security operations, ideally within OT or regulated environments
Hands on experience with areas such as EDR, NDR, XDR, SIEM, endpoint security, network security or ICS monitoring
Good understanding of threat models, adversary tactics and defensive frameworks
Experience integrating security tooling into SOC environments (e.g. SIEM/XDR platforms)
Comfortable working independently while engaging confidently with technical and non‑technical stakeholders
Exposure to OT environments and standards (e.g. NIS, NIS‑CAF) is highly desirable
