SOAR/SIEM Security Engineer - Critical National Infrastructure (OT)
18-Month FTC | SC Cleared
A leading cyber security firm is looking for a SOAR/SIEM Security Engineer to join a critical national infrastructure (CNI) client on an 18-month fixed-term contract, supporting the protection of operational technology (OT) environments that underpin essential national services.
This is a high-visibility role within a security operations function tasked with detecting, responding to, and automating defence against threats across converged IT/OT infrastructure. You'll be working on live, high-stakes environments.
What you'll be doing
Designing, building, and maintaining SOAR playbooks to automate detection and response workflows
Developing and tuning Splunk use cases, dashboards, and correlation searches across IT and OT data sources
Supporting incident detection and response within CNI/OT environments, working closely with engineering and safety teams
Contributing to the maturity of security monitoring across converged industrial and enterprise networks
Working within a team that understands the unique constraints of OT - availability, safety, and legacy systems - versus traditional IT security
What you'll need
Active SC clearance
Proven experience working within CNI or OT environments
Strong hands-on experience with SOAR platforms and Splunk
A solid grasp of the differences between securing OT and IT - this isn't a generic SOC role
Comfortable operating in a live, high-consequence environment where good judgement matters as much as technical skill
The contract
18-month FTC
Strong potential for extension or conversion to a permanent role further down the line (not guaranteed, but a realistic prospect based on programme trajectory)
