Who are we looking for?

This role requires someone who specialises in building and maintaining OT incident response capabilities across both SOC services and consulting engagements, working to enhance clients’ OT security programs whilst developing internal expertise.

• Self‑manage the development and maturity of our OT incident response service offerings, including technical documentation, playbooks, and response procedures tailored for ICS/OT environments.

• Build and implement OT incident response processes for SOC analysts, including triage procedures, investigation methods, and escalation paths for industrial control systems, occasionally serving as the escalation point.

• Lead technical investigations into OT security incidents, providing expert guidance on containment and remediation while considering operational impact and safety.

• Develop a team of OT incident responders, offering technical mentorship and ensuring consistent delivery across multiple client environments.

• Support and guide customers in developing OT incident detection and response capabilities.

• Design and maintain OT‑specific incident response plans and playbooks aligned with industry standards and best practices.

• Act as a thought leader in OT security through blogs, whitepapers, webinars, and speaking engagements.

• Create and deliver OT cyber incident exercises and tabletop scenarios for technical and executive stakeholders using realistic threat intelligence.

• Serve as senior incident coordinator during active OT incidents, managing communications and balancing security with operational continuity.

You will need to have experience in:

• Extensive experience with industrial control systems, SCADA, and OT networks, including understanding of common protocols (Modbus, DNP3, OPC, etc.).

• Experience with common OT security tools such as Forescout, Nozomi and Claorty.

• Relevant certifications such as GRID, GICSP, GREM, CSSA, or equivalent OT security qualifications.

• Experience in MSSP and/or OT security consulting roles, with demonstrated ability to build and develop service offerings.

• Strong background in incident response and crisis management within regulated CNI environments.

• Knowledge of frameworks such as IEC 62443, NIST CSF, NCSC CAF, NIS regulations, and the Purdue Model.

• Experience in leading technical teams and developing junior staff members.

• Demonstrated ability to communicate complex technical concepts to various audiences through presentations, written content, and training materials.

• Background in developing and implementing SOC processes and procedures for OT security monitoring and incident response.

This position requires travel to client locations, up to 50% of working time, with expenses. The role may require on‑call responsibilities as part of the OT incident response rotation.
