• Communicating operational risks, service performance and remediation plans to senior stakeholders.

We’re looking for someone with:

• Strong experience leading technical support or service operations within an OT environment.
• Hands-on knowledge of DMS, SCADA, data historians, telemetry or communications systems.
• Proven experience managing incidents and restoring services in high-availability environments.
• A strong understanding of OT patching, vulnerability remediation and controlled maintenance.
• Experience leading, coaching and developing technical teams.
• Excellent stakeholder, supplier and service-management skills.
