About The Role

Volta is building AI factories across Europe and North America, starting with a 133MW AI factory in Norway on NVIDIA Vera Rubin systems. Every one of them depends on the operational technology that monitors and controls its power and cooling. The OT Systems Subject Matter Expert is Volta's technical authority for those systems: Building Management Systems (BMS), Electrical Power Monitoring Systems (EPMS), SCADA, PLC-based controls and Data Centre Infrastructure Management (DCIM) platforms. The role reports to the Senior Director, Operations Engineering.

You will set Volta's OT standards and reference architecture, define OT cybersecurity requirements with the IT team, support the design, construction and commissioning of new sites, and give Operations full expert support so our services stay safe, secure and available. You will work closely with Design, IT, Construction, Asset and Inventory, and Site Operations so the OT across our AI factories is built and run to one standard.

In your first year, success means an approved Volta OT standard and reference architecture ready for every new project; a complete, validated OT asset inventory and network documentation for every site; an OT cybersecurity baseline assessment across the portfolio; a formal OT change and patch management process, with zero customer-impacting incidents caused by OT changes; OT readiness built into commissioning and handover with clear acceptance criteria; and key OT vendors working to clear technical scopes and KPIs, with site teams trained.

This is a role for a hands-on technical expert who combines deep OT and controls knowledge with a strong security mindset and a full understanding of the data centre facility stack. You will move comfortably between design reviews, live-site troubleshooting and senior stakeholder discussions, stay calm under pressure, own problems through to resolution and enjoy raising the capability of the teams around you.

What You Will Be Doing

• Act as the technical authority for OT across Volta's AI factories, owning OT system standards, reference architectures and design guidelines in close partnership with the Design team
• Review and approve OT designs, control philosophies, points lists and sequences of operation for new builds, expansions and retrofits
• Lead OT input into commissioning (Level 1–5 and IST), including integrated testing of BMS, EPMS and control systems, and sign off OT readiness for handover to Operations
• Implement the OT cybersecurity framework with the IT team, covering network segmentation, access control, patching, backup and vulnerability management
• Maintain an accurate OT asset inventory, network architecture documentation and configurationmbaselines across all sites, with the Asset and Inventory team
• Provide escalation support for OT incidents, lead root cause analysis and drive corrective and preventive actions
• Govern OT change management so every change to a live system is risk-assessed, tested and carried out with zero impact on customer SLAs
• Manage OT vendors, system integrators and OEMs at a technical level, including scope definition, performance reviews and lifecycle and obsolescence planning
• Work with IT, Design, Construction and Site Operations to align OT/IT integration, data flows and alarm management
• Keep OT systems consistent across every site, with common standards, naming conventions, templates and graphics
• Protect OT resilience and business continuity through redundancy reviews, drills and documented disaster r
