Volta is building AI infrastructure at scale, starting with a 133MW AI factory in Norway. As OT Systems Subject Matter Expert, you will be the technical authority for all operational technology systems across Volta's AI factories—Building Management Systems (BMS), Electrical Power Monitoring Systems (EPMS), SCADA, PLC-based controls, and Data Centre Infrastructure Management (DCIM) platforms. You report to the Senior Director, Operations Engineering.
You will set Volta's OT standards and reference architecture, define OT cybersecurity requirements in partnership with IT, and support the design, construction, and commissioning of new sites. You'll work across Design, IT, Construction, Asset and Inventory, and Site Operations to ensure OT systems are built and operated to a single standard across all facilities.
Key responsibilities include: acting as technical authority for OT system standards and design guidelines; reviewing and approving OT designs, control philosophies, and sequences of operation for new builds and retrofits; leading OT input into commissioning (Levels 1–5 and IST) with integrated testing and sign-off; implementing the OT cybersecurity framework covering network segmentation, access control, patching, and vulnerability management; maintaining accurate OT asset inventory and network documentation across all sites; providing escalation support for OT incidents and leading root cause analysis; governing OT change management to ensure zero customer-impacting incidents; managing OT vendors and system integrators; aligning OT/IT integration and data flows; ensuring consistency across sites through common standards and naming conventions; protecting resilience through redundancy reviews and disaster recovery planning; ensuring compliance with operating principles, safety rules, and customer SLAs; driving continuous improvement through analytics and PUE optimization; and developing training materials to raise OT competence across Operations.
In your first year, success means: an approved Volta OT standard and reference architecture ready for every new project; 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; OT readiness built into commissioning with clear acceptance criteria; and key OT vendors working to clear technical scopes and KPIs with trained site teams.
This role requires a hands-on technical expert who combines deep OT and controls knowledge with a strong security mindset and 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 teams around you.
