The Senior Manager, Data Centre Vendor Operations & Governance owns the relationship, governance, and performance oversight of Nscale's colocation and 3rd party data centre providers across EMEA. This role is the single point of accountability for how Nscale partners with its EMEA vendors — ensuring sites are run to standard, changes and incidents are managed smoothly, and vendor performance is tracked and reported consistently across the estate.

This is a pioneering, build role: the successful candidate will establish this function from a single-person operation into a regionally structured team as Nscale's EMEA footprint grows. The role governs the accountability, cadence, and commercial/relationship dimension of vendor management; deep technical facility engineering (M&E design, thermal/cooling engineering, technical audit execution) is provided by Nscale's Reliability Engineering function, with this role commissioning, coordinating, and holding that work to schedule rather than performing it directly.

• Own the strategic relationship with each 3rd party DC vendor across EMEA, acting as primary escalation point for vendor performance, site-level disputes, and contractual issues.

• Own commercial escalation for SLA credits and Master Services Agreement (MSA) compliance.

• Partner with site/GPU operations teams to align vendor change and incident processes with operational scheduling and workload demands.
• Chair a joint governance forum with internal stakeholders to review vendor performance, escalations, and process friction.
• Own the Annual Planned Preventative Maintenance (PPM) Planner — tracking provider-side maintenance schedules and ensuring they're mapped against Nscale's operational cycles well in advance, in partnership with Reliability Engineering and site operations.

• Own vendor-facing coordination of change requests, ensuring technical approval (Reliability Engineering) and scheduling inputs are properly sequenced.
• Act as the vendor-facing point of contact during incidents, ensuring the right internal…
