About the Role
We're looking for a Technical Program Manager to drive the delivery of the network builds behind Nscale's GPU clusters across Europe. You'll join our Deployment organisation, a build org that owns every step from hardware arrival on site through to customer acceptance.
This is a delivery-ownership role, not a pure coordination one. You'll run the schedule, risk, and dependency management for network bring-up across multiple concurrent sites, translating network designs and vendor commitments into a build plan the whole team can execute against — and you'll be close enough to the technical detail to know when a "green" status isn't actually green. The role involves regular travel to our sites.
What You'll be Doing
- Own the end-to-end program plan for network deployment across GPU cluster builds — from hardware delivery and cabling through fabric bring-up, acceptance testing, and customer handover.
- Drive cross-functional coordination between Network Engineering, Network Architecture, Data Centre Operations, vendors, and customers to keep builds on schedule.
- Identify, track, and resolve schedule risks and blockers before they hit the critical path — long-lead optics and hardware, vendor delays, site readiness, staffing.
- Build and maintain reporting on program status, milestones, and risk for leadership and customer-facing stakeholders.
- Manage vendor and partner delivery commitments for network hardware, optics, and installation services, holding them accountable to schedule and quality.
- Run program governance: regular cadence calls, RAID logs, change control, and post-build retrospectives to improve future builds.
- Partner with Network Architecture and Engineering to turn reference designs and BOMs into site-specific, sequenced build plans.
- Coordinate acceptance testing and validation milestones ahead of customer handover, ensuring documentation and sign-off requirements are met on time.
About You
- 5+ years of technical program or project management experience in large-scale data centre, cloud, or network infrastructure environments.
- Experience at a hyperscaler, cloud provider, or major network vendor, or delivering comparable large-scale infrastructure programs.
- Strong working knowledge of data centre networking concepts (routing/switching, fabric architectures, WAN edge) sufficient to assess technical risk and challenge status reporting — you don't need to configure the fabric, but you need to understand what "done" looks like.
- Track record of managing multiple concurrent, fast-moving builds with hard customer deadlines.
- Skilled at vendor and stakeholder management, including holding partners accountable to committed schedules.
- Strong program reporting and communication skills — able to translate technical status into clear, decision-ready updates for leadership and customers.
- Calm under pressure, comfortable making trade-off calls on live builds with incomplete information.
- Willingness to travel across Europe to sites as needed.
Nice to Have
- Experience program-managing GPU cluster, HPC, or AI training infrastructure builds.
- Familiarity with network fabric technologies relevant to GPU clusters (Ethernet/InfiniBand, EVPN/VXLAN, RoCE).
- Experience with program and risk tooling (e.g. Jira, Smartsheet, Monday, RAID/MOP frameworks).
- PMP, PRINCE2, or equivalent program/project management certification.
- Experience standing up or improving build-program processes in a scaling organisation.
Why this role matters
Every day a network build slips is a day a customer's GPUs sit idle. Your work decides whether our builds land on schedule, on spec, and ready for the customers waiting on them.
