Network Deployment Engineer EMEA; London

Nscale is taking on the hyperscalers by building a vertically integrated cloud built for AI. We own the data centres, software, and applications that power today's AI stack using sustainable technology solutions. We thrive on a culture of relentless innovation, ownership, and accountability, where every team member takes pride in their work and drives it with excellence and urgency. As a Nscaler, you’ll build trust through openness and transparency, where everyone is inspired to do their best work. Collaboration is key, and we work together swiftly and respectfully, embracing adaptability and resilience in all we do.

About the Role

As a Network Deployment Engineer, you will be on the ground in datacentres, installing, commissioning, and validating the networks that power Nscale’s GPU clusters. You’ll work directly with network gear, cabling, and racking, ensuring new deployments are delivered to specification and fully operational. This role is efficient, requiring hands-on work with switches, routers, fibre/ethernet cabling, and test equipment. You’ll bring up links, verify connectivity, and hand off to network engineering teams once platforms are live. This role requires travel to DC locations 50%–70% of the time.

What you’ll be doing

• Install, rack, cable, and patch switches, routers, and optics for new network deployments.
• Perform on-site validation and acceptance testing of deployed hardware (link tests, optics checks, interface bring-up).
• Execute deployment runbooks for new datacentre builds and expansions.
• Label, document, and maintain structured cabling standards across sites.
• Work with network engineers to configure devices using provided templates or scripts.
• Assist with fabric validation (Ethernet, InfiniBand, RDMA) for GPU cluster connectivity.
• Maintain accurate records of hardware installs, cabling maps, and deployment checklists.
• Coordinate with vendors and logistics teams for hardware deliveries and replacements.
• Support capacity expansion projects and scaling activities across global datacentre sites.

About You

• 2–4 years of experience in datacentre network deployment, field engineering, or infrastructure installation.
• Comfortable with racking and stacking network gear, structured cabling, and on-site troubleshooting.
• Familiar with network hardware (Cisco, Arista, Juniper, Mellanox/NVIDIA, etc.).
• Understanding of fibre/ethernet cabling types, optics, and patching standards.
• Basic knowledge of IP networking (VLANs, trunks, link aggregation).
• Experience following deployment runbooks and MOPs (Methods of Procedure).
• Strong focus on safety, organisation, and documentation.
• Able to work independently in datacentres and travel internationally when required.

Nice to Have

• Prior experience with HPC or GPU-dense datacentre deployments.
• Exposure to automation (Python, Ansible) for device staging/config.
• Knowledge of datacentre standards (TIA/EIA cabling, hot/cold aisle, structured labelling).
