We provide cost-effective, high-performance infrastructure for AI start-ups and large enterprise customers. Nscale enables AI-focused companies to achieve superior results by reducing the complexity of AI development. Our GPU cloud bolsters technical capabilities and directly supports strategic business outcomes, including cost management, rapid innovation, and environmental responsibility.\nWe 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 an Nscaler, you'll build trust through openness and transparency, where everyone is inspired to do their best work. If you join our team, you'll be contributing to building the technology that powers the future.\nAbout the Role\nWe're looking for a Senior Network Engineer to build and bring up the networks 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.\nThis is a hands-on engineering role. You'll take network designs into production: configuring and validating cluster fabrics, front-end networks, and WAN edge, troubleshooting issues during bring-up, and making sure every build is ready for customers. The role involves regular travel to our sites.\nWhat You'll be Doing\nDeploy, configure, and validate high-performance Ethernet and InfiniBand fabrics for large GPU clusters.\nBring up front-end, storage, and management networks and WAN edge connectivity for new sites and expansions.\nRun network acceptance testing and performance validation ahead of customer handover.\nTroubleshoot and resolve issues across routing, switching, optics, and cabling during build and early life.\nWork with Network Architecture to refine reference designs, BOMs, and build standards based on what you learn in the field.\nBuild and improve automation for provisioning, configuration, and validation.\nPartner with Technical Program Managers, Data Centre Operations, and vendors to keep builds on schedule.\nWrite clear runbooks and documentation so builds are repeatable across sites.\nAbout You\n5+ years of network engineering experience in large-scale data centre, cloud, or HPC environments.\nExperience at a hyperscaler or major network vendor (e.g. Microsoft, AWS, Oracle/OCI, Cisco) or a comparable large-scale network.\nStrong hands-on knowledge of routing and switching: BGP, OSPF, EVPN/VXLAN, ECMP, and L2/L3 data centre design.\nExperience deploying and operating cluster networks, ideally including InfiniBand or RoCE fabrics.\nPractical experience with network automation (Python, Ansible, or similar).\nCalm, methodical troubleshooter who can work under deadline pressure on live builds.\nWillingness to travel across Europe to sites as needed.\nNice to Have\nExperience building networks for GPU clusters or AI training environments.\nFamiliarity with HPC topologies (Fat Tree, Rail) and 400G/800G optics.\nExperience with SONiC, Cumulus, or other open networking platforms.\nWAN, peering, or DWDM experience.\nIndustry certifications such as CCNP/CCIE, JNCIP/JNCIE, or NVIDIA networking certifications.\nWhy this role matters\nThe network is what turns thousands of GPUs into a single system. Your work decides how fast new clusters reach customers and how well they perform once they do.\nEqual Opportunities Statement\nAt Nscale, we are committed to fostering an inclusive, diverse, and equitable workplace. We believe that a variety of perspectives enriches our work environment, and we encourage applications from candidates of all backgrounds, experiences, and abilities. We strongly encourage applications from people of colour, the LGBTQ+ community, people with disabilities, neurodivergent people, parents, carers, and people from lower socio-economic backgrounds.\nIf there's anything we can do to accommodate your specific situation, please let us know.\nThe responsibilities outlined in this job description are not exhaustive and are intended to provide a general overview of the position.
