Senior Manager or Director, Low Voltage Design – Fiber & OSP

NScale is a GPU cloud provider engineered for AI, offering high-performance infrastructure for AI start-ups and large enterprises. They are seeking a Senior Manager or Director of Low Voltage Design to lead the design and strategy of fiber and low-voltage infrastructure for data centers focused on GPU-based AI workloads, collaborating with teams across Europe and North America.

Responsibilities:

• Partner with stakeholders in data center architecture, networks, facilities, construction, and operations to align designs with capacity, performance, and reliability requirements
• Contribute to and align with the Nscale European network team on the overall vision, standards, and roadmap for low-voltage and fiber systems across data center, campus, and OSP environments
• Help to establish and maintain global design standards, specifications, and best practices for fiber and copper low-voltage systems
• Partner with the Nscale European network team to implement design for fiber and low-voltage systems supporting GPU-dense AI and HPC deployments, including:
• Structured cabling within white space (MDF/IDF, meet-me rooms, MPO/MTP architectures)
• High-fiber-count backbone and leaf-spine topologies for AI fabrics
• Campus distribution networks and inter-building connectivity
• Outside plant (OSP) fiber routes, duct banks, handholes, manholes, and related civil works
• Oversee development and provide review of detailed design packages, including single-line diagrams, riser diagrams, OSP route plans, cable schedules, splice diagrams, and labeling standards
• Ensure designs meet or exceed applicable codes and standards (for example, TIA/EIA, BICSI, NEC, local telecom and utility requirements)
• Optimize designs for scalability, maintainability, and rapid deployment, with particular focus on:
• High-density fiber management
• Pathway and space planning
• Future capacity and upgrades
• AI / GPU cluster growth and reconfiguration
• Lead the planning and design of campus and OSP fiber infrastructure connecting data centers, network hubs, and carrier meet-points
• Oversee route selection, risk analysis, and redundancy planning (diverse paths, ring topologies, physical separation)
• Define and review designs for duct banks, conduit configurations, vaults, handholes/manholes, aerial versus underground strategies, and building entrances
• Coordinate with long-haul and metro fiber providers and carriers to secure diverse connectivity into sites, including evaluating route proposals, entrance facilities, and demarcation points
• Support contract and commercial discussions with providers by supplying technical requirements, design constraints, and capacity forecasts
• Oversee provider design reviews and ensure their outside plant and entrance facilities align with internal standards for resiliency, separation, and future expansion
• Work with the Nscale European network team to translate GPU / AI workload requirements into low-voltage and fiber design criteria
• Collaborate on fabric design (InfiniBand / high-speed Ethernet, spine/leaf, super-spine, and similar)
• Ensure cabling and pathway designs support high-power, high-density racks, liquid cooling deployments, and rapid reconfiguration
• Incorporate monitoring, testing, and troubleshooting capabilities into designs (OTDR access, test points, structured labeling and documentation)
• Provide technical leadership across the full project lifecycle: concept, schematic, design development, issued-for-construction (IFC), and handover
• Review and approve vendor and contractor submittals, shop drawings, and as-builts for low-voltage and OSP scopes
• Define technical requirements and evaluation criteria for RFPs and vendor selection related to low-voltage and fiber infrastructure
• Act as the primary North America technical point of contact for carriers and dark fiber providers during planning, construction, and turn-up, including coordinating site access, testing, and acceptance
• Support cost estimation and value engineering while protecting performance, reliability, and scalability
• Contribute to and maintain master specifications, design guides, typical details, and standard drawings for:
• Data hall cabling and pathways
• Campus backbone architectures
• OSP fiber routes and components
• Ensure accurate, current documentation (BIM models, GIS/route maps, splice records, labeling databases) for all sites and campuses
• Assist with developing playbooks to standardize deployment and replication of proven designs across regions

Requirements:

• Bachelor's degree in Electrical Engineering, Telecommunications, Computer Engineering, or related field, or equivalent practical experience
• 10+ years of experience in low-voltage and fiber design, with significant focus on data centers, telecom, or large-scale campus networks
• Proven experience leading design for: Structured cabling systems in mission-critical environments. OSP and campus fiber (duct banks, vaults, aerial and underground, building entry)
• Strong understanding of: TIA/EIA, BICSI, and relevant telecom and electrical codes. High-density fiber architectures (MPO/MTP, cassette-based systems, spine/leaf designs). Redundancy and resiliency concepts (A/B paths, dual home, ring and mesh topologies)
• Demonstrated leadership experience managing teams and/or large design programs
• Ability to read, create, and review detailed design documentation (AutoCAD, Revit/BIM, GIS or equivalent tools)
• Excellent communication skills, with ability to convey complex technical concepts to both technical and non-technical stakeholders
• Experience with GPU-dense AI, HPC, or large-scale cloud data center designs
• Experience collaborating on high-speed fabric design (InfiniBand, 100G/400G/800G Ethernet, or similar)
• Professional certifications such as RCDD (BICSI) or equivalent telecom / low-voltage credentials
• Experience working with carriers, utilities, and local authorities for OSP design, permitting, and construction
• Background in global or multi-site programs, with repeatable design standards and templates
