The role

A venture-backed investment firm is standing up a substantial GPU compute capability, having just confirmed a large-scale order of next-generation B300 GPUs. This is a rare opportunity to architect large-scale AI infrastructure from the ground up, owning cluster specification and costing for a major hardware deployment rather than inheriting someone else's design decisions.

Own the technical architecture behind a landmark GPU deployment, shaping cluster topology, networking, and power/cooling decisions that will underpin the firm's compute strategy for years to come.

Join a fast-moving investment platform with capital already committed and hardware secured, giving this role immediate, tangible scope rather than a speculative roadmap.

Work closely with senior stakeholders in a lean, high-trust environment where your technical judgement directly shapes commercial decisions worth millions.

Responsibilities

  • Specify and design GPU cluster architecture for a large-scale B300 deployment, covering compute, networking, storage and interconnect
  • Produce detailed costing models for cluster builds, including hardware, data centre, power and ongoing operational expenditure
  • Evaluate and recommend data centre/colocation partners capable of supporting high-density GPU racks
  • Define networking topology (InfiniBand/Ethernet fabric) to optimise for distributed training and inference workloads
  • Liaise with hardware vendors, OEMs and data centre providers to validate specifications and negotiate technical terms
  • Produce technical documentation and board-level summaries translating complex infrastructure decisions into commercial terms
  • Advise on power, cooling, and rack density requirements specific to next-generation GPU deployments

Skills/Must have

  • Experience: 7+ years in infrastructure/solutions architecture, with direct experience specifying GPU or HPC clusters at scale
  • Core Tech/Domain: Deep hands-on knowledge of GPU hardware (NVIDIA H100/H200/B200/B300 class systems), server/rack design, and data centre infrastructure
  • Methodology/Protocols: Strong grasp of InfiniBand/RDMA networking, NVLink/NVSwitch topologies, and cluster interconnect design for distributed compute workloads
  • Soft Skills: Confident operating at boardroom level, able to translate deep technical detail into commercial costing narratives; comfortable owning ambiguous, high-stakes decisions with minimal oversight

Nice to haves

  • Experience with liquid cooling/high-density rack deployments
  • Prior work with hyperscalers, neo-clouds, or GPU-as-a-service providers
  • Familiarity with NVIDIA reference architectures (e.g. DGX SuperPOD)
  • Vendor relationships with NVIDIA, Dell, Supermicro, or major colocation providers

Salary

  • £110,000-£150,000 base (DOE) + performance bonus
