What you will do

• Vet prospective compute providers by assessing cluster architecture, GPU hardware, network fabric, storage, and orchestration.
• Define the technical qualification bar, building acceptance test suites and benchmark methodologies from scratch.
• Perform hands-on validation, including burn-in testing, fabric validation (InfiniBand/RoCE), and NCCL benchmarks.
• Guide provider data-center and platform engineers through technical onboarding and configuration tuning.
• Partner with the compute procurement team to perform technical due diligence on new providers.
• Maintain technical relationships with existing providers to identify architectural or quality drift.

Requirements

• Deep HPC experience designing, building, or operating GPU clusters at scale.
• Strong knowledge of network fabrics, specifically InfiniBand and RoCE.
• Experience with distributed orchestration and HPC software stacks (Slurm, Kubernetes, OpenMPI, Linux).
• Data-center literacy covering power, cooling, cabling, and physical-layer realities.
• Ability to design non-gameable benchmarking tests for large-scale training workloads.
• Capability to write precise, testable technical standards for external engineering teams.

Nice to have

• Experience working within a neocloud, hyperscaler, or colocation provider.
• Deep expertise in NVIDIA data-center GPU platforms (DGX/HGX, NVLink/NVSwitch).
• Experience supporting AI research labs and familiarity with training workload bottlenecks.
• Background in cluster acceptance testing or site bring-up.

Culture & Benefits

• High-growth environment at the center of the AI infrastructure boom.
• High level of ownership as the first HPC Architect for the solutions engineering team.
• Competitive compensation with meaningful equity.
• Comprehensive healthcare, dental, and vision coverage for employees and dependents.
• 401(k) retirement plan and unlimited PTO.
