We are seeking a Specialist HPC Infrastructure Solutions Architect to design, build, and optimize next-generation high-performance computing (HPC) platforms for AI, simulation, and large-scale data processing workloads. The ideal candidate combines deep knowledge of cloud-native architecture, Kubernetes orchestration, networking, and HPC system design with hands-on experience implementing NVIDIA GPU-based compute environments and MLOps toolchains. This role sits at the intersection of infrastructure engineering, accelerated computing, and AI systems design, shaping the foundation for high-throughput, low-latency distributed workloads in cloud environment.

You’re welcome to work remotely from the United States or Canada.

Your responsibilities will include:

• Architect and implement scalable HPC clusters optimized for AI, simulation, and distributed training, leveraging container orchestration frameworks and schedulers (e.g., Kubernetes, Slurm).
• Design and integrate GPU-accelerated compute infrastructures featuring NVIDIA Hopper, Blackwell architectures, NVLink/NVSwitch, and InfiniBand/RoCE Interconnects.
• Deploy, and manage GPU Operator and Network Operator stacks for automated lifecycle management of GPU and high-speed networking components.
• Design and validate cloud HPC environments, focusing on low-latency, high-bandwidth networking, multi-GPU scaling, and efficient workload scheduling.
• Lead reference architectures for AI/ML model training, data pipelines, and MLOps integrations using modern observability and CI/CD tooling.
• Collaborate with hardware vendors (e.g., NVIDIA) and cloud providers to evaluate and optimize emerging HPC and GPU technologies.
• Benchmark system performance, identify bottlenecks, and tune resource utilization across compute, network, and storage tiers.
• Provide expert-level technical guidance to customers, internal teams, and partners on HPC architecture patterns, operational excellence reviews and customer engagements

We expect you to have:

• Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field (Ph.D. a plus)
• 3+ years of hands-on experience architecting HPC or large-scale GPU clusters.
• Expertise in Linux systems, Kubernetes, container runtimes (containers, CRI-O, Docker), and related CI/CD practices.
• Strong understanding of HPC networking protocols and RDMA stacks (InfiniBand, NVLink/NVSwitch)
• Deep understanding of storage and I/O optimization for large datasets (Ceph, Lustre, NFS, GPUDirect Storage)
• Familiarity with Terraform, Ansible, Helm, and GitOps workflows.
• Strong scripting skills in Python or Bash for automation and tool integration.
• Excellent communication and documentation skills; ability to lead design
• reviews and customer engagements

It will be an added bonus if you have:

• Proficient with NVIDIA GPU ecosystem: GPU Operator, MIG, DCGM, NCCL, Nsight, and CUDA stack management.
• Experience designing or managing AI/ML pipelines via MLflow, Kubeflow, NeMo, or similar frameworks.
• Experience with cloud-native HPC offerings (Slurm, LFS, PBS, etc.).
• Background in designing multi-tenant GPU infrastructures or AI training farms.
• Exposure to distributed ML frameworks (PyTorch DDP, DeepSpeed, Megatron).
• Knowledge of observability for HPC (Prometheus, DCGM Exporter, Grafana, NVIDIA NGC monitoring tools)
• Contribution to open-source HPC/CUDA/Kubernetes projects is a strong plus

Key Employee Benefits:

• Health Insurance: 100% company-paid medical, dental, and vision coverage for employees and families.
• 401(k) Plan: Up to 4% company match with immediate vesting.
• Parental Leave: 20 weeks paid for primary caregivers, 12 weeks for secondary caregivers.
• Remote Work Reimbursement: Up to $85/month for mobile and internet.
• Disability & Life Insurance: Company-paid short-term, long-term, and life insurance coverage.

Compensation

We offer competitive salaries, ranging from 225k - 315k OTE (On-Target Earnings) and equity based on your experience, skills, and location.
