• Develop strong technical partnerships with leading networking and infrastructure vendors and incorporate future technology roadmaps into platform strategy.
• Recommend and justify hardware and software solutions aligned with performance, scalability, reliability, and efficiency objectives.
• Work with customers and technical stakeholders to understand current and future HPC, AI/ML, scientific computing, and simulation workloads.
• Translate workload requirements into network architecture, topology, bandwidth, latency, and performance requirements.
• Evaluate new networking hardware and software in lab and test environments before broader production deployment.
• Design and execute benchmarks, performance tests, and proof-of-concept environments for emerging technologies.
• Identify network bottlenecks and perform latency, bandwidth, congestion, and performance analysis.
• Partner with compute and storage architects to develop complete end-to-end HPC and accelerated computing architectures.
• Provide technical guidance to infrastructure and engineering teams responsible for deploying selected architectures at scale.
• Continuously evaluate the HPC, AI infrastructure, and networking ecosystem across established vendors, emerging companies, and new technologies.
• Influence vendor product roadmaps through technical feedback, joint evaluations, proof-of-concept testing, and strategic partnerships.
• Support architecture decisions related to high-speed interconnects, cluster fabrics, distributed storage, and GPU-based computing environments.

Qualifications

• Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, or a related technical discipline, or equivalent professional experience.
• Deep expertise in network architectures, high-performance interconnects, and network topologies supporting HPC, AI, or large-scale compute environments.
• Hands-on experience with high-speed networking technologies such as:
  • InfiniBand
  • NVLink / NVSwitch
  • Ethernet / RoCE
  • Omni-Path or similar high-performance fabrics
• Strong understanding of packet switching, routing algorithms, flow control, congestion management, and network optimization.
• Experience evaluating the relationship between networking performance and distributed compute workloads.
• Knowledge of performance benchmarking tools and methodologies such as OSU Micro-Benchmarks, MPI benchmarks, STREAM, or similar tools .
• Hands-on experience working in lab, proof-of-concept, or engineering environments testing new or pre-production hardware.
• Strong understanding of distributed and parallel storage architectures and their network requirements, including technologies such as VAST Data, Lustre, or similar high-performance storage platforms .
• Experience designing HPC clusters, accelerated compute platforms, or parallel computing environments.
• Strong Linux knowledge, including system-level optimization, kernel tuning, performance profiling, and troubleshooting.
• Experience analyzing latency, bandwidth, topology, congestion, and overall system performance across large distributed environments.
• Ability to work directly with technical customers and stakeholders to gather requirements and design scalable infrastructure solutions.

Preferred Experience

Experience with emerging technologies such as the following is highly valued:

• CXL
• PCIe Gen 6 and future PCIe architectures
• DPUs / SmartNICs
• GPU networking and scale-out architectures
• NVIDIA networking technologies
• Advanced Ethernet and ultra-low-latency networking
• AI/ML training infrastructure
• Large-scale GPU clusters
• Scientific computing, simulation, or CFD workloads

Ideal Background

The ideal candidate has worked in environments where network architecture directly impacts compute performance and understands how networking, storage, GPUs, CPUs, and distributed software must work together as a complete system.

Candidates coming from HPC infrastructure, hyperscale computing, AI infrastructure, GPU platforms, semiconductor organizations, networking vendors, research computing, or advanced data center engineering environments may be particularly well aligned.
