Emerging Network Architect

NorthMark Compute & Cloud (NMC²) is backed by dedicated leadership and investment, with a clear mission as it operates at the bleeding edge of technology. Its goal is to scale and enhance the high-performance computing (HPC) and cloud infrastructure that supports its clients' research, production, and delivery, enabling breakthroughs that shape the industries of tomorrow. Its engineers build critical infrastructure to eliminate friction in scientific research, simulations, analysis, and decision-making, accelerating discovery and driving faster innovation.

The Position

The Emerging Network Architect role focuses on evaluating, designing, and integrating next-generation networking technologies to support high-performance computing (HPC) platforms. This position works at the intersection of compute, storage, and networking to assess new architectures, benchmark performance, and guide technology selection aligned with scalability, efficiency, and workload requirements. Partnering closely with vendors, internal architects, and customers, the role helps translate evolving network capabilities into practical, production‑ready HPC solutions that can be validated in lab environments and deployed at scale across advanced research and compute systems.

Responsibilities

• Explore opportunities from the industry to utilize future network architectures and technologies that will increase key HPC metrics like Model Flops Utilization, and Performance per Watt
• Develop and maintain strong technical partnerships with leading vendors in networks to incorporate their future roadmaps in our HPC platform and architectures
• Recommend and justify hardware and software solutions aligned with performance, efficiency and scalability objectives
• Work with customers to understand their HPC current and future workloads and requirements and the impact on our models and performance benchmarks
• Evaluate the incoming hardware and software sufficient to verify the systems in our own environment and lab setups
• Aid in bottleneck identification and performance evaluation done within the team for new hardware especially as it pertains to networks, such as latency/bandwidth modelling
• Collaborate with storage and compute architects to stitch together the individual vendor’s pieces to achieve a complete HPC solution
• Contribute technical guidance and support to other internal teams responsible for standing up the chosen architectures at scale
• Constantly evaluate and stay current on the existing and future HPC landscape from proven vendors to start‑ups in exploring the best and brightest ideas and products in this space
• Influencing vendor roadmaps through feedback, joint initiatives and technology evaluations

Requirements

• Bachelor's Degree or equivalent experience
• Deep expertise in network architectures and interconnect topologies with demonstrable experience working on these products for HPC
• Hands‑on experience with high-speed fabric solutions, particularly InfiniBand and NVLink, but also including Ethernet (RoCE) and Omni‑Path, etc.
• Expertise in various forms of packet switching, routing algorithms, flow control, and congestion management and can adapt the right solutions for the highest network performance
• An understanding of how high-speed networking impacts compute and experience with performance modelling and industry standard benchmarks like OSU, MPI, STREAM, etc.
• Previous experience of being hands on in a lab environment through running benchmarks and test jobs on unproven hardware in a testing environment
• Understanding of storage distributed and parallel file systems such as VAST, Lustre and particularly its needs and impact on the network performance of a system
• Proven experience designing HPC clusters and parallel computing environments, with strong proficiency in Linux kernel tuning, system‑level optimisations and performance profiling
• Any experience working with emerging Network trends like CXL, PCIe Gen 6, DPU are not required, but strongly valued
• Demonstrated success working directly with clients to capture technical requirements and deliver tailored, scalable system designs across AI/ML, scientific computing, and CFD workloads
