HPC Network Architect

THE COMPANY 

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 Architecture team's mission is to build a sound, coherent architecture for the HPC platform. The team takes in product requirements and operational constraints, incorporates validated new technologies and produces reference architectures ready for implementation and rollout. The team is comprised of senior architects with subject matter expertise spanning HPC compute, storage, networking, and orchestration. 

As the HPC Network Architect, you will own the architecture of highly scalable, highly available, and globally distributed networks that support large-scale research and AI/ML workloads. You will assess existing and emerging network technologies against real business and product needs, and turn architectural decisions into clear direction that engineering teams can execute against with confidence. 

You will work closely with Storage, Compute, and Orchestration architects, along with engineering teams and hardware vendors, to ensure every networking decision fits into a coherent, future-proof HPC platform. You will also establish a data-driven approach to continuously evaluating operational needs and constraints, proactively identifying opportunities to improve performance and resiliency. 

Success in this role looks like bringing rigor and clarity to some of the most demanding networking challenges in HPC, while staying ahead of a fast-moving technology landscape and mentoring engineering teams along the way. 

RESPONSIBILITIES 

• Design the architecture of highly scalable, highly available, and globally distributed networks to support large-scale research workloads. 

• Assess existing and emerging networking technologies against business and product needs. 

• Guide and drive execution by bringing clarity of the architecture to engineering teams and ensuring high-quality engineering standards are followed. 

• Collaborate with storage, compute, and orchestration architects to propose coherent, complete, and future-proof HPC solutions. 

• Establish a data-driven approach to continuously evaluate operational needs and constraints and proactively propose improvements. 

• Define and evangelize network architecture standards and best practices across engineering teams. 

• Stay current with emerging technologies and approaches and apply new knowledge across disciplines. 

REQUIREMENTS 

• Bachelor's or Master's degree in Computer Science, Engineering, Physics, or a related technical field, with 10-12 years of experience. 

• Strong working knowledge of network technologies and architectures, including Ethernet and InfiniBand, with hands-on experience applying them in an HPC context. 

• Hands-on experience with high-speed fabric solutions, particularly InfiniBand and NVLink, and ideally Ethernet (RoCE) and Omni-Path. 

• Experience with network offloading and hardware acceleration technologies and their role in large-scale / exascale systems. 

• Solid grasp of packet switching, routing algorithms, flow control, and congestion management, with the judgment to apply the right solution for optimal network performance. 

• Solid grasp of networking security and network virtualization, and their integration with IaaS and Kubernetes. 

• Hands-on lab experience running benchmarks and test jobs on pre-production / unproven hardware in a testing environment. 

• Experience designing or contributing to HPC clusters and parallel computing environments, with proficiency in Linux kernel tuning, system-level optimization, or performance profiling. 

• Experience with emerging network trends such as CXL, PCIe Gen 6, or DPUs is a plus.
