• Capture performance goals, scalability requirements, and integration constraints to inform solution design
• Lead customer workshops, architecture reviews, and technical design sessions

HPC Network Architecture & Design

• Design and document end-to-end HPC network architectures including Ethernet, InfiniBand, RoCE, EVPN, and VXLAN fabrics
• Define scalable, low-latency network designs aligned with HPC and AI/ML workload requirements
• Develop architecture blueprints and integration strategies across compute, storage, orchestration, and security layers

Performance Optimization & Benchmarking

• Lead proof-of-concept and benchmarking initiatives to validate network performance and throughput
• Conduct network performance assessments, tuning, and optimization to eliminate bottlenecks
• Address scaling challenges such as data gravity, east-west traffic, and high-throughput demands

Observability & Monitoring

• Design and implement observability frameworks using Prometheus, Grafana, and vendor telemetry tools
• Provide visibility into network health, utilization, and performance across large-scale environments

Cross-Functional Collaboration

• Partner with engineering, product, and operations teams to refine architecture standards and delivery practices
• Collaborate with compute, storage, and platform teams to ensure integrated, workload-aware solutions
• Support multi-vendor environments and evaluate new networking technologies

Vendor & Ecosystem Engagement

• Work closely with vendors such as NVIDIA, Mellanox, Cisco, and Arista to integrate advanced capabilities
• Influence vendor roadmaps through feedback and joint evaluations
• Stay current on emerging HPC networking technologies and provide forward-looking guidance to customers

Thought Leadership & Innovation

• Represent the organization in customer engagements, workshops, and industry events
• Provide strategic insight into future networking trends including interconnect advancements and scalable architectures
• Contribute to best practices and reusable architectural patterns

Required Experience

• Proven experience in HPC networking architecture, data center network engineering, or large-scale distributed systems design
• Deep expertise with InfiniBand and RoCE, including deployment and tuning in production environments
• Strong experience designing large-scale Ethernet networks using BGP, OSPF, EVPN, and VXLAN
• Understanding of GPU communication frameworks such as MPI and NCCL and their interaction with HPC interconnects
• Experience working in Linux environments with scripting skills (Python, Bash, or PowerShell) for automation
• Experience supporting multi-vendor networking environments
• Ability to translate complex technical requirements into clear, scalable architectures
• Strong customer-facing communication skills with experience engaging both technical and executive stakeholders

Technical Skills

• Experience with network observability and telemetry platforms
• Familiarity with automation and Infrastructure-as-Code tools such as Terraform and Ansible
• Exposure to CNI plugins such as Multus, Cilium, and NVIDIA CNI for Kubernetes/HPC environments

Preferred Experience

• Experience delivering HPC or AI/ML workloads across large-scale, low-latency network environments
• Experience collaborating with vendors and influencing product direction
• Contributions to open-source HPC or networking projects
• Bachelor’s or Master’s degree in Computer Science, Networking, Engineering, or related field
• Certifications such as Cisco CCNP/CCIE, Juniper JNCIP, AWS Advanced Networking Specialty, or Red Hat RHCE
