HPC Network Architect

Job Title: HPC Network Architect – Data Center Specialist

Location: Anywhere in EU
Employment Type: Full-time / Part time / Contract
Department: IT Infrastructure / High Performance Computing

Position Summary:

We are seeking a highly skilled HPC Network Architect with strong experience in data center infrastructure to design, implement, and optimize high-performance networking solutions. The ideal candidate will possess deep technical knowledge of HPC workloads, low-latency/high-bandwidth networking (e.g., InfiniBand, RoCE), and scalable data center architectures. You will collaborate with system architects, data scientists, and IT operations teams to ensure robust, high-throughput computing environments that support demanding applications in research, AI/ML, simulations, and data analytics.

Key Responsibilities:

• Design and architect end-to-end HPC network infrastructures , including interconnects, fabric topologies, and routing strategies.
• Define and implement high-speed, low-latency networks (e.g., InfiniBand, RoCE, 100/400GbE).
• Integrate HPC clusters into modern data center environments with high availability and scalability.
• Develop and maintain network policies, security models, and monitoring tools for HPC environments.
• Evaluate emerging networking technologies and recommend enhancements to improve performance and efficiency.
• Collaborate with data center engineers on power, cooling, cabling, and space planning for HPC systems.
• Troubleshoot and resolve network bottlenecks and performance issues in large-scale compute environments.
• Work with vendors and OEMs to ensure proper support and integration of HPC networking equipment.
• Document network designs, configurations, and procedures.

Qualifications:

Required:

• Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field.
• 8+ years of experience in network engineering, with 3+ years in HPC environments .
• Strong hands-on experience with InfiniBand, Ethernet (40/100/400GbE), RDMA, RoCE .
• Expertise in network design, fabric management, and traffic optimization for HPC workloads.
• Experience with data center design , power/cooling planning, and rack integration.
• Familiarity with Linux system administration and automation (e.g., Ansible, Python, Bash).
• Solid understanding of TCP/IP, BGP, OSPF, multicast, QoS, and software-defined networking.

Preferred:

• Experience with Slurm , PBS , or other HPC job schedulers.
• Familiarity with cloud and hybrid HPC models (e.g., AWS ParallelCluster, Azure CycleCloud).
• Certifications such as CCNP/CCIE, HCIA/HCIP, or equivalent .
