Job Description
We are seeking a highly skilled Senior HPC Networking Engineer to design, deploy, manage, and troubleshoot high-performance networking environments. The ideal candidate will have deep expertise in InfiniBand technologies, strong general networking knowledge, and hands-on experience with Fortinet solutions. You will play a critical role in ensuring the performance, reliability, and scalability of HPC infrastructure.
Key Responsibilities:
* Design, deploy, and maintain high-performance network infrastructures for HPC environments, with a strong focus on InfiniBand fabrics. * Troubleshoot complex network issues across InfiniBand and Ethernet environments, ensuring minimal downtime and optimal performance. * Manage and optimize InfiniBand components, including switches, HCAs, subnet managers, and fabric configurations. * Perform performance tuning, monitoring, and capacity planning for HPC networking systems. * Implement and maintain network security using Fortinet solutions (FortiGate, FortiManager, FortiAnalyzer). * Diagnose and resolve issues related to routing, switching, latency, and throughput across hybrid network environments. * Collaborate with compute, storage, and platform teams to support HPC workloads and cluster operations. * Develop and maintain documentation for network architecture, configurations, and operational procedures. * Participate in on-call rotations and provide escalation support for critical incidents. * Lead or contribute to network upgrades, migrations, and new deployments.
Qualifications
Required:
* 5+ years of experience in network engineering, with a focus on HPC or data center environments. * Strong hands-on experience with InfiniBand technologies (e.g., Mellanox/NVIDIA). * Solid understanding of networking fundamentals: TCP/IP, routing protocols (BGP, OSPF), VLANs, QoS, and network design. * Proven experience deploying and troubleshooting Fortinet solutions (FortiGate, FortiManager, VPNs, firewall policies). * Experience with network performance analysis and troubleshooting tools. * Familiarity with Linux systems and scripting for automation (e.g., Bash, Python). * Strong analytical and problem-solving skills.
Preferred:
* Experience with large-scale HPC clusters or AI/ML infrastructure. * Knowledge of RDMA, MPI, and low-latency networking concepts. * Certifications such as FCSS/FCNSP (Fortinet), CCNP/CCIE, or equivalent. * Experience with automation and Infrastructure as Code tools (e.g., Ansible, Terraform).
Soft Skills:
* Strong communication and collaboration skills. * Ability to work independently and handle complex technical challenges. * Detail-oriented with a proactive approach to problem-solving.
Additional Information
What We Offer:
* Operate some of the most advanced AI infrastructure environments in production today. * Work with the latest NVIDIA GPU technologies, Kubernetes platforms, and high-performance networking environments. * Help define operational standards and reliability practices for next-generation AI infrastructure services. * Influence the adoption of AI-powered operational capabilities through k0rdent AI. * Work alongside highly skilled engineers solving complex infrastructure and platform challenges at scale. * Join a growing organisation investing heavily in AI infrastructure, platform services, and operational innovation.
