Job Description

We are looking for a motivated HPC (High Performance Computing) Network Engineer to support and grow within our infrastructure team. This role is ideal for engineers with a strong foundation in networking who are interested in developing deep expertise in InfiniBand, HPC/AI infrastructure, and network security using Fortinet technologies.

You will work alongside senior engineers to operate, troubleshoot, and improve high-performance network environments, with a clear growth path toward becoming a Senior HPC Network Engineer.

Key Responsibilities:

• Support the deployment, configuration, and maintenance of InfiniBand and Ethernet network infrastructure.
• Assist in troubleshooting network issues, including connectivity, latency, and performance degradation.
• Monitor network health and performance using standard tools and assist in identifying bottlenecks.
• Work with InfiniBand technologies (switches, HCAs, subnet managers) under guidance from senior engineers.
• Support management and troubleshooting of Fortinet solutions (FortiGate, VPNs, firewall rules).
• Assist in implementing network configurations, routing, and segmentation.
• Collaborate with compute and storage teams to support HPC and AI workloads.
• Participate in incident response and operational support activities.
• Contribute to documentation of network configurations and procedures.
• Learn and adopt automation tools and practices (e.g., Ansible, scripting).

Qualifications

Required Qualifications:

• 2–4 years of experience in networking, system engineering, or infrastructure roles.
• Basic understanding of networking fundamentals (TCP/IP, routing, switching, VLANs).
• Familiarity with Linux systems and command-line tools.
• Strong willingness to learn and develop expertise in InfiniBand and HPC networking.

Preferred Qualifications:

• Exposure to InfiniBand or high-performance networking concepts.
• Familiarity with Fortinet or other firewall technologies.
• Basic scripting skills (e.g., Bash or Python).
• Understanding of monitoring tools and troubleshooting methodologies.
• Hands-on training with InfiniBand fabrics and HPC networking tools.
• Mentorship from senior engineers and involvement in complex troubleshooting scenarios.
• Opportunity to gain experience with RDMA, MPI workloads, and large-scale cluster environments.
• Path toward a Senior HPC Network Engineer role with increasing ownership and responsibility.

What We’re Looking For:

• A strong problem-solver with curiosity about how systems work at a deeper level.
• Someone eager to learn and take on increasingly complex networking challenges.
• A team player who can collaborate effectively and grow within a high-performance engineering environment.

Additional Information

• Work with some of the most advanced AI infrastructure environments in production today.
• Gain exposure to NVIDIA GPU technologies, Kubernetes platforms, and high-performance networking environments.
• Help define how next-generation AI infrastructure is operated and supported.
• Be part of a team shaping the future of AI-powered operations through k0rdent AI.
• Join a growing organisation investing heavily in AI infrastructure and platform services.
