• Troubleshoot and resolve complex network issues impacting HPC workloads and services, minimizing downtime and maintaining service reliability.
• Configure, maintain, and upgrade enterprise-grade firewalls, VPNs, ACLs, and routing protocols (e.g., BGP, OSPF) while ensuring secure and efficient network operations.
• Provide network support and integration for HPC platforms, including Slurm, Kubernetes, and bare-metal provisioning environments.
• Support IP address management, VLAN configuration, network segmentation, and security zoning aligned with operational and compliance standards.
• Develop and maintain automation scripts and infrastructure-as-code solutions using tools such as Python, Ansible, and Terraform to improve operational efficiency.
• Collaborate closely with compute, storage, security, and site reliability teams to support scalable and resilient network solutions for AI and HPC workloads.
• Maintain network documentation, operational runbooks, configurations, and change records in accordance with ITIL and operational standards.
• Participate in on-call rotations and support incident management, change activities, and root cause analysis (RCA) processes.
• Contribute to continuous improvement initiatives by identifying recurring operational challenges and recommending optimization opportunities.
• Provide technical guidance and knowledge sharing within the engineering team.
• Ensure adherence to security policies, operational procedures, and audit requirements.
