Senior Network Operations Engineer

As a Senior Network Operations Engineer at Together AI, you are our front-line responder for break/fix incidents—owning alert triage, collaborating with SRE and MLOps teams, and driving rapid resolution to keep our global network and platform running smoothly. You combine strong operational discipline with hands-on troubleshooting and a bias for automation. Beyond traditional networking, you’ll work hands-on with Kubernetes and Slurm to diagnose issues that span infrastructure, container networking, and HPC job fabrics.

You’re fluent in routing/switching and network security fundamentals, comfortable on Linux, and thrive in fast-moving environments where clear communication and crisp execution matter. You’ll improve monitoring, runbooks, and recovery playbooks to reduce MTTA/MTTR and prevent repeat incidents.

Outstanding problem-solving abilities and a solid understanding of fundamental network theory are also critical to your success.

Responsibilities

• Serve as first responder for network alerts and incidents: assess impact, prioritize, mitigate, and escalate as needed to SRE/MLOps/Network Engineering.
• Own end-to-end incident lifecycle: detection, triage, containment, remediation, comms, and post-incident reviews with clear timelines and action items.
• Monitor network health and capacity across routing/switching, firewalls, and data center fabrics; tune alert thresholds and dashboards to reduce noise.
• Troubleshoot L2–L4 issues (ARP, VLAN/VXLAN/EVPN, routing protocols, ACLs/NAT, DNS, TLS termination, QoS) using packet capture and flow/telemetry tools.
• Execute standard changes (MOPs) and emergency changes with rigorous change control and validation; document outcomes and update runbooks.
• Operate multi-cluster add-ons (e.g., MetalLB/Traefik/NGINX), observe health via Prometheus/Grafana/Loki, and tune alerts to reduce noise.
• Debug CNI/data plane (e.g., VXLAN/EVPN, iptables/nftables, network policies), kube-proxy/iptables mode, CoreDNS, Services (ClusterIP/NodePort/LoadBalancer), and Ingress/EGRESS.
• Maintain accurate network documentation: diagrams, inventories, IPAM, device configs, and topology state.
• Improve operational excellence: automate repetitive tasks, enhance self-service tooling, and contribute to SLOs, error budgets, and reliability roadmaps.
• Participate in a shared on-call rotation providing 24×7 coverage for critical services.

Requirements

• 3+ years in a NOC/Network Operations or Network Support role for large-scale data center or service provider-style environments (hybrid/on-prem + cloud).
• Solid understanding of TCP/IP and core protocols: BGP, OSPF/IS-IS, VLAN, VXLAN, EVPN, ACLs/NAT, DHCP, DNS, and QoS.
• Proficiency with troubleshooting tools: Wireshark/tcpdump, mtr/traceroute, nmap, curl, iperf; comfortable on Linux for diagnostics and log analysis.
• Experience operating multi-vendor networks (e.g., Arista, Cisco, Juniper, NVIDIA/Mellanox) and load balancers/firewalls.
• Familiarity with AWS/GCP/Azure networking concepts (VPC/VNet, IGW/NATGW, peering, PrivateLink, routing, security groups).
• Strong scripting/automation fundamentals (e.g., Bash/Python), and comfort with Git-based workflows for config versioning and change reviews.
• Clear, concise communicator—able to write incident timelines, RCAs, and user-facing updates under time pressure.

Preferred

• Knowledge of RoCE and Infiniband protocols a plus
• Hands-on Kubernetes troubleshooting experience: CNI fundamentals (policies, encapsulation), Services/Ingress, DNS (CoreDNS), kube-proxy, and container runtime basics a huge plus
• Understanding of AI training workloads and the demands they exert on networks a plus
