Senior Network & Site Reliability Engineer

What You'll Do

• Architect and operate scalable, secure network architecture for high-security requirements and large-scale machine learning workloads.
• Own network device configuration management end to end, ensuring consistency and reliability across the fleet.
• Improve system and network reliability and performance through automation, observability, and proactive capacity planning.
• Implement and manage complex network protocols and connectivity, including BGP, VPNs, and WAN circuits and external peering.
• Build and maintain comprehensive monitoring, alerting, and incident response — SLOs, runbooks, and on-call rotations — and drive post-incident analysis and continuous improvement.
• Ensure security, compliance, and operational readiness across our network and cloud infrastructure.
• Partner across engineering and data science to drive a culture of performance and reliability.

What Will Help You Succeed

• 8+ years in network or infrastructure engineering, including 5+ years in datacenter operations and/or systems and network administration.
• A strong background in network security, architecture, design, and operations.
• Extensive hands-on experience with network devices (firewalls, switches, load balancers) and large-scale architectures and protocols — BGP, QoS, MPLS, and IPsec VPNs.
• Experience designing and operating modern datacenter network fabrics (spine-leaf, EVPN/VXLAN, ECMP).
• Network automation and IaC tooling (Ansible, Terraform, Nornir, or similar), plus IPAM/DCIM platforms (NetBox, Infoblox, or similar).
• WAN engineering — carrier circuit provisioning and external network peering.
• Familiarity with Kubernetes networking (CNI plugins, ingress, service networking, network policy) and strong operational experience with Linux-based production infrastructure.
• Experience with monitoring and observability stacks (Prometheus, Grafana, Datadog, ELK, OpenTelemetry).
• Solid scripting (Python, Bash) to debug complex network and system issues and automate solutions, plus excellent cross-functional communication.

Also Helpful

• NVIDIA networking technologies — Cumulus Linux, InfiniBand, Spectrum-X, and BlueField DPUs.
• Familiarity with data-intensive platforms (Spark, Airflow, Kafka) and storage network protocols (NFS, LustreFS, iSCSI).
• Security practices for applications and infrastructure, and experience in high-compliance or SOC 2 environments.
