The role

You will design and operate the global network and reliability layer for a private supercomputer. This involves working across networking, systems, automation, observability, and reliability engineering to scale the platform.

What you will 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.
  • 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 monitoring, alerting, and incident response including SLOs, runbooks, and on-call rotations.
  • Ensure security, compliance, and operational readiness across network and cloud infrastructure.
  • Partner across engineering and data science to drive a culture of performance and reliability.

Required qualifications

  • 8+ years in network or infrastructure engineering.
  • 5+ years in datacenter operations and/or systems and network administration.
  • 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).
  • Experience with 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).
  • 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.

Nice to have

  • 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.

Benefits

  • Meaningful equity
