Senior Network & Site Reliability Engineer

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.

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.

NVIDIA networking technologies — Cumulus Linux, InfiniBand, Spectrum-X, and BlueField DPUs (this is the fabric behind our SuperPOD).

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.

You want to own mission-critical network and infrastructure end to end — from architecture to incident management — not just keep it running.

You'd rather build and automate than direct from a distance, and you want meaningful influence over how a high-performance platform scales.

Hard problems with real impact: You'll own the network and reliability layer behind systems that influence multimillion-dollar decisions at Fortune 100 companies.

Cutting-edge technology: Operate our own NVIDIA DGX SuperPOD on Grace Blackwell — one of the fastest private supercomputers in the world — and run a fabric (InfiniBand, Spectrum-X, BlueField) almost no company has in-house.

Technical autonomy: Ownership over architecture decisions and the freedom to solve hard infrastructure problems your way.

Elite team: Join top engineers who thrive on hard problems and high-impact work.

Series B momentum, real ownership: Meaningful equity at a Series B company that's raised $145M, with proven product-market fit and Fortune 100 traction.

If you only want to tell people what to build instead of building and automating alongside them, this isn't the environment for you.

You prefer companies with 100% built-out process for every detail.

You prefer static over dynamic — projects and priorities adapt as we grow. We have real paying customers and a playbook, and we still move at startup speed at Series B scale.
