Staff+ Infrastructure Engineer, Cluster InfrastructureActive$320K

The opportunity

Anthropic's Infrastructure organization is foundational to our mission of developing AI systems that are reliable, interpretable, and steerable. The systems we build determine how quickly we can train new models, how reliably we can run safety experiments, and how effectively we…

What you'll do

  • Own the technical strategy and roadmap for agent-driven cluster lifecycle: management - provisioning, updates and decommissioning

  • Partner across teams to ensure new compute capacity is ingested on time

  • Align with partner teams on physical build-out and leverage cloud solutions: to deliver high-bandwidth inter-cluster connectivity

  • Collaborate with security owners to ensure clusters are provisioned secure-by-default

  • Define and drive strategy on cluster scalability, homogeneity and fault tolerance

  • Work closely with cloud providers and internal research, inference and: product teams to shape long-term compute, data, and infrastructure strategy

What they're looking for

  • + years of software engineering experience, including time as a technical lead setting direction for a team
  • Experience operating large-scale compute infrastructure at hyperscale (100+ clusters, 10K+ nodes)
  • Depth in one or more of: Kubernetes internals, cluster provisioning and management systems, cluster orchestration systems (Mesos, Borg-like)
  • Experience with cloud networking: VPC design and peering, Shared VPC/Transit Gateway, Cloud Interconnect/Direct Connect, Cloud NAT, cross-cloud private connectivity, BGP and route control, edge load balancing and DDoS mitigation (Cloud Armor / AWS Shield)
  • Experience with cluster and host networking: CNI (Cilium), eBPF, NetworkPolicy, multi-NIC, sFlow, service mesh (Istio/Envoy/Linkerd, mTLS)
  • Experience with cluster security: pod security standards and admission control, RBAC and least-privilege IAM, node and container hardening, supply-chain/image provenance
  • Deep experience with infrastructure-as-code (Terraform, Atlantis), workflow: orchestration (Temporal, Argo Workflows)
  • Skill in quickly understanding systems design tradeoffs and keeping track of rapidly evolving software systems
