## Description

## Job Overview

We're looking for a Staff Infrastructure Engineer to join our Cluster Infrastructure team at Anthropic. As a Staff engineer on this team, you'll set the technical direction for how Anthropic brings compute online - at a moment when the scale of that compute is growing faster than at almost any company in the world.

## Responsibilities

- 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

- Establish and evolve operational-excellence practices: incident response, postmortem culture and on-call health

- Support the growth of engineers around you through technical mentorship and coaching

## Requirements

- Deep expertise in distributed systems, reliability, and cloud platforms (e.g., Kubernetes, IaC, AWS/GCP/Azure)

- Strong proficiency in at least one systems language (e.g., Rust, Go, or Python), IaC proficiency with Terraform

- Track record of leading complex, multi-quarter technical initiatives spanning multiple teams or systems

- Ability to build alignment across senior stakeholders and communicate effectively at all levels

## Preferred Qualifications

- 8+ 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

## Compensation

The annual compensation range for this role is $320,000-$4,050,000 USD.

## Logistics

- Minimum education: Bachelor’s degree or an equivalent combination of education, training, and/or experience

- Required field of study: A field relevant to the role as demonstrated through coursework, training, or professional experience

- Minimum years of experience: Years of experience required will correlate with the internal job level requirements for the position

- Location-based hybrid policy: Currently, we expect all staff to be in one of our offices at least 25% of the time. However, some roles may require more time in our offices.

- Visa sponsorship: We do sponsor visas!

## Benefits

We offer competitive compensation and benefits, optional equity donation matching, generous vacation and parental leave, flexible working hours, and a lovely office space in which to collaborate with colleagues.
