About the role
Anthropic runs one of the largest and fastest-growing infrastructure fleets in the industry, spanning multiple accelerator families, CPU families, and clouds. The Capacity Engineering team makes sure every infrastructure resource is accounted for, well utilized, and efficiently allocated. You will build the production systems behind this work: data pipelines that ingest and normalize telemetry from different cloud environments, observability tooling for real-time fleet visibility, and performance instrumentation that measures how efficiently workloads use their hardware. You will work with research engineering, infrastructure, inference, and finance teams on decisions around one of Anthropic’s largest areas of spend.
This is a pipeline role feeding four focus areas, and you will concentrate mainly on one:
Data platform: pipelines that ingest utilization telemetry and normalize billing across cloud providers into BigQuery
Planning: real-time fleet visibility, cluster health tooling, capacity planning, and alerting
Efficiency: measuring and improving how well each major workload uses its hardware
Attribution and forecasting: connecting fleet cost to business activity and building a defensible compute plan
Key Responsibilities
Build the planning and allocation stack, including cross-region and cross-provider placement, guardrails, queueing, and occupancy KPIs
Drive efficiency programs such as stranding and rightsizing, unused capacity recovery, and job-level utilization across training, inference, and eval
Own attribution and forecasting by reconciling billing across ten-plus providers against telemetry and internal systems, then turning demand signals and research roadmaps into a compute plan
Build the data platform with ownership of completeness, latency SLOs, and gap detection, including integrating each new provider
Operate Kubernetes-native systems at scale, including collection agents, workload labeling, and taint, reservation, and scheduling behavior
Treat outputs as a product by gathering requirements, defining schema contracts, and designing for consumers from research engineers to a CFO, including on-call and SLOs
Requirements
Strong track record building and operating production systems (hands-on engineering with a devops flavor)
Production-quality Python and SQL, including BigQuery SQL, table-valued functions, and views
Deep experience with at least one major cloud provider (AWS, Google Cloud, or Azure) and its operations
Experience with Prometheus, PromQL, and Grafana, including writing recording rules and building monitoring that engineering teams rely on
Ability to gather your own requirements and work across organizational boundaries in an ambiguous environment
Bachelor’s degree or an equivalent combination of education, training, and experience
