About the role

Role focusing on scaling and operating Anthropic's Kubernetes-based accelerator fleets, extending the scheduler, and building core cluster services to support large-scale ML workloads across multiple clouds and datacenters.

Responsibilities

  • Own, operate, and extend the Kubernetes scheduler for Anthropic's accelerator fleets, including custom scheduling plugins and policies for gang scheduling, topology awareness, and preemption
  • Scale the Kubernetes control plane (apiserver, etcd, controller-manager) to support clusters far beyond typical limits, and find the next bottleneck before it finds us
  • Design, build, and operate core cluster services such as service discovery that every workload in the fleet depends on
  • Build and maintain custom controllers, operators, and CRDs
  • Partner with research, training, and inference to understand workload shapes and turn their requirements into platform capabilities
  • Collaborate with cloud providers on required features and escalations
  • Participate in on-call, lead incident response, and design processes (postmortems, runbooks, SLOs) that help the team avoid repeating failures

Qualifications

  • Significant software engineering experience building and operating production distributed systems
  • Proficiency in at least one systems-appropriate language (e.g., Go, Python, Rust, or C++)
  • Deep, hands-on Kubernetes experience (well beyond "user of”) into scheduler, controllers, apiserver, or operating large multi-tenant clusters
  • Demonstrated ability to debug complex issues across the stack, from API behavior down to node and network-level root causes
  • A track record of designing for reliability, correctness, and clear failure semantics in systems other engineers depend on
  • Strong written and verbal communication; comfort building consensus with internal stakeholders
