Staff + Sr. Software Engineer in USA

  • Anthropic
  • Full time
  • Email
  • Seattle, WA

Responsibilities

  • Bring up inference for new model architectures and ship them to cloud platforms in lockstep with Anthropic’s first-party platform.
  • Own platform-specific integrations for new inference features such as structured sampling and prompt caching.
  • Identify and fix configuration drift, observability gaps, deployment differences, and other cross-platform inference issues at their source.
  • Design, build, and operate CI/CD infrastructure for inference servers and load balancers across cloud platforms.
  • Implement shadow traffic, performance baselines, throughput and latency checks, and correctness validation to catch regressions before production.
  • Reduce merge-to-production cycle time by making validation faster, more parallel, and cost-effective on constrained accelerator pools.
  • Analyze observability data across providers to identify performance bottlenecks, cost anomalies, and regressions, and drive remediation.

Requirements

  • Strong interest in LLM serving; prior inference or ML experience is not required.
  • Significant software engineering experience and a strong background in high-performance, large-scale distributed systems serving millions of users.
  • A track record of building automation or test infrastructure that improved release velocity or reliability.
  • Experience building or operating services on AWS, GCP, or Azure, with exposure to Kubernetes, Infrastructure as Code, or container orchestration.
  • Ability to collaborate with internal teams and external partners, learn new technologies and provider ecosystems quickly, and own problems end-to-end.
  • Preferred: experience with LLM inference optimization, batching, caching strategies, capacity-constrained scheduling, shared-resource test infrastructure, multi-region deployments, request routing, load balancing, global traffic management, and scaling infrastructure across cloud platforms.
  • Preferred: proficiency in Python or Rust.

Benefits

  • Annual base salary range of $320,000—$485,000 USD.
  • Hybrid policy currently expects staff to work from an office at least 25% of the time, with some roles requiring more office time.
  • Anthropic sponsors visas and will make every reasonable effort to obtain a visa if an offer is made, with immigration-lawyer support.
  • Competitive benefits, optional equity donation matching, generous vacation and parental leave, flexible working hours, and office collaboration space.
