Anthropic's Infrastructure organization builds and operates the distributed systems that train, serve, and secure our AI models. This includes data pipelines, some of the largest Kubernetes clusters in the world, and the databases, observability, and developer tooling that every other team depends on. As a Staff Software Engineer on the Infrastructure team, you'll scope and lead complex, multi-month infrastructure projects, make architectural decisions, and work with research and product teams to build systems that keep pace as their needs change.

• Independently scope and lead complex, multi-month infrastructure projects from ambiguous starting points to production systems.
• Make architectural decisions that shape the foundation other engineers and teams build on.
• Drive alignment on technical direction across teams.
• Partner with research and product teams to understand infrastructure and compute needs and turn them into technical designs.
• Own the reliability, scalability, and security of the systems you build.
• Set technical strategy and standards for your team's infrastructure.
• Build and improve operational processes such as incident response, postmortems, and on-call rotations.
• Mentor other engineers and help raise the technical bar.

• Experience designing, building, and operating large-scale distributed systems or infrastructure in production.
• A history of independently scoping and delivering complex, ambiguous, multi-month technical projects.
• Experience making architectural decisions that other engineers and teams build on.
• Strong software engineering fundamentals and proficiency in at least one programming language (e.g., Python, Rust, Go, or Java).
• Experience with modern cloud infrastructure, including Kubernetes and infrastructure-as-code, on AWS and/or GCP.
• Strong written and verbal communication skills.

• 10+ years of software engineering experience, not including internships.
• Experience with machine learning infrastructure such as GPUs, TPUs, or Trainium, and associated networking like NCCL.
• Low-level systems experience, such as Linux kernel tuning or eBPF.
• Background in security or privacy engineering best practices.
• Prior experience as a technical lead or mentor.
