Staff Software Engineer, Infrastructure (Distributed Systems)

About the role

Anthropic’s Infrastructure organization builds and operates the large‑scale distributed systems that train, serve, and secure our AI models. As a Staff Software Engineer you will lead multi‑month projects, define architecture, and partner with research and product teams to keep pace with evolving compute needs.

Key responsibilities

• Scope and lead complex, multi‑month infrastructure projects from ambiguous start to production.
• Make architectural decisions that shape the foundation for other engineers and teams.
• Drive technical alignment across teams and resolve ambiguous problem spaces.
• Partner with research and product groups to translate compute requirements into designs.
• Own reliability, scalability, and security as systems grow in usage and complexity.
• Set technical strategy and standards for team infrastructure.
• Improve operational processes such as incident response, post‑mortems, and on‑call rotations.
• Mentor engineers and raise the technical bar across the team.

Required profile

• Experience designing, building, and operating large‑scale distributed systems in production.
• Proven ability to independently scope and deliver complex, ambiguous, multi‑month projects.
• Strong software engineering fundamentals with proficiency in at least one language (e.g., Python, Rust, Go, Java).
• Experience with modern cloud infrastructure, Kubernetes, and infrastructure‑as‑code on AWS and/or GCP.
• Excellent written and verbal communication skills for driving alignment across teams.
