Staff+ Software Engineer, Caching

Key Responsibilities

• Drive the technical direction for caching infrastructure used across Product and Research.
• Design, build, and operate a managed Redis fleet that scales to support millions of users across Claude's product ecosystem.
• Build client libraries and developer-facing abstractions that make correct caching the default for Anthropic engineers.
• Design and operate CDC-driven cache invalidation that keeps cached data consistent with source-of-truth databases.
• Architect caching solutions that operate across GCP, AWS, first-party deployments, and other environments.
• Optimize latency, hit rates, reliability, and cost efficiency on Anthropic's hottest paths.
• Build observability and tooling that makes cache behavior easy to understand and debug.
• Partner with product and research teams to understand access patterns and build infrastructure that accelerates their work.
• Make build-vs-buy decisions for caching technologies.

Minimum Qualifications
