Staff+ Software Engineer, Caching

The shape of it

In the posting’s own words

We're looking for experienced engineers to build Anthropic's cache layer as a managed service from the ground up. The Caching team is part of the Databases organization and owns the systems that keep Anthropic's hottest paths fast and correct: a managed Redis fleet, client libraries used across the company, and CDC-driven cache invalidation that solves one of distributed systems' hardest problems the right way.

What it asks for · 7

• Significant experience as a software engineer building and operating production distributed systems
• Deep knowledge of caching architectures, including invalidation strategies, consistency tradeoffs, and failure modes
• Experience operating Redis, Memcached, or similar in-memory data stores in production
• Proficiency in at least one systems programming language (e.g., Go, Rust, Java, C++) or Python at scale
• Track record of leading large, complex infrastructure projects as an engineer or tech lead
• Ability to balance moving quickly with the reliability needs of production systems
• Strong technical leadership and cross-functional collaboration skills

Also a plus

• 10+ years building and scaling distributed infrastructure, with 3+ years leading large-scale projects or teams
• Experience building managed infrastructure platforms or internal services consumed by many engineering teams
• Experience with change data capture (Debezium or similar) or streaming data infrastructure
• Experience operating Redis Cluster, Valkey, ElastiCache, Memorystore, or similar managed offerings at scale
• Experience designing client libraries or SDKs for internal infrastructure
• Experience scaling infrastructure through periods of rapid growth at high-growth companies
• Experience with multi-cloud or hybrid cloud deployments
• Contributions to caching systems, database internals, or related open source projects

What the job covers

• 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
