• Architect caching solutions operating 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-versus-buy decisions for caching technologies.

Requirements

• Significant experience building and operating production distributed systems as a software engineer.
• Deep knowledge of caching architectures, including invalidation strategies, consistency tradeoffs, and failure modes.
• Production experience operating Redis, Memcached, or similar in-memory data stores.
• Proficiency in at least one systems programming language, such as Go, Rust, Java, or C++, or Python at scale.
• A track record of leading large, complex infrastructure projects as an engineer or technical lead.
• Ability to balance rapid development with the reliability needs of production systems.
• Strong technical leadership and cross-functional collaboration skills.
• Preferred: 10+ years building and scaling distributed infrastructure, with 3+ years leading large-scale projects or teams.
• Preferred: Experience building managed infrastructure platforms or internal services consumed by many engineering teams.
• Preferred: Experience with change data capture, including Debezium or similar technologies, or streaming data infrastructure.
• Preferred: Experience operating Redis Cluster, Valkey, ElastiCache, Memorystore, or similar managed offerings at scale.
• Preferred: Experience designing client libraries or SDKs for internal infrastructure.
• Preferred: Experience scaling infrastructure during periods of rapid growth at high-growth companies.
• Preferred: Experience with multi-cloud or hybrid-cloud deployments.
• Preferred: Contributions to caching systems, database internals, or related open-source projects.
• Prior AI/ML infrastructure experience is not required.
• Minimum education: Bachelor's degree or an equivalent combination of education, training, and experience.
