Join Anthropic's Languages Team as a foundational member shaping how Python, Rust, and Go are used across one of the world's fastest-growing AI companies. As we scale our engineering and research teams, we are currently seeking three team members (one each for Python, Go and Rust), who are experts in the respective languages, to help define and build the development ecosystems that power the future of AI development. You'll be responsible for the full lifecycle of how Python, Rust, and Go are used by engineers and researchers across Anthropic - from research experiments to production systems serving millions. This includes building foundational language infrastructure, defining best practices, creating tooling, and ensuring exceptional developer productivity while supporting both cutting-edge AI research and massive-scale deployment. Working at the intersection of language ecosystems and AI development, you'll tackle uniquely complex problems where your architectural decisions directly impact how thousands of engineers develop AI systems safely and efficiently. The infrastructure you build must support diverse workloads - from experimental research code to battle-tested production systems - all while maintaining the highest standards of safety, performance, and developer experience. This is an opportunity to establish the standards and foundations for how modern programming languages enable AI development at unprecedented scale, working alongside some of the brightest minds in AI research and engineering.
