Software Engineer, Languages

Overview

Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems.

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.

Responsibilities

• Design and build foundational language infrastructure for Python, Rust, and / or Go that supports both AI research workflows and production-scale systems
• Define and implement language ecosystem standards, best practices, tooling, libraries, and frameworks that ensure safety, performance, and exceptional developer productivity across diverse AI workloads
• Establish language-specific CI / CD pipeline integration, testing frameworks, and deployment strategies optimized for AI development cycles
• Partner extensively with infrastructure teams to ensure seamless integration between language-specific tools and broader platform services, such as debugging Kubernetes issues, optimizing node instance types for performance, and collaborating on cross-cutting infrastructure challenges
• Collaborate closely with research and engineering teams to understand emerging requirements and translate them into robust, scalable language infrastructure, including cross-language interoperability solutions
• Drive technical strategy for language adoption, migration paths, large-scale cross-cutting changes, and ecosystem evolution as Anthropic scales, while mentoring engineers and researchers on language best practices
• Lead incident response and troubleshooting for language-related issues across research and production environments
