Staff Software Engineer

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.

• Design, build, and operate the feedback and data collection interfaces used by human annotators, domain experts, and internal researchers.
• Build and maintain the backend services, APIs, and pipelines that route model samples to humans and return structured feedback to training.
• Own the reliability, latency, and usability of systems that run continuously against live model endpoints.
• Partner with RL researchers to translate loosely specified data needs into well-scoped collection campaigns and the tooling to run them.
• Build dashboards, monitoring, and inspection tools so researchers can see data quality and throughput without asking an engineer.
• Identify and remove the bottlenecks between "we want this data" and "it's in the training mix".

• Strong full-stack engineering skills, with production experience in TypeScript/React on the frontend and Python on the backend.
• Experience designing and operating backend services and data pipelines that other teams depend on.
• A track record of owning projects end-to-end, from an ambiguous brief to something in production that people use.
• Comfort working directly with technical stakeholders whose needs change week to week, and the judgment to push back when something isn't worth building.
• Effective use of AI tools in your own day-to-day work.
• Care about the societal impacts of your work.

• Annual Salary: $320,000 — $405,000 USD
• Location-based hybrid policy: Currently, we expect all staff to be in one of our offices at least 25% of the time. However, some roles may require more time in our offices.
• Visa sponsorship: We do sponsor visas! However, we aren't able to successfully sponsor visas for every role and every candidate. But if we make you an offer, we will make every reasonable effort to get you a visa, and we retain an immigration lawyer to help with this.
