How to apply for Conceptual Reasoning Fellow

About Anthropic

Anthropic is a frontier AI research and product company working on alignment, policy, and security. The company posts specific high-impact opportunities, and it explicitly notes that it does not necessarily recommend working at other positions at Anthropic. Candidates should read Anthropic's stated concerns about doing harm by working at a frontier AI company before applying.

About the role

The Conceptual Reasoning Fellow program brings researchers and experts from philosophy, cognitive science, economics, policy, and law into Anthropic for four months. Fellows work alongside research teams, pairing domain expertise with frontier models and internal tooling to evaluate, improve, and apply Claude's capabilities in their field. The role is remote within the US and pays $100,000–$167,000 for the four-month term.

A typical day

The posting does not describe a daily routine. Expect to work on a scoped project with mentorship from Anthropic researchers, using frontier Claude models and internal evaluation tooling, alongside a cohort of incoming Fellows. Ask the hiring team how the four months are structured and how time is split between project work, mentorship, and cohort collaboration.

Who Anthropic is looking for

• Has deep domain expertise in one of the named fields: philosophy, cognitive science, economics, policy, or law.
• Has built judgment on questions that have no single checkable answer, through years of research or practice.
• Can scope and execute a concrete project matched to their background within a four-month window.
• Is willing to work directly with frontier models and internal evaluation tooling, and to collaborate with a cohort of incoming Fellows and Anthropic researchers.

Tips for this application

• Propose a concrete, scoped four-month project in your application that connects your domain to evaluating, improving, or applying Claude's capabilities.
• Name the specific field you come from (philosophy, cognitive science, economics, policy, or law) and give evidence of the judgment you have built in it.
• Address Anthropic's stated concerns about working at a frontier AI company directly, since the job posting links to them.
• Show familiarity with Anthropic's stated mission: reliable, interpretable, and steerable AI systems that are safe and beneficial.
• Note that this is a specific posted opportunity and that Anthropic does not necessarily recommend other positions there; keep your application focused on this fellowship.

What to cover in your cover letter

State your domain field and the concrete judgment you have built in it. Describe a scoped project you could complete in four months with frontier models and internal evaluation tooling. Explain how your work would evaluate, improve, or apply Claude's capabilities in your field. Address the concerns Anthropic raises about working at a frontier AI company.

Research before applying

• Read Anthropic's mission statement and its descriptions of work on alignment, policy, and security.
• Read the 80,000 Hours career review on working at an AI lab, which the job posting links to.
• Look into Anthropic's posted work on Claude and any public material on its internal evaluation tooling.
• Check what Anthropic has published in your specific field (philosophy, cognitive science, economics, policy, or law).

Likely interview topics

Based on the job description, expect questions about:

• Your proposed four-month project: scope, method, and what success would look like.
• How you reason about questions in your field that have no single checkable answer.
• How you would evaluate or improve Claude's capabilities in your domain.
• Your view on Anthropic's mission of reliable, interpretable, and steerable AI, and on the concerns the company links to about working at a frontier AI lab.
• How you would collaborate with a cohort of Fellows and Anthropic researchers within four months.

Common mistakes to avoid

• Submitting a generic research statement instead of a concrete, scoped four-month project.
• Ignoring the concerns Anthropic raises about working at a frontier AI company.
• Applying as if this were a general Anthropic role rather than this specific posted fellowship.
