Anthropic STEM Fellowship 2027 (up to $167,000)

Deadline: October 28, 2026

Applications are open for the Anthropic STEM Fellowship 2027. The Anthropic STEM Fellows Program brings researchers and experts from across science and engineering into Anthropic for four months to take on the grand challenges of their fields with Claude.

Working in small pods of Fellows from related fields, you will pair deep domain expertise with our frontier models and internal tooling to define the hardest open problems in your discipline, build the datasets and simulations that let them test and train Claude on them, and find exactly where it falls short.

They are looking for Fellows across science and engineering. Prior machine learning experience is helpful but not required. Scientific judgment and a willingness to learn quickly matter more. The first cohort of more than 20 STEM Fellows across mathematics, physics, the life sciences, and engineering, ran from June to September 2026. The problems they built now feed Claude’s training and one of our internal science evaluations.

Key Responsibilities

Key responsibilities include

Setting grand challenges for your field: identifying long-horizon open problems where Claude falls short of expert judgment, and defining what real progress on them looks like.

Building comprehensive datasets, simulations and rigorous, hard-to-game evaluations that test whether models can plan experiments, interpret data and reason about mechanisms, and systematically finding where they’re confidently wrong.

Applying Claude to open problems in your domain, using test-time compute strategies and integrating the scientific tools and software your field relies on.

Benefits

$100,000–$167,000 USD for the four-month fellowship (equivalent to $300,000–$500,000 USD annualized), and other benefits.

Eligibility

Are excited about the potential for AI to reason well about hard questions in their field where expert judgment matters.

Hands-on experience using Claude and Claude Code in your day-to-day workflow.

Hold a PhD in a STEM field and have several years of experience (eg post-doc or faculty).

Are comfortable working in a fast-paced, high-agency atmosphere for a few months and delivering concrete results.

Existing authorization to work in the United States for the duration of the program.

Application

Applications are open until October 28, 2026, and they plan to make offers by November 20. Later stages will typically include a take-home exercise and conversations with the research team about your research interests and possible project directions.
