Anthropic STEM Fellow - Remote US Contract Role — Columbus

Headquarters: Remote-Friendly, United States; San Francisco, CA

About Anthropic

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.

Program Overview

Some of our world's grand challenges — from resolving long-open problems in mathematics to designing medicines for neglected diseases — require deep expert judgment that today's AI still lacks. We're working toward an AI scientist: a system capable of the long-horizon reasoning and experimental judgment needed to push the frontier on problems like these. We believe frontier AI, developed safely, can meaningfully accelerate progress across science and engineering. Getting there requires close collaboration with people who have spent years at the frontier of their fields.

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 us test and train Claude on them, and find exactly where it falls short.

We're 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.

Our 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.

What to Expect:

• A place in a small pod of Fellows working on related problems in your domain. Your pod meets weekly with Anthropic researchers to share methods, pressure-test ideas, and build on each other's work.
• A grand challenge at the frontier of your field: an ambitious, open-ended problem scoped with our research team so you can make real progress in four months.
• Access to frontier Claude models and internal evaluation tooling.

Compensation:

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

Key Responsibilities

• 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, 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.

Minimum Qualifications

• 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 (e.g., post-doc or faculty).
• 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.

Logistics – Fellows

• The program runs from January 12th to May 8th, 2027, and is full-time for the duration; some fellowships may be considered for an extension.
• Applications are open until October 28, 2026, and offers are planned by November 20th. Later stages will typically include a take-home exercise and conversations with our research team about your research interests and possible project directions.
• All Fellows must attend a one-week in-person orientation in San Francisco.
• The default location is San Francisco. Remote engagements within the United States will be considered in certain circumstances.
• We are not currently able to sponsor visas for Fellows. To participate, you need to have or independently obtain full-time work authorization in the United States.
• This is a fixed-term contract position. Fellows are engaged through an employer of record, rather than employed directly by Anthropic.

Note: The policies below apply to Anthropic's full-time roles and do NOT apply to the Fellows Program.

How We're Different

We believe that the highest-impact AI research will be big science. At Anthropic we work as a single cohesive team on just a few large-scale research efforts. We value impact — advancing our long-term goals of steerable, trustworthy AI — rather than work on smaller and more specific puzzles. We view AI research as an empirical science, with as much in common with physics and biology as with traditional efforts in computer science. We're an extremely collaborative group, and we host frequent research discussions to ensure we are pursuing the highest-impact work at any given time. As such, we greatly value communication skills.

The easiest way to understand our research directions is to read our recent research. This research continues many of the directions our team worked on prior to Anthropic, including: GPT-3, Circuit-Based Interpretability, Multimodal Neurons, Scaling Laws, AI & Compute, Concrete Problems in AI Safety, and Learning from Human Preferences.
