Introduction

The Center for AI Safety (CAIS) is a leading research and field-building organization on a mission to reduce societal-scale risks from AI. Alongside our sister organization, the CAIS Action Fund, we tackle the toughest AI issues with a mix of technical, societal and policy solutions.

As a research engineer intern here, you will work very closely with our researchers on projects in areas such as AI security, machine ethics, AI alignment, and benchmarking AI risks. We will assign you a dedicated mentor throughout your internship, but we will ultimately be treating you as a colleague. By this we mean, you will have the opportunity to debate for your own experiments or projects, and defend their impact. You will plan and run experiments, conduct code reviews, and work in a small team to create a publication with outsized impact. You will leverage our internal compute cluster to run experiments at scale on large language models.

Timing

This application is for the full-time fall internship position. Applicants must be enrolled in university to be considered. Applications are due by June 15, 2026.

Are a current student in machine learning or a related field. Exceptional candidates with a strong publication record may be considered regardless of degree level.

Have co-authored at least one paper published at a top ML conference venue (e.g., NeurIPS, ICML, ICLR, ACL, CVPR). Workshop papers are considered, though peer-reviewed conference publications are strongly preferred. Publications in journals such as IEEE or Springer Nature are typically given less weight.

Have a track record of empirical research in AI or ML, particularly in AI safety-relevant areas (e.g. adversarial robustness, calibration, benchmarking). We weight empirical research heavily; candidates with primarily theoretical backgrounds are generally not a strong fit.

Alternatively, have made meaningful research contributions at a leading AI lab.

Are able to read an ML paper, understand the key result, and understand how it fits into the broader literature.

Are comfortable setting up, launching, and debugging ML experiments.

Are familiar with relevant frameworks and libraries (e.g., PyTorch).

Communicate clearly and promptly with teammates.

Take ownership of your individual part in a project.
