Job description

The Center for AI Safety (CAIS) is a leading research and advocacy organization focused on mitigating societal-scale risks from AI. We address AI's toughest challenges through technical research, field-building initiatives, and policy engagement, along with our sister organization, Center for AI Safety Action Fund.
As a Research Engineer here, you'll work at the intersection of cutting-edge ML research and reliable engineering. You'll design and run experiments on large language models, build the tooling needed to train and evaluate models at scale, and turn results into publishable research. You'll collaborate closely with CAIS researchers and external academic and commercial partners, using our compute cluster to run large-scale training and evaluation. The work spans areas like AI honesty, robustness, transparency, and trojan/backdoor behaviors, aimed at reducing real-world risks from advanced AI systems.
Key Responsibilities Include:
  • Own end-to-end research experiments.
  • Train and fine-tune large transformer models across domains.
  • Build and maintain datasets and benchmarks.
  • Run distributed training and evaluation at scale.
  • Write and ship research, collaborating with co-authors, and supporting submissions of papers to top conferences.
  • Collaborate with researchers and external partners while contributing to shared research direction and responding quickly in research cycles.
  • Support research infrastructure as needed, such as internal tooling, documentation, and reproducibility practices for the team.

You might be a good fit if you:
  • Are a current PhD student or researcher 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.

$140,000 - $200,000 a year
Benefits:
Health insurance for you and your dependents
401K plan + 4% matching
Unlimited PTO
Lunch and dinner at the office
