Research Engineer/Scientist

The RoleAs a Research Engineer (RE) or Research Scientist (RS) at CAIS, you'll lead and execute high-impact research that advances the safety and reliability of frontier AI systems. This is the general posting for both roles—if you're interested in either, apply here, and we'll determine which is the better fit based on our judgment during the process.You will design and run experiments on large language models, build the tooling to train and evaluate models at scale, and turn results into publishable research. You'll work closely with CAIS researchers and external academic and commercial partners, using our compute cluster to run large-scale training and evaluation.Our work centers on empirical deep learning research with large language models and/or multimodal models. If your background is primarily theoretical, this role may not be a good fit.Research directions at CAIS are set by our Research Director, who selects and prioritizes projects for their importance, neglectedness, and timeliness—a major reason our work has been so impactful. In practice, this means that you will consistently be working on interesting, high-impact problems, with substantial freedom in how you pursue them: designing and running experiments, iterating, and chasing the threads you find most promising.What You'll DoOwn research experiments end-to-end.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.Mentor, guide, and support others on the team.What We're Looking ForHave co-authored multiple papers published at a top ML conference venues (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. Alternatively, have made meaningful research contributions at a leading AI lab.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 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.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, and take ownership of your part of a project.Salary Range$140,000 - $200,000 annually, based on experience.BenefitsHealth insurance for you and your dependents401K plan + 4% matchingUnlimited PTOLunch and dinner at the officeAnnual Professional Development StipendAccess to some of the top talent working on technical and conceptual research in AI safetyReferral ProgramKnow someone who could be a great fit for this role?
