Join a small applied research team working directly with frontier AI research organizations on challenging post-training problems. This research-first role focuses on reinforcement learning, training data, and experiments that improve model capabilities.
How do we know whether a model is safe - and how do we know whether the systems we built to catch misuse actually catch it? We measure model behavior across misuse, prompt injection, and user well-being to inform training and deployment decisions.
Set the technical vision and roadmap for model training and serving, with reusable interfaces to data and feature infrastructure. Lead architectures for distributed training, fine-tuning, distillation, evaluation, and high-scale CPU/GPU inference.
Join a healthtech team building decision-support tools for clinical care. You will own reinforcement learning environments and evaluations that help training teams develop systems for complex clinical reasoning, with work informed by clinical experts.
We are seeking a Member of Technical Staff, AI Researcher to help turn complex, real-world workflows into the evaluation frameworks, reinforcement learning environments, and feedback systems needed to advance frontier AI.
