Researcher, Safety Training at OpenAI in San Francisco

ABOUT THE TEAM Safety Research at OpenAI is responsible for ensuring our most capable models can be safely deployed in the real world. The Safety Training team develops the research and engineering methods that shape model behavior through post-training, reinforcement learning, evaluation, and deployment feedback. Our work focuses on making models helpful, reliable, and aligned with safety policies across model types, modalities, and product surfaces. We work across both longer-term safety research and the core post-training work needed to improve production models. ABOUT THE ROLE We are seeking researchers to advance safety training for OpenAI’s models. You will develop methods that improve model behavior after pretraining, including RLHF, RLAIF, DPO, PPO, preference optimization, adversarial training, synthetic data generation, safety evaluations, and model behavior analysis. This role is highly cross-functional. You will work with core training teams, product teams, policy, legal, trust and safety, and domain experts to identify risks, design interventions, train models, evaluate outcomes, and launch safety improvements in OpenAI products. IN THIS ROLE, YOU WILL: - Conduct research on safety post-training methods, including RLHF, RLAIF, DPO, PPO, reward modeling, adversarial training, synthetic data, and scalable oversight - Develop and implement model training…
