The Safety Training team develops the research and engineering methods that shape model behavior through post-training, reinforcement learning, evaluation, and deployment feedback.\nOur 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.\nAbout the Role\nWe 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.\nThis 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.\nIn this role, you will:\nConduct research on safety post-training methods, including RLHF, RLAIF, DPO, PPO, reward modeling, adversarial training, synthetic data, and scalable oversight\n\nDevelop and implement model training interventions that make models safer, more reliable, and more aligned with user intent\n\nBuild evaluations and measurement infrastructure for safety harms, high-stakes reliability failures, policy adherence, jailbreak robustness, multimodal risks, agent behavior, and domain-specific risks\n\nTranslate ambiguous safety problems into concrete research plans, datasets, training runs, evals, and product-facing improvements\n\nAnalyze model failures such as hallucination, unsafe tool use, prompt injection, privacy leakage, over-refusal, under-refusal, sycophancy, and deceptive or misleading behavior\n\nPartner with domain experts to design safety training approaches for areas like cyber, privacy, youth safety, wellbeing, and other frontier-risk domains\n\nCollaborate with research and deployment teams to ensure safety improvements are incorporated into OpenAI’s core model training and product launches\n\nYou might thrive in this role if you:\nHave hands-on experience training, fine-tuning, or post-training language models, multimodal models, or agentic systems\n\nHave experience with RL, RLHF, RLAIF, DPO, PPO, reward modeling, preference optimization, instruction tuning, or related post-training methods\n\nCare deeply about shaping model behavior in real-world systems, not only publishing research\n\nAre excited by open-ended safety problems where the right method, dataset, eval, or training objective may not be obvious at the start\n\nBring strong research judgment and strong engineering ability, including comfort running experiments, analyzing model behavior, and working with large-scale ML systems\n\nHave experience in one or more relevant domains: agents, tool use, multimodal models, cyber/security, reliability, uncertainty calibration, factuality, evals, privacy, youth safety, wellbeing, or applied alignment\n\nEnjoy collaborating across research, engineering, product, policy, legal, and trust and safety teams\n\nHold a PhD in machine learning, computer science, or a related field, or have equivalent practical research or engineering experience\n\nNice to have:\nExperience improving production model behavior through post-training or deployment feedback\n\nExperience building safety evals, automated graders, red-teaming systems, or monitoring pipelines\n\nExperience working with human feedback, expert feedback, synthetic data, or policy-grounded training data\n\nExperience in safety-critical or abuse-sensitive domains where models must balance helpfulness, refusal, uncertainty, and user intent\n\nAbout OpenAI\nOpenAI is an AI research and deployment company dedicated to ensuring that general-purpose artificial intelligence benefits all of humanity. We push the boundaries of the capabilities of AI systems and seek to safely deploy them to the world through our products. AI is an extremely powerful tool that must be created with safety and human needs at its core, and to achieve our mission, we must encompass and value the many different perspectives, voices, and experiences that form the full spectrum of humanity.\nWe are an equal opportunity employer, and we do not discriminate on the basis of race, religion, color, national origin, sex, sexual orientation, age, veteran status, disability, genetic information, or other applicable legally protected characteristic.\nFor additional information, please see OpenAI’s Affirmative Action and Equal Employment Opportunity Policy Statement.\nBackground checks for applicants will be administered in accordance with applicable law, and qualified applicants with arrest or conviction records will be considered for employment consistent with those laws, including the San Francisco Fair Chance Ordinance, the Los Angeles County Fair Chance Ordinance for Employers, and the California Fair Chance Act, for US-based candidates. For unincorporated Los Angeles County workers: we reasonably believe that criminal history may have a direct, adverse and negative relationship with the following job duties, potentially resulting in the withdrawal of a conditional offer of employment: protect computer hardware entrusted to you from theft, loss or damage; return all computer hardware in your possession (including the data contained therein) upon termination of employment or end of assignment; and maintain the confidentiality of proprietary, confidential, and non-public information. In addition, job duties require access to secure and protected information technology systems and related data security obligations.\nTo notify OpenAI that you believe this job posting is non-compliant, please submit a report through this form. No response will be provided to inquiries unrelated to job posting compliance.\nWe are committed to providing reasonable accommodations to applicants with disabilities, and requests can be made via this link.\nOpenAI Global Applicant Privacy Policy\nAt OpenAI, we believe artificial intelligence has the potential to help people solve immense global challenges, and we want the upside of AI to be widely shared.
