Research Engineer, Post-Training Evals

About the TeamThe Post-Training team is responsible for training and improving pre-trained models to be deployed into ChatGPT, the API, and future products. The team partners closely with research and product teams across the company, and conducts research as a final step to prepare for real world deployment to millions of users, ensuring that our models are safe, efficient, and reliable.About the RoleWe are seeking a Research Engineer/Scientist to help us deeply understand and improve the capabilities of our models through rigorous evaluation, analysis, and experimentation. In this role, you will lead efforts to correlate evaluation metrics with model behavior, user experience, and real-world performance. Your work will directly inform model development, guide research priorities, and ensure that our evaluation methodologies accurately capture the nuanced capabilities.You will collaborate closely with researchers, data scientists, and engineers to develop robust experimental methodologies, create high-quality evaluation datasets, and design new metrics that capture nuanced aspects of model quality. Your work will bridge the gap between raw metrics and meaningful insights, helping us understand the broader capabilities and limitations of our models.This role is based in San Francisco, CA. We use a hybrid work model of 3 days in the office per week and offer relocation assistance to new employees.In this role, you will:Investigate the relationship between evaluation metrics and model behavior: Design and execute studies to understand how various metrics correlate with user satisfaction, task success, and broader model capabilities.Develop novel evaluation methodologies: Create experimental frameworks and evaluation methods to measure complex model attributes, including alignment, robustness, and generalization.Collaborate cross-functionally: Work with data scientists to analyze user interactions, partner with research teams to implement evaluations and inform model development.You might thrive in this role if you:Have a deep understanding of RL or LLMsHave a working knowledge of relevant models, and building evaluations for model capability improvement.Are comfortable diving into a large ML codebase to debug.Thrive in a dynamic and technically complex environment.Are excited to explore the capabilities and limitations of cutting-edge AI models.About OpenAIOpenAI is an AI research and deployment company dedicated to ensuring that general-purpose artificial intelligence benefits all of humanity.
