About the Team
The ChatGPT RLHF team is a specialized subteam within the Post-Training organization, focused on aligning ChatGPT models with user needs through Reinforcement Learning with Human Feedback (RLHF) and related approaches. Our mission is to make ChatGPT more helpful and personalized for users, creating a better experience by learning from large-scale feedback. The team develops the science of reward modeling, scales feedback-driven training, and ensures our models deliver both correctness and nuanced, human-preferred behavior.
We collaborate closely with research, product, and applied teams to deliver measurable improvements in model quality and user experience. Our work directly impacts millions of users globally and contributes to OpenAI's mission of broadly distributing safe AI.
About the Role
As a Research Engineer or Scientist on the ChatGPT RLHF team, you will contribute to the development of advanced reward models and RL techniques to align ChatGPT models with user preferences. This is a dynamic role combining cutting-edge research with engineering, requiring a passion for building impactful, user-focused AI systems.
Location
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:
Advance research on reinforcement learning and reward modeling to enhance ChatGPT's alignment with diverse user preferences.
Build robust offline evaluations and metrics to predict the impact on the product.
Collaborate with cross-functional teams to deploy models in production and iterate quickly based on real-world feedback.
You might thrive in this role if you:
Bring 2+ years of experience in reinforcement learning, RLHF, or large-scale machine learning systems, with experience in user-facing applications.
Hold a Ph.D. or equivalent research experience in machine learning, computer science, or a related field, demonstrating a strong ability to drive impactful research.
Possess hands-on experience with RLHF, recommender systems, or feedback-driven model training, and a deep understanding of how to integrate these into real-world systems.
Why this role?
The ChatGPT RLHF team operates at the intersection of research and product, shaping the future of AI-powered interactions. You'll have the opportunity to work on impactful, user-facing problems while tackling some of the most exciting challenges in AI alignment and model optimization.
