About the Team

The post-training team is responsible for training and improving the pre-trained models to be deployed into ChatGPT, the API, and to other internal research teams. Within post-training, the retrieval team develops retrieval technology to power ChatGPT and new product experiences built on OpenAI’s reasoning models.

About the Role

As a Research Engineer / Scientist, you will research and develop improvements to our models. Our team works in research areas combining LLMs, retrieval, reinforcement learning, and deep learning. This is not just a RAG implementation role. Our team’s goal is to rethink the way information retrieval can work for agentic AI systems from first principles.

We’re looking for individuals with strong ML engineering skills and research experience, especially with novel and highly capable models, specifically for our retrieval team.

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:

• Own and pursue a research agenda to improve model capability and performance.

• Collaborate closely with the other research and product teams, allowing customers to optimize their own models.

• Build robust evaluations for tracking modeling improvements.

• Design, implement, test, and debug code across our research stack.

You might thrive in this role if you:

• Have a deep understanding of machine learning and machine learning applications.

• Have expertise in retrieval systems or research

• Have 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.
