Job Description

Researcher, Training Careers at OpenAI - San Francisco, California | Apply Now!

Role Overview

Join OpenAI's elite Training team as a Researcher, Training in San Francisco, California, and become a key architect behind the world's most advanced large language models (LLMs). This senior-level role places you at the forefront of AI innovation, where you'll design, prototype, and scale groundbreaking architectures that power flagship models like GPT-4o, o1-mini, and future AGI systems. OpenAI's Training team is the powerhouse producing LLMs that drive research, products, and humanity's progress toward artificial general intelligence (AGI).

In this high-impact position, you'll combine deep research into architectures, datasets, and optimization with bold long-term bets on model efficiency and capabilities. Expect to integrate cutting-edge techniques into production model artifacts used company-wide. Ideal for researchers with hands-on experience in LLM development, this hybrid role (3 days/week in-office) offers relocation support and the chance to work alongside the brightest minds in AI.

The role demands a sophisticated grasp of model inference, empirical rigor, and versatility—from creative breakthroughs to baseline strengthening, eval design, regression debugging, and bottleneck hunting. If you're passionate about safely deploying world-class LLMs, this is your opportunity to shape the future of AI at OpenAI.

Key Responsibilities

As a Researcher, Training at OpenAI, your contributions will directly elevate model intelligence, efficiency, and new capabilities. Here's what you'll tackle daily:

  • Design Novel Architectures: Innovate new model architectures to boost intelligence, drawing from state-of-the-art transformer modifications.
  • Prototype and Scale: Rapidly prototype ideas and scale them to massive training runs for production deployment.
  • Execute Experiments: Run autonomous and collaborative experiments, analyzing results to drive iterative improvements.
  • Performance Debugging: Deep-dive into model performance issues, resolving regressions and enhancing capabilities.
  • Computational Optimization: Optimize training and inference for peak efficiency on massive compute clusters.
  • Infrastructure Contributions: Build and refine training/inference infrastructure to support frontier model development.
  • Eval Framework Development: Create robust evaluation suites to benchmark architecture improvements objectively.
  • Bottleneck Analysis: Systematically identify and eliminate computational bottlenecks in large-scale runs.
  • Cross-Team Integration: Collaborate with research, product, and safety teams to deploy models safely.
  • Long-Term Research: Pursue ambitious bets on next-generation architectures for AGI-scale systems.
  • Model Artifact Production: Deliver world-class models like GPT-4-Turbo that power OpenAI products.
  • Empirical Research: Apply hands-on, data-driven methods to validate and iterate on architectural hypotheses.
  • Safety-Focused Deployment: Ensure architectures support safe, real-world LLM applications.
  • State-of-the-Art Tracking: Stay ahead of transformer efficiency trends and integrate them rapidly.

These responsibilities position you as a pivotal player in OpenAI's mission to benefit humanity through safe AGI.

Qualifications

To excel as a Researcher, Training, you'll need proven expertise in LLM research. Top candidates demonstrate:

  • Deep expertise in LLM architectures, including transformers and modifications for efficiency.
