    About the role#

    We are looking for a Research Intern to join our Agent RL Training team. You will be paired with a full-time mentor to explore how to apply large language models to core business areas, including content understanding, recommendation, agentic web browsing, and autonomous multi-step task completion. This is a hands-on role where you will independently drive experiments, propose novel ideas, and iterate quickly.

    What you'll do#

    • Collaborate with your mentor to identify high-impact research directions for applying LLMs to products.
    • Independently run end-to-end SFT experiments on LLM-based agents and assist with RL-related exploration, such as reward design and training iteration.
    • Curate and build high-quality training datasets, including instruction-following, preference pairs, agent trajectories, and synthetic data.
    • Contribute to public publications, with support for top-venue submissions during your internship.

    What you'll need#

    • Strong Python and PyTorch skills.
    • Independent capability in end-to-end model SFT, with a basic understanding of RL-based post-training methods such as RLHF, DPO, PPO, or GRPO.
    • Excellent taste in model behavior, with the ability to reason about quality across user-facing domains.
    • Genuine passion for research, demonstrated by reading papers and tinkering with models.
    • High motivation and commitment, including the willingness to put in extra hours to push projects to completion.
    • Pursuing a degree in Computer Science, Data Science, or Mathematics.
    • Preferred: Publication at a top-tier venue, experience with multi-node distributed training, proficiency in writing custom GPU kernels with Triton or CUDA, experience building synthetic data pipelines, and familiarity with open-source RL frameworks.

    Location & details#

    • Location: On-site in Mountain View, California.
    • Type: Full-time internship.
    • Compensation: $35 - $50 per hour.
    • Sponsorship: Not provided.
