- Contribute to public publications, with support for top-venue submissions.
What you'll need#
- Strong Python and PyTorch skills.
- Independent capability in end-to-end model SFT and a basic understanding of RL-based post-training methods like RLHF, DPO, PPO, or GRPO.
- Excellent taste in model behavior, with the ability to reason about and articulate what good looks like across user-facing domains.
- A genuine interest in research, such as reading papers for fun or tinkering with models.
- High motivation and commitment to push projects across the finish line.
- Pursuing a degree in Computer Science, Data Science, or Mathematics.
- Preferred: Publications at top-tier venues, experience with multi-node distributed training, proficiency in writing custom GPU kernels, experience building synthetic data pipelines, or familiarity with open-source RL frameworks.
