About the role#
This PhD research internship focuses on the intersection of reinforcement learning and large language models. You will join the applied deep learning research team to advance foundation models and develop methods to improve their reasoning, alignment, and reliability. The role emphasizes hands-on experimentation and rapid prototyping at scale.
What you'll do#
- Develop and prototype reinforcement learning algorithms for large language models.
- Explore methods to improve reasoning, instruction following, alignment, and multi-turn interaction.
- Design experiments to evaluate model behavior, task performance, robustness, and hallucination.
- Implement research ideas using Python and PyTorch.
- Run experiments on large-scale GPU clusters.
What you'll need#
- Current pursuit of a PhD in AI, ML, Computer Science, Computer Engineering, Electrical Engineering, Mathematics, or Physics.
- Strong background in reinforcement learning and natural language processing.
- Excellent programming skills with a focus on Python.
- Experience with deep learning frameworks like PyTorch.
- Comfort with experimental research, debugging models, and working with large-scale training pipelines.
- Preference for candidates with publications or open-source contributions in RL, LLMs, alignment, reasoning, or post-training.
- Experience with RLHF, RLAIF, policy optimization, reward modeling, or agentic LLM systems is a plus.
Location & details#
- Location: Santa Clara, California (On-site).
- Term: Fall 2026.
- Employment: Full-time internship.
- Compensation: 38 USD to 94 USD per hour, based on location, education, and experience.
