About the role#
Meta is seeking Research Scientist Interns to join the Meta Superintelligence Labs (MSL) team. This group focuses on agentic post-training for Muse foundation models. The work spans the full post-training cycle, including supervised fine-tuning, reinforcement learning, evaluation, and the creation of agentic tasks and environments. You will work on improving model capabilities like long-horizon task completion, tool use, and deep research. Internships last between 12 and 24 weeks, with various start dates available.
What you'll do#
- Develop new agentic post-training methods and systems using deep learning and reinforcement learning.
- Work across the full LLM post-training stack to execute, analyze, and iterate on large-scale runs.
- Improve the efficiency, scalability, and stability of agentic training algorithms and deployed systems.
- Advance the technology behind intelligent agents that reason, use tools, and finish complex tasks.
- Collaborate with researchers and cross-functional partners to share progress and research plans.
- Share your results through publications, presentations, model contributions, or open-source releases.
- Contribute research that can be applied to Meta product development when applicable.
What you'll need#
- Currently pursuing a Ph.D. in Computer Science, Artificial Intelligence, Machine Learning, Natural Language Processing, or a related technical field.
- Research experience in machine learning, deep learning, or natural language processing.
- Experience with PyTorch and programming languages such as Python, C++, C, or Java.
- Ability to obtain and maintain work authorization in the United States.
- Intent to return to your degree program after the internship.
- A track record of results, such as patents, grants, fellowships, or first-authored publications.
- Experience with LLMs, foundation models, post-training, reasoning, or coding.
- Knowledge of reinforcement learning, reward modeling, and agentic systems like workflows or tool use.
- Experience with LLM evaluation and setting up machine learning experiments.
- Demonstrated engineering experience through internships, work, coding competitions, or open-source contributions.
- Ability to work and communicate effectively in a team environment.
Location & details#
- This position is based in Menlo Park, California.
- The role is on-site.
- Compensation ranges from $7,650 to $12,667 per month.
