Research Scientist Intern, PhD — Meta Superintelligence Labs

Meta is seeking Research Interns to join our AI Search research team. We are committed to advancing the field of artificial intelligence by making fundamental advances in how AI agents learn from their own experience - improving their search and reasoning workflows, retaining useful knowledge, and transferring those gains to unfamiliar tasks. A central research challenge is making repeated self-improvement reliable when feedback is sparse or noisy.

The intern will work in one of three directions, scoped closer to the start date together with the intern manager:

-Learning to improve research workflows - agents learn better search, tool-use and verification strategies from prior attempts by improving their harness: the workflow, memory, tools and feedback loop around the model. Topics include meta-learning across tasks, automated agent design, and learning from natural-language feedback.

-Persistent memory and continual learning - agents retain useful lessons and update knowledge across tasks, whether in context, in compressed memory, or in weights, without forgetting what they already know. Topics include long-context modeling, context compression, continual learning, and test-time training.

-Learning from imperfect feedback - turning noisy judgments and failed attempts into useful learning signals, and improving the strategy an agent uses to learn, including how it selects and evaluates its next improvement. Topics include reward learning, credit assignment, and learning to learn.

Across all three directions, the key test is whether improvements transfer to new tasks. The goal is to develop novel methods and experiments toward a first-author submission at a leading ML/NLP venue. Recent internships on this team have produced work such as REFRAG, a new architecture for retrieval-augmented generation.

Our internships are twelve (12) to twenty-four (24) weeks long and we have various start dates throughout the year.

Responsibilities

Develop novel state-of-the-art methods for self-improving, agentic AI systems, leveraging a range of deep learning and reinforcement learning techniques. Design and run experiments that test whether agent improvements generalize and transfer to unseen tasks. Perform research to advance the science and technology of intelligent machines. Help analyze and improve the reliability and robustness of the resulting methods. Collaborate with researchers and cross-functional partners, including communicating research plans, progress, and results. Disseminate and publish research results, and contribute to research that can be applied to Meta product development.
