Research Scientist Intern, FAIR – Multi-Agent Systems and Memory (PhD)

Meta is seeking Research Interns to join our Fundamental AI Research (FAIR) Communication & Language teams working on multi-agent systems and memory. These teams are committed to advancing artificial intelligence through fundamental breakthroughs that enable agents to reason, learn from experience, and collaborate on complex tasks. We are looking for individuals passionate about large language models, agentic systems, machine learning, and reinforcement learning. Our interns have the opportunity to make core algorithmic advances and evaluate their ideas at scale. This internship will investigate how AI agents can retain and use knowledge across extended interactions, share information effectively, and adapt their workflows based on experience. Our research connects memory and multi-agent collaboration with self-improving systems for automated scientific research. Potential directions include developing compact memory representations, improving inter-agent communication and coordination, and automatically optimizing agent harnesses. The specific research question will be shaped by the intern's interests and early experimental findings. We are especially interested in candidates with expertise in one or more of the following areas: Multi-agent systems, collaboration, coordination, communication, and shared knowledge Agentic memory, long-term memory, implicit or parametric memory, and memory retrieval and utilization Long-context modeling, context compression and compaction, and KV-cache compression Self-improving agents, adaptive agent workflows, agent harness optimization, and test-time learning and adaptation Reasoning, planning, tool use, reinforcement learning, and automated scientific research Our team at Meta AI offers twelve (12) to twenty-four (24) weeks long internships and we have various start dates throughout the year.

Responsibilities Conduct fundamental research on memory and multi-agent collaboration to improve AI agents on complex, long-running tasks. Brainstorm with research mentors, review relevant literature and existing systems, and formulate focused research questions. Develop novel algorithms and architectures for retaining and retrieving context, sharing knowledge across agents, or adapting agent workflows based on experience. Implement prototypes and conduct rigorous experiments on automated research and related agentic benchmarks, comparing against strong baselines. Analyze agent trajectories and failure modes to assess memory utilization, coordination, task performance, computational cost, and generalization. Draft research reports and/or publications and present research outcomes to internal and/or external audiences. Contribute research that can be applied to Meta product development.
