Your role

You will design the long-term memory architecture for LLMs. At Letta, you'll work with a world-class, tight-knit team of AI researchers and engineers towards our vision of self-improving superintelligence. Advance the field through open publishing of research through papers, technical reports, blog posts, and open-source code.

What You’re Responsible For:

  • Defining the key abstractions of the LLM memory layer
  • Building memory architectures that support multiple memory types including temporal sequences, episodic experiences, semantic knowledge, and procedural skills
  • Researching memory sharing between multiple agents that enable effective multi-agent collaboration
  • Improving context management techniques that solve the long-context / context derailment problem
  • Running evaluations for measuring and improving memory for agents

What We're Looking For:

  • Deep expertise in LLMs and retrieval
  • Track record of impactful research (breakthrough publications and/or open source contributions)
  • Ability to balance execution speed with empirical rigor
  • Real-world impact beyond pure academic work
