Letta is building self-improving artificial intelligence, creating agents that continually learn from experience and adapt over time. Founded by the creators of MemGPT, our agents already power production systems and learn daily. We are assembling a world-class team of researchers and engineers to solve AI's hardest problem: making machines that can reason, remember, and learn like humans. This role will pioneer post-training techniques to improve LLM integration into agentic systems, advancing the field through open publishing and code.
