Software Engineer (San Francisco)

Building The AI Operating System

We believe AI's future isn't just more intelligent language models, it's agents that remember, learn, and evolve over time. We're building the AI Operating System to turn stateless models into perpetual and self-improving intelligence.

Letta is founded by AI researchers from UC Berkeley's Sky Computing Lab (the same lab that produced Spark ? Databricks and Ray ? Anyscale), and the creators of MemGPT. We're backed by leaders in AI and infra, including Jeff Dean (Chief Scientist at Google AI), Clem Delangue (CEO of HuggingFace), and Cris Velenzuela (CEO of Runway). Our technology is already being deployed in production to create autonomous, self-improving AI agents at companies like 11x and BILT Rewards.

We're looking for incredibly talented individuals to join our team of AI researchers and engineers to create the first AI OS with human-like memory and learning capabilities. Join us and build the future of open AI, in the heart of San Francisco.

Note that this role is in-person (no hybrid), 5 days a week in downtown San Francisco.

We are building the developer stack for agents that can run in production applications, not just demo notebooks. As a Software Engineer, you will bridge the gap between bleeding-edge agent systems and production-grade software for running agents in real applications. You will help define developer APIs for agents, and lead development of our company's OSS stack as well as the hosted service.

Responsibilities :

• Develop Letta's OSS agents framework and cloud service
• Design scalable & resilient backend services and APIs to support Letta Cloud
• Work with researchers and support bleeding-edge agent architectures in Letta
