About the role
Solving Self-Improving Superintelligence The human brain is a sponge. Today’s AI brains are brittle and rigid. At Letta, we’re building self-improving artificial intelligence: creating agents that continually learn from experience and adapt over time. Founded by the creators of MemGPT from UC Berkeley’s Sky Computing Lab (the birthplace of Spark and Ray). Backed by Jeff Dean, Clem Delangue, and pioneers across AI infrastructure. Our agents already power production systems at companies like 11x and Bilt Rewards , learning and improving every day. We’re assembling a world-class team of researchers and engineers to solve AI’s hardest problem: making machines that can reason, remember, and learn the way humans do. Note that this role is in-person (no hybrid) , 5 days a week in downtown San Francisco. At Letta, we are re-imagining the developer experience for building, deploying, and interacting with advanced AI agents. We believe the true potential of AI can only be reached if developers are given the tools to deeply understand how their agents are working through open AI systems and innovative product design. We are creating a developer experience that prioritizes: Transparency: We don’t believe in trying to hide the inner workings of agents (unlike closed AI companies) or trying to impose unnecessary abstractions: instead, we focus on providing tools to help developers understand exactly how their agents are interfacing with LLMs (e.g. what exactly is being placed into the LLM context window and why). Control: Developers should have granular control of model backends, memory, cross-agent communication, and tools - but getting starting and integrating end applications should be simple and seamless. Experience: LLMs are an incredible technology, and working with LLMs should be a joyful and exciting experience. We care deeply about building best-in-class products that are beautifully designed. As a product engineer, you will help build, design and define how developers will interface with our agent framework through our application surfaces: Our Agent Development Environment , a visual interface for designing agents and tools, distributed on the web and desktop on MacOS and Windows. Our application SDKs that enable developers to build full-stack agent apps with 5 lines of code. Our Cloud Platform , that enables seamless deployment, monitoring and testing of agents in production with zero infrastructure setup. You will work closely with designers, researchers, and the founders to build the visual interfaces for innovative agent functionality (e.g. multi-agent collaboration, memory, voice, etc.). You will interface closely with customers and Letta’s active open source community to understand their agent use-cases and how the developer experience can be improved. Skills: Strong frontend development skills (React) Experience with fullstack development, including API design, interacting with DBs (Postgres, Redis), and crafting user experiences Proficiency with backend development (Next.js, Node, Typescript,
