Backend & Data Engineer

San Francisco

* **Evolve the foundation:** You will help us transform our data layer into a mature and battle-tested system. You will build pipelines to extract context from third-party tools and normalize it into a queryable organizational knowledge base. * **Build "Agent-Ready" interfaces:** You aren't just building APIs for a frontend; you are building tools for AI agents. You will abstract away the complexities of external platforms into reliable, clean interfaces that our AI agents can control autonomously. * **Orchestrate async workflows:** We use sleep-time compute cycles to analyze data when users aren't looking. You will manage the worker infrastructure that allows agents to plan cycles, execute sub-tasks, and sync data in the background. * **Semantic search \& RAG:** You will ensure that as soon as data flows in, it is vector-embedded and ready for retrieval, keeping our AI's context window fresh. * **Ship for the user:** We don't optimize code just for the sake of code. You will build with a relentless focus on how the end-user experiences the product: speed, reliability, and magic.
