Product Engineer

Product Engineer Ciridae San Francisco, CA Job Details Full-time 23 hours ago Qualifications AI Generative AI Full Job Description You build the applications customers actually use. Full-stack, at a pace that isn't normal. You're equally good debugging an agent loop at 2am and demoing the feature to an ops lead the next morning. What you own. AI-native applications end-to-end - React + TypeScript on top, Python + FastAPI + Postgres underneath, LLM orchestration in the middle. Prototype production iteration. Evals, observability, and the unsexy plumbing that keeps the whole thing running. Direct customer contact when it's the fastest way to build the right thing. What you bring. Production experience across React/TypeScript, Python, and at least one LLM API in a real application. Strong opinions about RAG, agents, and evals, formed by shipping. You translate between a stakeholder's problem and the system that solves it without needing a PM in the middle. Level. Experienced engineers own feature areas end-to-end. Early-career ramps fast on live customer systems.
