Join a founding team in San Francisco building an AI-first platform that organizes real-world social connections for young people, with curated small-group hangouts powered end-to-end by AI agents. As a Founding AI Engineer, you'll own AI-driven matching and social-graph components, and multi-channel AI agent experiences. This is a ground-floor opportunity with significant equity upside to help solve loneliness among Gen Z at growing scale across US university campuses. No visa sponsorship is available; candidates must be eligible to work in the United States without employer sponsorship.

What You'll Do - AI Matching & Social Graphs: Design and build a novel social graph derived from real-world interaction data; process millions of data points; develop collaborative filtering, graph embeddings, and ranking systems; apply reinforcement learning from real-world outcomes to improve personalization; discover patterns that correlate with meaningful friendships. - Multi-Channel AI Agent Experiences: Architect and build agent workflows that operate across messaging platforms (Instagram, iMessage, WhatsApp, TikTok, and others); integrate and orchestrate multiple AI agents, third-party APIs, and the data layer into a seamless user experience; design scalable production-grade infrastructure to support AI workloads and multi-channel agent orchestration; craft human-AI interactions that feel natural, reliable, and effortless at scale.
