About the RoleJoin the core team of an early-stage consumer social startup redefining how young people make friends in real life. The company runs AI-powered small group hangouts every week, matching people into compatible groups and handling everything end-to-end - onboarding, profiling, matching, logistics, reminders, and follow-ups - through a suite of AI agents. Thousands of users connect every month, and the platform is rapidly expanding across university campuses across the US.
As a Founding AI Engineer, you will be one of the earliest technical hires, shaping the architecture and direction of the AI systems that power the entire product.

Communication Workflows & AI Agent Orchestration- Design and build agent experiences across channels where users already are (Instagram, iMessage, WhatsApp, TikTok)
- Orchestrate a multi-agent system handling the full user lifecycle from onboarding to follow-up
- Integrate third-party APIs and messaging services into reliable, scalable workflows
- Contribute to human-AI interaction design to make agent experiences feel natural and effortless
What We're Looking For- Required: Hands-on experience building AI/ML systems in production (0-4+ years), ideally in recommender systems, matching, or social graph domains

- Proficiency in collaborative filtering, graph embeddings, and ranking systems
- Experience with reinforcement learning applied to real-world personalization
- Familiarity with multi-channel messaging APIs and AI agent frameworks
- Ability to design scalable infrastructure supporting complex AI workloads
- Strong cross-functional communication skills; comfortable working alongside product, design, and data science
