About the Role
A fast-growing, AI-first consumer social platform is hiring a Founding AI Engineer to join its core team in San Francisco. The company uses AI agents to facilitate real-world, in-person social connections — organizing curated small-group hangouts for young people, with a growing presence across university campuses in the US. The platform operates entirely through AI: matching, logistics, reminders, follow-ups, and continuous learning, all without a traditional app.
As a founding engineer, you will own two mission-critical pillars of the product and have an outsized impact on the direction of the technology.
What You'll Do
AI Matching & Social Graphs
-
Build a new type of social graph grounded in real-world interaction data
-
Match people into highly compatible groups and surface patterns that drive meaningful friendships
-
Work with millions of data points using collaborative filtering and graph intelligence
-
Develop and iterate on embeddings, ranking systems, and large-scale personalization
-
Apply reinforcement learning informed by real-world outcomes
Communication Workflows & AI Agent Experience
-
Design and build AI agent experiences across channels where users already are (e.g. Instagram, iMessage, WhatsApp, TikTok)
-
Orchestrate multi-channel agent workflows connecting APIs, third-party services, and the database layer
-
Build scalable infrastructure to support complex, multi-step AI workflows
-
Own human-AI interaction design for a seamless, natural user experience
What We're Looking For
Required:
-
4–10+ years of experience building AI/ML systems in production
-
Comfort working across the full stack — from data pipelines to user-facing agent interactions
-
Familiarity with multi-channel messaging APIs and agent frameworks
-
Founding mindset: you ship fast, own problems end-to-end, and thrive in ambiguity
Nice to Have:
- Experience with recommendation systems, social graphs, or large-scale personalization
Compensation & Benefits
-
Salary: $150,000 – $200,000 USD annually
-
Equity: Meaningful founding-level equity
-
Early-stage opportunity with significant upside in a growing consumer tech company
