AI/ML Engineer at $10M Seed consumer AI dating startup

Are you tired of building internal tools or ad-tech? Join a $10M seed-stage consumer AI startup backed by Forerunner and NFX that is completely redesigning modern dating. As an early AI/ML Engineer, you will own the core matching engine for a voice-first platform where users spend 27 minutes per day interacting with the AI. We are looking for engineers who helped scale recommendation systems at companies like Instagram or Tinder and want to do it again from the ground up. This is a rare chance to work on a product where your models are the entire user experience, offering a $250k-$400k base plus significant equity in San Francisco.

Overview

Role overview

You will own the matchmaking and recommendation systems for a voice-first AI dating app where 80% of introductions lead to real-world dates. As an early engineer, you'll transition these core algorithms from zero to production scale, working alongside a founding team with deep experience from Uber, Cash App, and Faire.
