You will own the core matchmaking, recommendation, and ranking systems from zero to production scale. As an early engineer, you will shape the algorithm that defines how users find connection, moving beyond swiping to a high-intent, single-match experience. You'll work directly with founders from Uber and Cash App in San Francisco.
AI/ML Engineer at Known — VC-backed AI Dating Startup
Known is reinventing connection with a voice-first AI matchmaker that skips the swipe for high-intent, single matches. Backed by a $10M seed round from Forerunner and NFX, they are looking for an AI/ML Engineer to own the core matchmaking engine. If you've built and scaled recommendation systems at companies like Tinder, Spotify, or Instagram during their early growth windows, this is your chance to lead a production system from zero to scale. Based in San Francisco's Cow Hollow, you'll work with a founding team from Uber and Cash App to define the future of dating.
