Founding Engineer at Y/n

Hi, my name is Gabriel and I'm the founder of Y/n. Y/n is an app where you can create, share, and play interactive stories. Today, 100K+ teenagers spend 3+ hours a day in the app playing characters in text stories of their own making. A few facts about why you should join Y/n: We launched 8 months ago and are already one of the top books apps in the world (reached #4 app in the App Store this month). We serve ~2T tokens (~200M user messages, growing 40% MoM) per month with a team of 3. We raised $14M from top VCs. My co-founder Eric is a technical genius. He trained the first-ever image editing AI in the world. Before Y/n, I was the founding designer at Substack. We're looking for a founding full-stack engineer to own most of the app surface and our personalized recommendations infrastructure. This is a role with a lot of ownership across the product! What we expect from you: You’ve built actual infrastructure (not just pushed to Vercel). You’ve worked at a startup or built meaningful side projects. You’re into fandom, reading, and fanfiction! You're based in (or willing to relocate to) San Francisco. Hollywood authored the dominant stories of the last century. Our mission at Y/n i
