Tech description:

Job description:

Hi, my name is Gabriel and I'm the co-founder of [Y/n](https://apps.apple.com/us/app/y-n/id6744907251). Y/n is an app where you play the main character in a story written for you. Be the new kid at a boarding school and get everyone to fall for you, or plan a jailbreak with Sherlock Holmes. Every text you send changes the plot and how characters feel about you, so no two playthroughs are the same. Our mission at Y/n is to create the most entertaining storyteller in the world, and give it to everyone. ### Why you should join us * People love Y/n: * Users spend on average 3+ hours playing Y/n everyday * We are top #10 books apps in the world (reached #4 app in the App Store last month), even though we just launched * We raised $14M from top VCs * We work on interesting technical problems: * We serve \~3T tokens (\~300M user messages, growing 40% MoM) per month with a team of 4 * We manage a LOT of compute! * Training an AI to be fun and creative is incredibly interesting * The founders + team are fun to work with: * My co-founder Eric trained the first-ever image editing AI in the world * Before Y/n, I was the founding designer and one of the first employees at Substack, where I learned a lot about product and media * Together, we previously co-founded Can of Soup, a hit AI image sharing app, which you can read about in the [New York Times](https://www.nytimes.com/2023/09/27/technology/ai-images-social-media-sharing.html) ### Some examples of what you would do You'd be one of our first engineers, with real ownership across the product and the infrastructure. In practice that could mean: * Building our personalized recommendation system infrastructure * Building features in our mobile and web application The role will adapt and grow as we do, so don’t worry if you haven’t worked on recommender systems or ML yet! ### What we’re looking for * You’ve built actual infrastructure (not just pushed to Vercel) * You’ve worked at a startup or built meaningful side projects * Optional: you’re into fandom, reading, games, or fanfiction! * You're willing to relocate to San Francisco. If you do not have US work authorization, we can help with that
