You’ll be a great fit if you: Thrive in an in-person, high-energy environment —we love bouncing ideas in real life. Are a creative builder —you love turning ideas into real, working products. Own your work like a founder —no one needs to chase you down; you take full responsibility and run with it. Love working in a fast-paced team —startups move fast, and you’re here for the ride. Are obsessed with learning —you dive deep into new topics, master them quickly, and apply what you learn. Have built something cool before —a side project, an app, a browser extension, a tool you couldn’t find so you made it yourself—show us what you’ve created.
