As a Founding Engineer, you'll work across the stack to build core product experiences and the systems behind them. You'll partner closely with product and design, own projects from idea shipped scaled, and help shape the engineering culture and technical direction as we grow., * Build 0 1 product features end-to-end: discovery, technical design, implementation, launch, and iteration.

 * Use the latest AI tools every day - build with them, push their limits, and learn alongside teammates doing the same.
 * Ship across the stack (web app, backend services, data, infrastructure) with a bias toward simple, durable systems.
