** About the job
***** We're Building Something Extraordinary
*** Imagine an AI that remembers every conversation, every idea, every moment that shaped your thinking. Not to replace your mind, but to amplify it. To help you connect dots you never saw before and whisper the perfect insight just when you need it most.

We're Twin Mind, and we're creating the world's first AI  second brain —one that captures everything you see and hear, building a perfect digital memory that makes you superhuman at being you.

Our founding team has shipped moonshots at Google X, generated $1B+ revenue on Wall Street, contributed to Nobel Prize-winning discoveries, and grown startups to millions of users. We're backed by Silicon Valley's top VCs—the same visionary investors behind Facebook, Robinhood, and Zapier.##
