Founders Associate at Mozart AI

Are you a high-agency operator looking to build the future of music? This isn't a GTM role—it's a high-velocity operational and technical apprenticeship. You'll build AI agents, own critical operations, and drive strategic initiatives for a platform already serving 250k+ users. If you are a low-ego, technical generalist who wants to learn how to build a company from the ground up, this is your next move.
