z0.ai Full Time Founding Engineer On Site 5 days a week NYC 140- 180k USD equity
Founding Engineer role at z0.ai, responsible for owning the full stack end-to-end, including product surfaces, services, and ensuring a seamless user experience while meeting security and compliance requirements.
z0.ai | Full Time | Founding Engineer | On Site 5 days a week | NYC | $140-$180k USD + equity We're helping non technical users adopt AI by making usage visible. Power users become role models and people can upskill to gain value rather than lose their jobs to AI. It's a complex problem because we need to balance trivial UX, with a slew of security and compliance requirements. This is the first non founder developer role on the z0.ai codebase. We need someone who can own the full stack end to end: product surfaces people enjoy using, services that stay correct, and the taste to make both feel like one product. We're funded and are live with our first customer already. We expect to onboard our next customer later this week and are actively ramping up sales efforts.
