Job description

Company Overview:

We're Zocks, a venture capital-backed AI startup changing the world of financial services, and other industries that value security and privacy. Our founding team built their careers working on real-time communication products, building enterprise platforms, and crafting tools for some of the most security-conscious industries. With experience gained from industry leaders like Twilio, IBM, Microsoft, and Hearsay Systems, we're using AI to bridge human conversations with enterprise systems, starting with financial services.

Our focus, although simple, is powerful: reinventing business operations and transforming the areas that often get bogged down by slow, inefficient processes. Our innovative platform allows people to communicate naturally, while we capture the information they need, so they can avoid data entry, streamline their operations, and spend more time on what matters most: their clients.
