Endex builds AI agents that handle complex, end-to-end work for the world's most demanding teams. Today we're deployed across leading financial institutions and Fortune 500 companies, embedded in the tools and workflows they rely on.

Design System: Build and maintain our design system from scratch.

Visual Identity: Shape Endex's brand through our product, marketing site, and collateral. Create a visual language that feels sophisticated, trustworthy, and cutting-edge

Cross-Functional Collaboration: Work closely with Engineering and Product to ship designs. Balance user needs with technical constraints, especially within Excel's add-in environment

Growth & Conversion: Design signup flows, pricing pages, and upgrade prompts that drive conversion
