UX Design Engineer (US Remote)

Own the Oomnitza design system end-to-end, managing visual language, interaction patterns, accessibility guardrails, and rules that ensure product consistency. Maintain and extend the Storybook component library with correct, documented, performant, and accessible components for Product Engineers. Build and maintain prototyping tooling including design tokens, AI-prompt scaffolds, and design markdowns to accelerate idea-to-prototype workflows. Consult with Product Engineers on out-of-pattern interactions to produce new patterns, components, or guidance. Partner with engineering to align the design system and implementation library, identifying opportunities to promote one-offs into the system. Hold the quality bar for design output by reviewing prototypes against the system and flagging drift. Track the design-engineering space, including Figma plugins and AI design tooling, to propose investments that improve team velocity.
