Role OverviewWe’re looking for a Senior UI/UX Designer to lead and evolve our design system while crafting high-impact product experiences across our platform. This role blends design systems strategy with hands-on product design execution. You’ll partner closely with product managers, engineers, and fellow designers to bring clarity, polish, and consistency to every user touchpoint.
This is a high-ownership, high-impact opportunity for someone who thrives in early-stage environments, values design craftsmanship, and wants to create elegant experiences that enable enterprises to safely adopt AI.
Key ResponsibilitiesSet the aesthetic direction: Define a cohesive visual language in partnership with marketing and brand that spans all user touchpoints.

Document with clarity: Collaborate with Engineering to publish a single source of truth in Storybook, using AI tooling to scale documentation and usage guidelines.
Simplify complexity: Understand personas, workflows, and pain points—then turn advanced AI security concepts into intuitive, end-to-end product experiences.
Partner with Engineering: Ensure alignment between Figma components and frontend technologies (React, shadcn/ui, Tailwind, Recharts).
Maintain a high bar for quality: Review and sign off on UI implementations to ensure they meet design standards before they ship.
Ensure accessibility compliance: Make sure designs and code meet WCAG standards to support inclusive experiences.
Design for scale: Create layouts that work fluidly across devices—from mobile to large enterprise displays.
