Senior UX Engineer

When is a US-based, venture-backed company that has built a novel AI-driven health insurance marketplace and post-employment platform. They are seeking a Senior UX Engineer to own and elevate the user experience across their platform, focusing on architecting a robust UI framework and leading the design of AI-embedded product experiences.

Responsibilities:

• Own the end-to-end user experience strategy, establishing and enforcing UX patterns, component libraries, and design tokens that ensure visual and behavioral consistency across the platform
• Architect a robust, extensible UI framework (React/Next.js) purpose-built for embedded AI chat interfaces, contextual assistance panels, and conversational UX flows
• Define and maintain a living design system that bridges design and engineering, reducing duplication and accelerating feature delivery
• Future-proof our front-end architecture so new features, partner integrations, and AI capabilities can be added without rework
• Lead the UX design and implementation of AI chat tools embedded within the application—guiding users through COBRA elections, ACA marketplace enrollment, and benefits decisions
• Collaborate closely with engineers to translate LLM capabilities into intuitive, trustworthy user interfaces
• Design interaction patterns for AI-driven features: streaming responses, confidence indicators, graceful fallbacks, and human-in-the-loop escalation paths
• Prototype and iterate rapidly using AI-assisted development tools (e.g., Claude, Cursor, Figma AI) to accelerate the design-to-code cycle
• Instrument the UI framework with structured event tracking and analytics hooks that feed into our data pipeline for reporting and insights
• Build and manage an A/B testing infrastructure within the front end, enabling the product team to run controlled experiments on UX flows, copy, and AI interaction patterns
• Define and optimize for specific user outcomes—enrollment completion rates, time-to-decision, support deflection—using data to drive iterative UX improvements
• Partner with Product and Data teams to create dashboards and feedback loops that make UX performance visible and actionable
• Serve as the UX authority across engineering squads, providing guidance, code reviews, and hands-on mentorship on front-end best practices
• Work directly with the VP of Product and CTO to translate product strategy into UX roadmap priorities
• Establish UX quality standards and review processes that scale with the team
• Contribute to hiring and onboarding as the engineering team grows
