Our Product Design team works across multiple product lines, from web and SaaS to Android and POS hardware, as we move toward a shared foundation. We are looking for a Design System Lead to lead the next evolution of that foundation. You will own the design system end-to-end, from token architecture and component governance to AI-assisted tooling that closes the gap between Figma and production.

You will define what should be standardized across platforms and what should remain platform-specific, creating a cohesive product experience without forcing a single technical implementation. This is a high-impact, high-autonomy role at the intersection of systems design, front‑end engineering, and modern AI workflows. This role is onsite and can be based at any of the following Shift4 locations:
Tampa, FL (preferred) / Atlanta, GA / Center Valley, PA Relocation assistance may be available.

• Assess the current state of our design systems across design and engineering, identify gaps and duplication, and establish a practical roadmap for unification, migration, and ongoing governance.
• Own, evolve, and consolidate our design system foundations across web, mobile, and POS products.
• Define and maintain scalable token architecture, component libraries, theming, accessibility standards, and cross-platform patterns.
• Lead the migration of existing and legacy interfaces to the shared design system, using AI‑assisted tools and workflows to accelerate the process at scale.
• Drive design‑to‑code alignment between Figma and production, establishing practical workflows that connect design, design system code, and production.
• Partner closely with engineers to translate design system foundations into production, accelerate component migration, identify inconsistencies, and improve adoption across products.
• Identify and implement AI‑assisted opportunities to automate repetitive design system work, including audits, component mapping, documentation, and migration.
• Establish clear design system standards and review mechanisms that prevent teams from creating redundant or non‑compliant components and ensure new work aligns with the shared system.
• Work closely with Product and Engineering leads to ensure the design system accelerates product development rather than creating additional processes or rework.
• Mentor designers on implementation‑aware design, token usage, systems thinking, and AI‑enabled workflows.
• Create practical documentation, examples, and guidelines that help product teams correctly adopt and extend the design system.

• 7+ years in Product Design, Design Systems, or UX Engineering roles.
• Proven track record building, evolving, and implementing production‑ready design systems at scale.
• Deep expertise in token architecture, theming, component variants, accessibility, and cross‑platform design systems.
• Strong Figma skills and understanding of design system best practices, governance, and design‑to‑code workflows.
• Hands‑on experience with React, ShadCN, and Tailwind CSS, as well as Kotlin/Jetpack Compose and Material 3, with a strong understanding of how design system components, tokens, and patterns are implemented in production code.
• Demonstrated ability to use AI‑assisted tools to accelerate design system work, including migration, auditing, component generation or mapping, documentation, and design‑to‑code workflows.
• Strong understanding of front‑end implementation and the ability to collaborate directly with engineers on production design system components.
• Clear communicator who can align design and engineering around shared conventions and technical constraints.

• Experience in fintech, commerce, POS, or SaaS product environments.
• Experience migrating legacy design systems or products to a new unified system.
• Experience using AI to…
