Responsibilities

: leading the refactor and governance of our Design System, and—once the foundations are set—contributing as an embedded Product Designer within a squad. Phase 1 (~6 months): Fully dedicated to the Design System—building robust, scalable foundations, defining governance, and aligning the system with product and engineering needs. Phase 2 (ongoing): Embedded in a product squad, contributing to delivery and discovery, while maintaining stewardship of the Design System.

As Design System Lead You will transform Onebox's Design System into a scalable, enforceable product infrastructure that reduces rework, protects brand and UX consistency, and accelerates delivery across teams and devices (web, mobile, and digital kiosks). What you'll own: Audit and refactor existing components, tokens, and patterns into a coherent, scalable architecture (tokens, spacing, typography, color, motion). Build a multi-brand theming system that supports current and future brands.

Define and implement the governance model: decision rights, intake process, contribution workflows, versioning, and release cadence. Partner with a dedicated DS Engineering team to ensure Figma–code parity and eliminate one-off UI implementations. Structure system primitives for AI-assisted prototyping, keeping AI-generated concepts system-compliant.

Drive adoption across squads through documentation, training, and health metrics.

What We'Re Looking For

: Proven experience refactoring and scaling a Design System in production. Strong systems thinking and UI craft, with experience defining governance and enforcing standards. Experience with scalable token architecture and automated distribution pipelines.

Solid understanding of HTML/CSS/JS; cross-browser knowledge and semantic HTML best practices are a strong plus. Multi-brand theming and AI workflow integration experience are a bonus. Portfolio demonstrating real production impact on a Design System (required).

As Product Designer Embedded in a squad alongside engineers, a PM, and researchers, you'll take full ownership of key product areas—from early concepts to high-fidelity delivery—on both mobile and web. What you'll own: Lead design projects end-to-end, from discovery to final specs, with a focus on activation, retention, and engagement. Rapidly produce concepts and prototypes, balancing exploration with execution.

Translate user insights, technical constraints, and business needs into well-crafted, data-informed solutions. Collaborate closely with engineers, PMs, and researchers, incorporating their perspectives into your work.

: Proven experience as a product designer at a consumer-focused tech company. Strong UX and visual design skills, with a sharp eye for mobile and responsive web experiences.
