Head of Design System

You will own Oxygen, Doctolib's design system—much more than a component library. Oxygen is how we deliver our brand identity consistently throughout the product and the critical infrastructure that ensures design quality at scale across an AI-first development environment. With over 50 designers and engineers building across multiple markets and product surfaces, your work will directly shape the experience of more than 90 million patients and 400,000 healthcare professionals.

What you'll do

• Set the multi-year vision and roadmap for Oxygen, connecting the dots across engineering, design, and brand teams. Translate system health into business impact and own the investment strategy for the teams, tools, and governance that support it.
• Establish cross-functional governance across Design, Product, Engineering, and Brand teams, defining contribution models, change management processes, and the standards other teams are expected to follow.
• Own design output quality across the product, ensuring that AI-generated interfaces are coherent, consistent, and on-brand at every touchpoint across the company.
• Define and drive cross-organizational adoption, measuring adoption rate, component coverage, and contribution velocity, and connecting those metrics to product team speed and quality.
• Manage and grow a team of design system designers and engineers, setting career paths, a high bar for craft, and hiring for the roles the system needs next.

What you'll need

• 10+ years of experience in product design or design systems, with a proven track record of scaling a mature, complex system across multiple product teams or lines of business
• Engineering fluency: you understand the technical architecture of a design system, how platform teams operate, and the latest best practices in AI-first software engineering as it relates to design systems
• Senior stakeholder management skills, with the ability to negotiate priorities with leadership at Director level and above across large, distributed organizations, and drive change management at scale
• Data-informed and outcome-oriented approach: you measure system health in real metrics (adoption rate, handoff defect rate, contribution velocity) and connect those numbers to product quality and business outcomes
• Experience in a regulated, enterprise, or healthcare-adjacent context where accessibility (WCAG), localization (i18n, RTL), and multi-market constraints are critical to design systems
• Fluent in English
