Lead Developer | Design System Software & Applications

About Quartz Design System Quartz is Schneider Electric’s design system, built to guarantee consistency, quality, and scalability across hundreds of digital products while accelerating product teams’ delivery. The design system is organised into complementary teams: Quartz Core defines and maintains the foundations (tokens, components, governance, tooling), Quartz Website focuses on web-specific implementation and adoption at scale, and Quartz App adapts and extends the system for mobile and software applications. Context As the platform matures, the Quartz App team is growing to take on more ambitious challenges beyond Core components. The next phase focuses on domain-aware patterns and end-to-end flows tailored to technical software used in energy management and industrial automation, where density, criticality, and expert users are key constraints. This means developing and systemising advanced interactions such as monitoring dashboards, configuration flows, alarms, controls, and decision-support experiences.
