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.

About the Quartz App team

As a member of the Quartz App team, your mission is to ensure that the design system works just as well in applications as it does on the web, translating shared foundations into app-ready components, patterns, and guidelines.

You work closely with Quartz Core to reuse and influence the foundations, and with product app teams to capture real constraints, validate solutions, and drive adoption.

The team operates as a product team: clear outcomes, a roadmap aligned with platform OKRs, and tight collaboration with design, engineering, accessibility, and brand stakeholders.

What will be your role ?

As the Lead Developer for the Design System Application Team, you will be responsible for implementing and maintaining application-specific patterns and components while ensuring technical feasibility, performance, and alignment with the Core Design System.
