Design System Architect: This is for a systems thinker with technical firepower , a builder’s mindset , and a strong design eye . You’ll own the architecture of our company-wide design system — evolving it from a set of components to a real product infrastructure that fuels consistency, quality, and speed across every team.

Think: building the rails for AI-powered design → dev workflows, creating seamless tooling from Figma to code, and setting the bar for how we scale quality across the product. Factorial is scaling fast — and this role is about laying the foundations for design and engineering to move at 10x speed with 10x consistency . You’ll have massive ownership, shape how we build product across the org, and leave a legacy in how we approach design quality at scale.

You’ll be engineering the product underneath the product. As a Design System Engineer at Factorial, you’ll help define and build the next generation of our AI-native product using modern AI development practices .
