Factorial is scaling fast and this role is about laying the foundations for design and engineering to move at 10x speed with 10x consistency. Youll have massive ownership shape how we build product across the org and leave a legacy in how we approach design quality at scale.

You wont just be contributing to a system.

• Proven impact: shipped projects side projects or contributions that made a measurable difference
• Product-first thinking: you design complete experiences not just isolated components
• Speed & adaptability: you experiment learn and iterate fast

Bonus points if youve worked with:

Technical Foundation (Not Strict Requirements)

Strong candidates often have:

• Deep experience with React TypeScript and the modern frontend ecosystem
• Strong understanding of Figma tokens and component libraries
• Experience translating early concepts into production-grade design systems

Bonus if:

• Youve built or contributed to internal tooling plugins or Figma-to-code pipelines
• Youve explored ways to use AI to automate or accelerate parts of the design dev flow
