Design System Engineer

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.

You will:

• Lead and scale our design system across the company Define the technical architecture, tooling, documentation, governance, and implementation plan. Help us rethink how design systems operate in an AI-native product development flow

• Design and implement AI Skills Build tools and plugins that connect Figma * code * AI-driven workflows

• Develop and maintain evaluation frameworks (Evals) Partner with design, frontend, and product to ensure pixel-perfect execution at scale. Drive best practices around accessibility, responsiveness, and usability

• Stay close to our customers We have a strong customer-centric mindset: engineers regularly join customer calls, reviews, and feedback sessions to deeply understand real workflows, pain points, and constraints - ensuring we build the right solutions to real problems, not assumptions.

• Share knowledge and raise the bar Mentor peers, document learnings, and contribute to Factorial's AI engineering best practices.

Your title matters less than your mindset.

You might be mid, senior, or staff, what we care about is:

• AI as a habit: you've built real AI-powered systems or workflows (not just experiments)
• 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

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., LLMs, skill-based agents, MCP, or other AI protocols

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
• Product sense - you don't just code components, you understand why they exist
• Builder mindset: you ship fast, clean, and don't wait for perfect specs
