Hello 👋
Do you want to help us
Hello 👋
Do you want to help us redefine how AI powers the future of Business Management software, not as an add-on, but as a core part of how people work, decide and grow?
We’re looking for engineers who:
- 🧠 Treat AI as central to their craft
- ⚡ Are obsessed with building and shipping fast
- 🎯 Care about real impact, not hierarchy or titles
🧩 The Role
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 won’t just be contributing to a system.
You’ll be engineering the product underneath the product.
🚀 What You’ll Do
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
- Design and implement AI Skills
- Develop and maintain evaluation frameworks (Evals)
- Stay close to our customers
- Share knowledge and raise the bar
🧠 What we’re looking for
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
LLMs, skill-based agents, MCP, or other AI protocols 🤖✨
🧱 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
- 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
- You’ve built or contributed to internal tooling, plugins, or Figma-to-code pipelines
- You’ve explored ways to use AI to automate or accelerate parts of the design → dev flow
- You see design systems as a strategic layer, not just a UI toolkit
🏢 How We Work
- Office-first in Barcelona & Madrid, with 20% remote flexibility
- A people-first, high-trust culture built on radical candor and ownership
- A multicultural team (40+ nationalities) building the next generation of business management software
