Descripción del empleo

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
  
  

If that sounds like you, keep reading.

🧩 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
  
  

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.

🧠 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
  
  

Bonus points if you’ve worked with:

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
  
  

Bonus if:

• 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
  
  

👉 We care far more about what you’ve built than the stack you used.
