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.** ## ‍ 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 ## ℹ️ About us At Factorial, we’re building the leading business management software for companies of all sizes.
