-- 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
