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
