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,
