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.
