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.

About Factorial 🚀
Factorial is the AI for Business that knows companies, connects how work happens across the business, and turns that context into action.
Founded in Barcelona in 2016, we now have +1,700 employees serving more than 16,000 companies across 112 countries.
Factorial started with a simple idea: companies were spending too much time managing processes and not enough time doing the work they were hired to do:
their best work.
But as companies grow, work gets more disconnected. More people, more tools, more information, and more time spent connecting the dots. Generic AI can answer questions, but it doesn’t know your company. Every time, you have to give it the context.
Factorial is different. Because it’s inside the company, it already knows how it works, including its people, processes, policies, and data. So you can ask it to do real work, from screening candidates and managing expenses to answering questions and creating reports.
AI isn’t the goal. Giving people back their time is.
When work changes, so do we.
We believe in diverse talent:
we welcome applicants from all backgrounds and strongly encourage people of diverse experiences and identities to apply.
We believe in inclusion:
we are committed to equal opportunities and actively promote workplace inclusion of people with disabilities. If you would like to learn more about our inclusive recruitment processes, you are welcome to indicate so optionally and we will share additional information with you.
Our Values
We own it
: We take responsibility for every project. We make decisions, not excuses.
We learn and teach
: We're dedicated to learning something new every day and, above all, share it.
We partner
: Every decision is a team decision. We trust each other.
We grow fast
: We act fast. We think that the worst mistake is not learning from them.
