Nice to have
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
LLMs, skill-based agents, MCP, or other AI protocols 🤖✨
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.
High growth, multicultural and friendly environment
Competitive ESOP plan
Alan as private health insurance
Healthy life with Wellhub (Gyms, pools, outdoor classes)
Save expenses with Cobee
Language classes
Breakfast in the office and organic fruit
Food discounts with Nora

Much more that we'll spill during the interview process!
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.
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.
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:
Define the technical architecture, tooling, documentation, governance, and implementation plan. Help us rethink how design systems operate in an AI-native product development flow
Build tools and plugins that connect Figma → code → AI-driven workflows
Partner with design, frontend, and product to ensure pixel-perfect execution at scale. Drive best practices around accessibility, responsiveness, and usability
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.
Mentor peers, document learnings, and contribute to Factorial's AI engineering best practices.
Office-first in Barcelona & Madrid, with 20% remote flexibility
A people-first, high-trust culture built on radical candor and ownership
A multicultural team (40+ nationalities) building the next generation of business management software
If you apply, here's what to expect:
A first conversation with our Talent Acquisition Partner. It will be about comparing our expectations and making sure we match on a human level. We will also check our Engineering Rubrics (check them out, they are open!) and the salary in your position.
A second conversation with the team's Engineering Manager. This is about making sure we can work together. Here you will have a conversation about the team, their needs, your profile and how can you complement it. Expect to have a mix of a human and technical conversation.
A Live Engineering Challenge with two Factorial engineers: At Factorial, we're passionate about hiring engineers who can think clearly, communicate well, leverage the best tools, and learn very fast. In this challenge, we're not looking for a finished product, but for how you structure problems, ask questions, use technology, and reason about solutions.
One last coffee-chat with our CTO, where you can get all the answers about Factorial's culture, business vision, or anything else that interests you.
And that's it! Feel free to request any other conversation you want, with team members or to address specific concerns at any time during the process.
The whole process is remote, using videoconferencing tools!
Factorial is a Barcelona-based software company that provides an all-in-one human resources management platform for small and medium-sized businesses. Its cloud-based solution covers HR administration, payroll, time tracking, talent management, and expense management, helping companies digitize and automate their HR processes. Founded in 2016, Factorial has grown rapidly and now serves thousands of customers across Europe, the Americas, and Asia, with a workforce of over 800 employees.
Factorial's headquarters and main engineering hub are in Barcelona, making it a key player in Spain's vibrant tech ecosystem. The company has a strong international presence with offices in Mexico City, São Paulo, and other cities, and its workforce is highly diverse, with employees from over 30 nationalities. For international professionals, Factorial offers a dynamic, fast-paced startup culture, opportunities to work with a global team, and the chance to contribute to a product that is reshaping HR for SMBs worldwide. The company is known for its flat hierarchy, agile work environment, and commitment to employee growth.
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.
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.
