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, not a feature to bolt on later
- Want to build and ship, not debate and document
- Care about whether the thing they built actually worked and what is the exact value they’re adding.
Ready to be part of the challenge?
We are looking for a Product Engineer to join our CIAM (Customer Identity and Access Management) team at Factorial. You will work on both sides of the stack but with more focus on the backend side.
About the team
Our Engineering team is the engine behind Factorial, crafting the tech that makes HR simple, fast, and reliable for thousands of companies. If you love solving hard problems and want to build something that truly matters, come build it with us.
We're a team of 200+ Product Engineers building Business Management solution that actually works for the people using it. Our core stack is Ruby on Rails and React but the interesting work right now is what we're building on top of that: agentic workflows, LLM-integrated features, systems that behave probabilistically rather than deterministically.
You'll be on the Customer Identity and Access Management (CIAM) team owning areas such as: Authentication, Single Sign-On, Multi-Factor Authentication, Authorization, Permissions, Auditing. Sitting within the Platform Domain, you will lay the foundations for external and internal users to extract and deliver value from our platform.
The role requires full ownership of your area, a self-starter attitude, dealing with uncertainty and combining a strategic product mindset with a focus on execution. If you feel as if you belong in a product-first company, want to work with a world-class team of designers and developers, and deliver the future of B2B software, we should talk!
As a Senior Engineer at Factorial, you'll be part of a team of 200+ Product Engineers. We look for talented people who are curious, proactive, and have great communication skills. People who are at the forefront of developing tools that help teams become the best versions of themselves.
You'll work in a multicultural, English-speaking environment where your technical acumen, creative problem-solving abilities, and passion for user-centric products will directly contribute to our mission of improving HR processes for SMEs worldwide. We have offices in Barcelona and Madrid so as long as you’re willing to in our Barcelona offices, or mixing both.
Our stack is Ruby on Rails and React.
But, hey! Don't let unfamiliarity with these specific technologies hold you back! If you're someone eager to learn, you have navigated through diverse technical challenges throughout your career, and have a hunger for building new solutions that help cultivate highly satisfied, productive, employees, then we want to talk to you.
How We Work (Barcelona or Madrid Office)
At Factorial, we believe the best products are built when people come together, in person to collaborate, challenge ideas, and move fast. That’s why our Engineering Teams follows an office-first, flexible schedule.
We work on-site several days a week, using that time to connect, align, and innovate as a team. However, we also understand the importance of focus and flexibility, so we support remote work when it makes sense - whether for deep work, personal needs, or just a change of scenery.
This balance helps us stay agile, creative, and closely connected, while giving everyone the space to do their best work.
