Hello!
At Factorial we're looking for a Junior Software Engineer to join our Platform Domain and help us boost our wider organisation to the next level.
Since you'll be taking AI-generated applications and prototypes to production, you will interact with a very dynamic stack. You will work with modern web frameworks (like Next.js and TypeScript), backend tools, and foundational cloud infrastructure. It is the ultimate playground to learn how apps are built, deployed, secured, and maintained.
Are you ready to be part of one of the most enabling teams? 🚀
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.
What You'll Be Doing?
The Enablement sub-squad is a brand-new, high-impact initiative within the Platform/Infrastructure team. As our company scales past 1,700 people, we are seeing an explosion of creativity from non-product teams—like Marketing, Sales, Partnerships, and the wider org. They are coming up with awesome ideas and building prototypes using AI for dashboards, websites, and tooling for their daily operations.
But sometimes, they lack the technical knowledge to get these applications production-ready. That’s where you come in! You will work closely with the Infrastructure team (acting as a bridge rather than a traditional full member) to support these non-product teams, turning their great ideas into fully deployed, stable internal products.
You will be:
interacting with non-technical stakeholders. Patience and soft skills are a must. Writing documentation and video tutorials. Organizing live training sessions.
understanding and challenging project rationales. Proposing simpler alternatives, pointing to existing tools or, when it makes sense, building an amazing tool that will provide value quickly.
maintaining, updating, implementing software engineering best practices, both for backend and frontend projects.
contributing to CI (building) and CD (deploying) workflows.
We are looking for a person who loves to think about the user & create awesome solutions to solve problems and know tech is only a tool to achieve this goal.
We are looking for a team player and great communicator, a person who is comfortable helping non-technical teammates, translating their awesome ideas into stable solutions, and raising the hand first when anyone needs help.
A true owner with a critical eye. We are looking for a person who likes proposing new things, taking an AI-generated prototype, and being responsible for building, deploying, and validating it for real-world daily operations.
Entrepreneurial mindset even if you didn't found your own company, having this passion is crucial to join our team. Things will move fast, priorities might shift based on organizational needs, and you have to be happy working at light speed.
A hunger to grow: This role is a massive launchpad for your career. We are looking for someone eager to learn and evolve. Depending on your craft and interests, in a year your growth path could lead you to become a DevOps Engineer in the Enablement team, a Software Engineer in Revenue Operations or Growth, or a Product Engineer!
How We Work 💻 (Barcelona Office strongly preferred)
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 approach.
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.
Due to the collaborative native of this position, we will give priority to candidates based in Barcelona over Madrid and Coruña.
At Factorial we don't evaluate you by years of experience but by your knowledge and skills.
We use our Career Path with a rubric framework where we define what is expected for each experience level and skill. This framework allows you to know your current level and what you need to keep growing. We love transparency, so our Career Path includes the salaries for each level, which we share during the first interview to ensure alignment.
