Job description

We are not looking for a long list of skills and technologies. Our stack is Ruby on Rails for the backend and React/React-native for the front end.

If you´re looking for new challenges in a people-first company regardless where you live, keep reading!

What You´ll Do

Collaborate closely with Product Managers and Designers to build user-centric, maintainable solutions.
Develop features across the full stack (frontend/backend).
Participate in code reviews, pair programming, and team rituals to maintain high engineering standards.
Take ownership of tasks and deliver independently or in small groups, with growing autonomy.
Debug production issues and contribute to the stability and performance of the platform.
Work in agile teams with clear priorities and a shared roadmap.
Learn continuously and contribute to team knowledge-sharing sessions.
Contribute to planning, estimation, and retrospectives., At Factorial, we don´t evaluate you by the years of experience you have; we assess your knowledge and skills. How? We have a Career Path with a rubric framework where we define what is expected for each experience level and skill. This framework allows you to know at which level you are right now and what you need to keep growing. As we love transparency, our Career Path includes the salaries for each level, and we share them during the first interview to make sure we´re aligned.

Your daily life with us

You´ll start with a 2-week onboarding period, where you will:

You will be learning about Factorial, our product, our team, and our clients
Pair with each member of the team at least once to see their current initiatives
Solve low-stakes bug tickets or quick wins
Commit early and often, thanks to our dev environment
Be fully integrated in the team´s rituals from day 1

You will be a Product Engineer, taking ownership of big initiatives, and being interested in the outcome, not just the output. About the outcome, you´ll also work with your team members to establish goals and plan a quarterly roadmap, putting special attention to the technical needs of our domain.

You will be involved in customer calls to learn about their pain points & needs.

You will review code daily and get feedback on your own code at every pull request, from all team members, including juniors.

You will learn from the entire team, both on technical topics (performance, architecture...) and core skills, in an environment driven by engineering quality. You will also mentor junior team members and help them learn from your experience.

How We Work

We follow an office-first, flexible approach (80 -20%) because we believe the best products are built when people collaborate face-to-face. We work on-site several days a week in our Barcelona HQ (or Madrid office) to connect, brainstorm, and ship together, while keeping flexibility for deep work and personal balance.

Requirements

At Factorial, we are a team of +200 very talented Full-stack developers. We look for smart people who are curious, proactive and have great communication skills., Experience with at least one modern backend language or framework (e.g., Ruby, Python, Node).

Good experience with React, JavaScript, or TypeScript on the frontend.
Ability to collaborate in English (spoken and written) across cross-functional teams.
A strong sense of ownership and a mindset focused on outcomes, not just delivery: we´re looking for an engineer, not a programmer.
You´re pragmatic: you know when to ship fast and when to raise the quality bar.
You´re a team player who thrives in a feedback-driven, transparent culture.
