Mid​/Senior Software Engineer

Mid/Senior Software Engineer

Hello,

We are looking for a Mid/Senior Software Engineer to join us in building a new product:
Backoffice.

The Engineering team is large and collaborative. 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.

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 of where you live, keep reading!

• 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.

• Experience with at least one modern backend language or framework (e.g. Ruby, Python, Node).
• Good experience with React, JavaScript, or Type Script 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.

• You will start with a 2‑week onboarding period where you will learn about Factorial, our product, our team, and our clients.
• You will pair with each member of the team at least once to see their current initiatives.
• You will solve low‑stakes bug tickets or quick wins.
• You will commit early and often, thanks to our dev environment.
• You will be fully integrated in the teams rituals from day 1.

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.

• Save expenses with Cobee and get your salary in advance with Payflow.
• Tax Down to simplify your taxes and maximize your savings!
• Healthy life with Gympass and Alan as private health insurance.
• Language classes with Yolk Academy and Factorial Language exchange.
• Syra and Apeteat discounts.
• Breakfast in the office, organic fruit and free caffeine and theine.
• Flexible schedules, pet friendly and no dress code.
