React Javascript Python Agile Cloud Coumputing Ruby TypeScript Ruby on Rails Office

We´re looking for a Mid Software Engineer to join one of our cross-functional engineering teams.

Our teams are mission-driven, diverse, and passionate about solving real-world problems for thousands of companies globally. While the domain you´ll work in may vary (e.g., Operations, Talent, Finance, Growth), the expectations, autonomy, and support will be consistent.

The Engineering team at large

At Factorial, we are a team of +150 very talented fullstack 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 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.

Your Profile
- 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.

At Factorial we don´t evaluate you by the years of experience you have, we evaluate 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´re 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 it during the first interview to make sure we´re aligned.

For this mid-level position, the annual gross salary is 425000. This includes a base salary of 400000 and a variable pay of up to 25000 annually (paid quarterly), depending on the company´s goals.

Your daily life with us
- You´ll start with a 2 weeks onboarding period, where you will:
- You will be learning about Factorial, our product, our team, our clients
- Pair with each member of the team at least once, to see their current initiatives
- Solve low-stake bug tickets or quick wins
- Commit early and often thanks to our cloud 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 pains & 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.

Benefits

We care about people and their well-being:

- Save expenses with Cobee and get your salary in advance with Payflow
- TaxDown to simplify your taxes and maximize your savings!
- Healthy life with Gympass and Alan as private health insurance
- Language classes with Yolk Academy & Factorial Language exchange
- Syra and Apeteat discounts!
