About the role

We are building the infrastructure that defines the new era of corporate wellbeing. Backed by Itnig, our mission is to make it easy for SMEs to manage employee benefits in a 100% centralized way, eliminating administrative complexity. We position ourselves as the trusted infrastructure for major industry players, and now we are looking for talent to help us bring this capability to all companies.

We are already the trusted infrastructure for industry leaders such as Factorial, and our mission is to bring this capability to all companies to help them compete for the best talent.

To achieve this, we are looking for versatile professionals with a product-driven mindset and a desire to make an impact. We are a team of problem solvers, naturally curious, with a strong growth culture where collaboration, the exchange of ideas, and collective evolution come first.

What you'll do

We are not looking for someone who just "participates" in the project, but rather someone who…

We are looking for a proactive person who wants to take responsibility and grow together with the project itself.

Your main challenge will be to support your frontend teammates in development, but you will also need to roll up your sleeves and do other things when the situation calls for it.

On a day-to-day basis, this means:

  • Collaborating with product managers and other engineers to create the best experience for our clients within our next-generation frontend application.

  • Ensuring operational excellence of services/applications.

  • Understanding how our business works and how products add value to our clients.

  • Learning and sharing experiences about new technologies and trends, and how we can leverage them in current and future products.

  • Collaborating and sharing knowledge with other team members.

What we're looking for

Soft Skills

  • Good technical communication.

  • Ability to work with moderate (not constant) supervision.

  • Good judgment when asking for help and proposing simple improvements.

  • Conversational English to communicate with clients and partners outside Spain.

Technical Skills

  • Mastery of modern JavaScript (ECMAScript 2024+) and TypeScript in strict mode.

  • Solid experience with React 19+ and its current model: Server Components, Suspense, Actions, and streaming SSR. Experience with meta-frameworks (Next.js App Router, React Router 7 / Remix, Astro) is valued.

  • Modern, performance-conscious styling: Tailwind, CSS Modules, or zero-runtime solutions.

  • Unit and E2E testing, with Testing Library as the foundation (e.g., Vitest, Playwright; Jest/Cypress are also valid).

  • Fluid and critical use of AI-assisted development tools in daily work: agentic assistants, good prompting judgment, and the ability to review, validate, and take ownership of generated code.

Nice to have

Nice-to-Have Requirements

  • Experience with agile development methodologies (SCRUM).

  • Aligned with our company values.

What you'll get

We believe that if you are a person with semi-senior experience, you will know exactly what you are looking for professionally. That is why our proposal will be clear from the start:

  • Salary: We will be 100% transparent about the salary range, because we want your semi-senior experience to be compensated taking into account Bilbao salaries.

  • Work model: Hybrid and flexible. Some days you will need to come to the office, yes, but half the month you can work remotely from home.

  • Real wellbeing

    • Health insurance (Alan): Company-funded, with reimbursement for physiotherapy, dental, psychology, nutrition, and optometry.

    • Flexible compensation (Factorial Benefits): So you can save on food, transport, or childcare.

    • If you get sick: We cover 100% of your salary for the first 3 days.

  • Disconnect: Your birthday is a day off. On top of your vacation days (23 days).

  • Galatea tortilla: On Thursdays when we go to the office, we go out for a tortilla together.

  • Multiculturalism: The team is made up of people with different backgrounds, expertise, and nationalities.

  • Off Site & activities: There are times during the year when we do other types of activities outside the office.

How you'll work

full-time

Permanent

Visa & relocation

  • VISA: We sponsor your VISA and that of your partner/family if you are not a European resident.

    • Don't live in Europe? Don't worry, if we think you are a good fit, we will find a way to work together.
