Senior Frontend Engineer, Barcelona

Our stack is composed of micro frontends using ReactJS (TypeScript), Zustand, orchestrated with NX and with our in-house design systems, and we believe that if you have strong front-end experience in any major frontend framework, you'll fit right in. Your role will include:

• Taking ownership of major front-end initiatives
• Leading complex technical projects in collaboration with leadership.
• Driving a complete revamp of our client interfaces.
• Building and maintaining our in-house design systems.
• Tackling technical debt and ensuring long-term scalability.
• Developing reliable, scalable solutions for one of our key product verticals.

You have 5+ years in frontend development, with deep experience in SaaS or product companies. You take initiative, own your work, and actively look for problems to solve. You're a strong communicator and proficient in English.

If ReactJS and micro frontend aren't already in your toolkit, you're eager to pick them up.
