UX Designer & AI Expert

We are Nacar.

A solution-first creative partner helping ambitious organizations shape and deliver the right products, services and experiences — with clarity, rigor and creative excellence.

Rooted in Palo Alto, Barcelona, and with studios in Bilbao, Guadalajara, Porto Alegre and China, we're a global team of 130+ Nacarians from more than 23 nationalities. This role will be based in our Barcelona studio.

Twenty years, 70 design awards and 10+ client ecosystems later, we've learned that creativity is only worth something when it turns into real solutions. That's why we work in a way that connects craft with systems — building things that don't just look right, but perform, scale and generate measurable value for our clients.

A Nacarian is a creative orchestrator, shaped by Criteria, Adaptability and Ownership. Someone who reads complexity, anticipates what matters, and moves fast with intent. We come from different disciplines — strategy, research, industrial and digital design, brand, service, engineering — but we share the belief that great ideas only matter when they become real.

Nacar is entering a new chapter. We're strengthening our capabilities, growing into new markets, and building the organization that will shape what's next. With a hybrid work model and flexible hours, we're powered by a culture of communication, collaboration and ownership — with the ambition of becoming the trusted creative decision partner for the leaders redefining the future of their industries.

If you're excited by building — not just joining — this is a great moment to be here.
