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.

Is this something you feel identified with?

We're currently looking for a UX Designer, AI Experiences to join our team and help shape the future of AI-powered SaaS experiences — designing intuitive, user-centered interfaces while actively leveraging AI throughout the design and product development process to accelerate innovation, improve quality and deliver user value faster.

You will:

• Design AI-powered user experiences for SaaS platforms — including copilots, agents, intelligent assistants, workflow automation, conversational interfaces and predictive experiences.

• Define interaction patterns that effectively balance human control with AI-generated recommendations and actions.

• Create intuitive experiences that build user trust through transparency, explainability and appropriate feedback mechanisms.

• Conduct and synthesise user research to identify opportunities and improve overall user experience solutions.

• Create detailed design specifications and documentation that facilitate efficient engineering implementation.

• Develop scalable design assets, component definitions and interaction patterns that streamline handoff to development teams.

• Leverage AI tools throughout the design lifecycle — accelerating discovery, ideation, prototyping, content creation, documentation and validation.

• Apply AI-driven workflows to increase design efficiency while maintaining high-quality user experiences.

• Use AI to generate and iterate on wireframes, user flows, design concepts, UX copy and specifications.

• Continuously evaluate and adopt new AI tools, methodologies and frameworks that improve team productivity.

• Extend and evolve design systems to support emerging AI interaction patterns — defining reusable AI experience patterns, guidelines and best practices.

• Contribute to organisational standards for AI-native product design and advocate for responsible, ethical and user-centered AI experiences.

This is a unique opportunity to bring your craft into projects that generate real, measurable impact — working alongside a global team that turns complexity into solutions worth building. If that sounds like your kind of challenge, we'd love to meet you.
