Senior UX Designer

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 Senior UX Designer based in Barcelona to join our team and lead the design of key digital experiences for one of our biggest and most exciting global clients - a top-tier technology company - working on a large-scale subscription service.

Requirements

-What will your day to day be like?-

You will:

• Own the UX design for multiple initiatives end-to-end, from problem framing through final experience definition - ensuring clarity, completeness, and consistency across flows and touchpoints.

• Define user flows, interaction patterns, and experience structures across key journeys, keeping solutions coherent across the broader ecosystem and aligned with existing patterns and systems.

• Frame design recommendations in terms of measurable business outcomes, connecting UX decisions to revenue, retention, conversion, and customer lifetime value.

• Translate product and business goals into clear UX strategies and communicate rationale effectively to stakeholders.

• Collaborate closely with UX and UI designers to ensure consistency and quality across the experience, and with the Project Manager to align on priorities and delivery.

• Produce high-quality UX artifacts such as flows, wireframes, and interaction specifications - ensuring designs are complete and ready for UI production and development.

• Leverage and contribute to existing patterns and design systems, ensuring consistency and scalability across initiatives.

-What are we looking for?-

• Senior UX professional with strong product thinking and a proven ability to tie design decisions to business outcomes (revenue, conversion, retention, churn reduction).

• Experience building business cases for design investments and communicating UX value to non-design stakeholders.

• Background in subscription, SaaS, or consumer services environments.

• Comfortable working with US-based teams across time zones.

• Strong communication skills with the ability to build trust with Product and stakeholders.

• Strategic mindset combined with hands-on execution capability.

• Experience with end-to-end journey design across multiple touchpoints.

• Experience collaborating with UI designers and supporting production and handoff processes.

• Fluent in English (written and spoken), with the ability to actively participate in discussions, present work, and explain decisions with US-based stakeholders.

• Portfolio demonstrating ownership of end-to-end UX workstreams, strong UX artifacts (flows, wireframes, interaction models), and clear examples of business impact tied to design decisions.
