Our ventures have raised over $1.5B in funding, generated more than $3B in shareholder value, and today employ more than 3,000 people.
We are looking for an AI-native Product Designer to join our Product & Tech team in Barcelona.
This is not a traditional design role. We want someone who is deeply product-minded, highly hands-on, and excited about designing in a world where AI changes how products are conceived, prototyped and shipped. You should be comfortable not only designing interfaces, but also using AI tools, agentic systems and AI-assisted building workflows to move faster, explore more ideas, and help bring products to life.
Design end-to-end product experiences, from discovery and flows to polished UI and detailed interactions.
Turn complex user needs, business goals and data into simple, intuitive and high-quality product experiences.
Own the user experience across the full product lifecycle: research, ideation, prototyping, testing and execution.
Work closely with product managers, engineers, data scientists, growth, sales and marketing to define and ship new products and features.
Create clear, implementation-ready designs that engineers can build from with speed and confidence.
Build and evolve design systems, interaction patterns and reusable components.
Prototype fast and often, using both traditional design tools and AI-powered tools to validate ideas early.
Use AI workflows and agentic systems to improve how you research, generate concepts, test ideas and accelerate execution.
Act as the voice of the user while balancing product ambition, technical feasibility and speed.
Help the team explore new ways of working at the intersection of design, product and AI.
You have experience as a Product Designer, with a strong portfolio showing end-to-end product thinking across multiple projects.
You are an excellent UX/UI designer, but also highly pragmatic and execution-oriented.
You are AI-native in the way you work: you actively use AI tools to research, think, prototype, write, generate, iterate and ship faster.
You are comfortable using or experimenting with agentic systems, AI copilots, automation workflows, and multi-step AI tools as part of your design process.
You have built prototypes yourself, or used AI-assisted coding / low-code / no-code tools to bring ideas to life without always depending on engineering first.
You enjoy prototyping and testing ideas quickly, and you are excited by the idea of turning concepts into working experiences in days, not weeks.
You can go from ambiguity to clarity and are comfortable working in fast-moving, early-stage environments.
You communicate clearly and can influence cross-functional teams with strong reasoning and product judgment.
You are comfortable with research, user testing, analytics, experimentation, competitor analysis and defining product metrics.
You have solid experience with Figma.
You care deeply about product quality, user empathy and craft.
You are fluent in Spanish and English.
You have worked on 0→1 products, startups, venture studios, or fast-paced product teams.
You have built internal tools, growth experiments or MVPs yourself using AI-assisted workflows.
You are genuinely excited about how AI is reshaping product design, product development and company building.
Full-time role based in Barcelona.
The opportunity to work on ambitious products with top-tier founders and operators.
A young, fast-moving and highly entrepreneurial environment.
Exposure to multiple ventures and real product-building from day one.
Strong growth opportunity within one of Europe’s leading venture studios.
Beautiful seaside offices in front of La Barceloneta.
