Labhouse is a fast-growing startup that builds, launches, and scales its own AI & Productivity Apps, operating under a subscription-based business model.

Based in Barcelona, Labhouse was founded by Andrés Bou and Horacio Martos (Co-Founders of SocialPoint).

We operate at the intersection of mobile technology, AI, and product-driven growth, with a strong focus on experimentation and performance.

Would you like to make an impact as part of a company that builds the best mobile apps used by millions of users worldwide? If so, discover your next challenge below.

About the Role:

As UI/UX Director, you will set the design vision for Labhouse and be accountable for the quality and impact of the experience across our whole app portfolio. Working as a direct partner to the CEO and Head of Product, you will decide how design is done in the company: the standards, the process, the team and the level of craft that sets our apps apart.

This is a leadership role with deep craft and hands-on work. You will set the strategy and build the design team, and still step in on the work that matters most, from defining a new app's concept to reviewing the final pixels, animations and store assets. You will own the design system across all products, make sure every launch meets a best-in-class bar, and tie design decisions directly to business results: activation, retention, conversion and store performance.

What you'll own:

• Design vision and strategy: define the UI/UX principles, visual language and quality bar for the whole portfolio, and bring them to every product decision at leadership level.

• 0→1 launches: lead the experience for new apps from concept to launch, including research, benchmarking, prototyping and validation with real users.

• Craft and production quality: set the standard for every asset we ship: UI, illustrations, icons, motion, animations, store screenshots and videos, and make sure what engineering ships matches what was designed.

• Measurable design impact: work with Product and Data to turn onboarding, paywall, core flow and store-asset improvements into measurable gains in activation, conversion, retention and store conversion rate.

• Design system at scale: own a portfolio-wide design system that lets us launch new apps faster while keeping consistency and craft.

• AI-native design workflows: introduce AI tools into research, ideation, asset creation and prototyping to multiply the team's output.

• Build and scale design teams: hiring, mentoring and developing senior talent.

About You:

Craft and technical expertise:

• Solid track record in product, UX/UI, or visual design, including leading design teams or a design function.

• Experience leading the design of consumer mobile apps from scratch to scale (ideally millions of users), with clear business impact you can quantify.

• A portfolio that shows both exceptional craft and strategic thinking: from early concepts to shipped, high-performing products.

• An artistic eye for color, composition, typography and motion, able to lead and review any type of asset.

• Mastery of Figma and Adobe Creative Suite, and the ability to jump in hands-on.

• Deep knowledge of iOS and Android design guidelines, and of how to go beyond them to create distinctive experiences.

Product and business focus:

• Experience owning design strategy at leadership level and influencing founders and executives on product direction.

• A product-first mindset: you think in user problems, hypotheses and outcomes, not just screens.

• Comfortable working with data: you use analytics, A/B tests and store metrics to guide and defend design decisions.

• Strong understanding of consumer app monetization (subscriptions, paywalls, onboarding) and how design moves it.

• Self-driven and entrepreneurial, with high ownership and comfort working directly with founders in a fast-paced environment.

Communication:

• Fluent in spoken and written English

• Ability to collaborate effectively with cross-functional teams, including engineering, product, and marketing.

Nice to Have:

• Experience in a portfolio or app studio model, managing design across several products at the same time.

What we Offer:

• Remote work from anywhere in Spain. If you are based in Barcelona, we would love for you to join us at the office (Barcelona Tech City) at least two days a week.

• Flexible working hours.

• Permanent contract with competitive compensation.

• High-end equipment for your development.

• A top entrepreneurial team in a dynamic startup environment.

• Opportunity to lead, grow, and take on big challenges.

• Work with cutting-edge technologies, including the chance to integrate AI models into new apps.
