You’ll work on real product features, not mockups. You’ll help design, test, and ship experiences that impact activation, retention, and monetization — blending creativity, usability, and growth thinking.
If you love creating designs that convert, not just look good, this is your place.
READ THIS FIRST — Apply only if you meet this:
- Eligibility: You’re currently studying at a university in Spain (ideally in or near Barcelona) and can sign a "convenio de prácticas". This position is open exclusively for internship agreements.
If you’re not sure whether your university can provide one, please confirm with them before applying, as we’ll automatically filter out candidates who can’t meet this requirement.
Otherwise, feel free to check out our other junior roles on the Carrots Lab LinkedIn page › Jobs where a "convenio" isn’t required.
- Design Impactful User Experiences: Create user flows, wireframes, and prototypes for live Carrots apps, optimizing every pixel for usability, conversion, and delight.

- UX Research & Testing: Conduct usability testing, competitor audits, and heuristic analyses to validate design decisions.
- Growth-Oriented Design: Experiment with paywalls, onboarding, and in-app flows that improve activation, retention, and monetization.
- Design System & Handoff: Maintain and improve the design system, ensure Figma files are clean and ready for dev handoff.
- Data-Driven Creativity: Collaborate with analysts to interpret data and apply insights to design improvements and experiments.

- You’ve launched at least one A/B-tested UX or UI experiment that improved a key metric.
- You’ve contributed components or patterns to the Carrots Design System.
