Responsibilities
- Build and ship features on systems used by millions of buyers and sellers — real work, not training exercises.
- Rotate across engineering chapters over 18 months, gaining hands-on experience in Backend (Kotlin/Java), Frontend/Web (React/Angular), and one mobile platform (iOS or Android).
- Rotation in a non-engineering department over 3 months. This will allow you to get to know other parts of the business and gain an understanding of how Wallapop operates as a whole.
- Work with senior and mid-level engineers and cross-functional stakeholders who will mentor you, review your code, and push you to grow.
- Use AI tooling as a first-class part of your workflow — Copilot, Claude, and similar tools are how we work, not an afterthought.
- Participate fully in team life: standups, planning, retros, code reviews.
- Own your learning — flag blockers fast, ask questions freely, and teach back what you're learning.
Requirements
- Fresh graduate — University (e.g., UPC), Grado Superior, or equivalent. This is your first professional engineering role.
- Basic coding fluency — you've built things, you can debug, you understand what your code actually does.
- Curiosity — you ask why, not just how.
- Learning velocity — you pick things up fast and lean into unfamiliar territory.
- Openness to breadth — you're not here to be a one-stack specialist. You want to understand the whole picture.
- Care — you want to do software well, for the right reasons.
- Fluent English — Ability to communicate clearly and effectively with English-only stakeholders across Wallapop.
Benefits
- Permanent contract from day one — you're an engineer at Wallapop, not a trainee on a clock.
- 21 months of structured rotation with real ownership at every stage.
- A dedicated mentor per chapter + a stable Anchor Engineering Manager across the full program.
- AI-native onboarding — you'll be set up with the tooling and context to contribute fast.
- A clear path to becoming a fully fledged Full-Stack Engineer at the end of the 21-month rotation.
- Competitive graduate salary.
- Generous individual learning budget of 2k per year
- Free office meals, lunch selection from different providers

The Challenge
Are you ready to kickstart your engineering career? We are launching our first cohort of our Full-Stack Graduate Program—an immersive, 21-month rotational journey designed to cultivate adaptable, high-impact T-shaped software engineers. At Wallapop, we believe in building solid vertical depth in a core technology while fostering a horizontal, working fluency across the rest of our ecosystem. Over the course of 21 months, you will complete three distinct 6-month rotations through our core engineering chapters—shipping real production code used by millions—alongside a 3-month business immersion rotation: - Backend Chapter (6 months): Deep dive into robust, scalable server-side systems using Kotlin & Java (with Spring Boot, Ktor, AWS, and microservices). - Frontend (Web) Chapter (6 months): Build responsive, elegant, and modern web applications using React & Angular. - Mobile Chapter (6 months): Craft exceptional native mobile experiences on either iOS (Swift) or Android (Kotlin/Java) depending on team fit. - Business Immersion (3 months): Step outside of engineering to complete a rotation in non-engineering departments. This will allow you to get to know other parts of the business and gain an understanding of how Wallapop operates as a whole.
What We’re Looking For
We care more about how you think and learn than about what's on your CV. We're looking for people who are genuinely curious, who want to understand systems rather than just pass tests, and who are motivated by building things that matter.
