We believe in a world where collaborative economy is mainstream. This is what drives us. 💫 Wallapop operates in Spain, Italy and Portugal, offering a catalogue of several hundreds of millions of products and services. Powered by technical innovation and continuous improvement, we bring together the scale & trust of classifieds with the marketplace’s convenience & reach. 🌱 Our mission is to enable a connected trade ecosystem, making 2nd-hand the norm through smart use of technology. 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. You will be supported by a comprehensive, three-tier mentorship model including a dedicated Anchor Engineering Manager for your entire 21-month journey, a rotating Chapter Mentor for daily pair-programming, and a Rotation Team Manager to integrate you into cross-functional agile rituals. We also treat AI-native developer tooling (GitHub Copilot, Claude, etc.) as first-class citizens to help you ramp up and contribute fast! WHAT YOU WILL DO 👇 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. 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. * 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. WHAT WE OFFER 🚀 * 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. * Wallapop's standard benefits package (detailed below!).
