Software Engineer - Graduate Program

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: Backend (Kotlin/Java), Frontend/Web (React/Angular), and one mobile platform (iOS or Android)
• ▹Complete a 3-month rotation in a non-engineering department to understand how Wallapop operates as a whole
• ▹Work with senior and mid-level engineers and cross-functional stakeholders who mentor you, review your code, and push you to grow
• ▹Use AI tooling (Copilot, Claude, and similar tools) as a first-class part of the workflow
• ▹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 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

Soft skills

What we offer

• ▹Three-tier mentorship model: a dedicated Anchor Engineering Manager for the full 21-month journey, a rotating Chapter Mentor for daily pair-programming, and a Rotation Team Manager to integrate you into cross-functional agile rituals
