Junior Full Stack Developer

Description

**Galadrim** is a startup that designs and develops web, mobile, and AI-powered products. Led by two alumni of *École Polytechnique* who previously worked at Meta, IBM, and Microsoft, we build custom, complex solutions for our clients using agile methodologies. We are over **150 people** across France and Spain, growing at over 50% annually for the past 8 years — and the Spain team *needs you!* By joining us, you’ll have the opportunity to work on a wide variety of projects within a young, tech-passionate team. We are looking for **Full Stack Developers** (web and mobile) to join one or more of our ongoing projects in Spain. Additionally, as our team grows, you’ll have opportunities to take on increasing technical leadership responsibilities. **This role is for you if** * You have 0\+ years of experience. (Yes, you read that right — 0 years!) * You love modern, fluid, and *pixel\-perfect* interfaces. * You’re unafraid to dive into complex business rules and translate them into efficient, optimized algorithms. * You fluently use AI-powered code editors like Cursor or Claude Code to boost your agility and execution speed — while retaining full control over your *codebase*. * You have strong interpersonal skills and are motivated to accompany sales colleagues to meetings to clearly explain technical concepts. * You enjoy teamwork but operate with full autonomy on your tasks. * You pursue technical excellence in everything you do, grounded in solid engineering principles. * You are a native Spanish speaker and fluent in English. Bonus if you speak French! **Your progression at Galadrim** * **Within 3 months:** You’ll already have worked on your first two projects. At Galadrim, we strongly believe in *learning by doing*, so you’ll start contributing to real projects from day one — always supported by a *Tech Lead*. You’ll also be able to participate in international conferences and workshops with the rest of the team. * **By 6 months:** You’ll have mastered our tech stack and methodology, and will be ready to assume greater responsibilities — helping us structure the team (hiring, management, internal tool development, etc.). For context: in our Paris office, we grew from 2 to over 20 engineers in under 3 years. * **Long-term:** You’ll have the chance to directly contribute to scaling our operations in Spain. **Preferred technical stack** Don’t worry if you don’t master all these technologies — the stack varies per project. Below is our most commonly used stack, but it will be adapted based on your level and project needs: * PostgreSQL * Node.js (Adonis, Nest.js, Next.js) * JavaScript / TypeScript * React / React Native * AWS **Benefits** This position is *hybrid* in **Madrid** (4 days in office / 1 remote, accumulable).
