## About the Role

Do you have experience in TypeScript?, Do you have a Master's degree?, * Strong fluency in modern JavaScript/TypeScript, with React and Node.js.

 * Solid understanding of, or a strong interest in, full stack development and cloud infrastructure (PostgreSQL, Azure, AWS, Docker…).
 * You write clean, maintainable, reusable code with a focus on best practices, testing, and long-term scalability - and you can architect, review, and debug complex systems with strong judgment.
 * A product-level thinker - you reason about users and outcomes, and you have opinions about what to build.
 * You believe the future of engineering is building systems that write code, and you already build this way - with real, hands-on experience using AI coding tools like Claude Code or Cursor. You don't need to be a master of it yet, but it shouldn't be new to you.
 * High agency, with a drive to keep improving your craft and to share what you learn with the team.
 * A collaborative mindset, able to work autonomously in a small, fast-paced team. Comfortable working in English.

Nice to have:

 * Experience with Python and/or machine learning.
