• Design Patterns: A firm grasp of object-oriented programming, distributed systems principles and methodologies like  DDD using architecture design patterns like Hexagonal, Event-Driven and Microservices.
• Quality First: A strong track record of using engineering best practices, including Clean Code, TDD/BDD, and deep observability.
• AI-Augmented Development: Proven experience in critically using AI coding agents (e.g., Claude Code, Gemini Code, GitHub Copilot) to accelerate delivery without compromising code integrity or security.

Technical Stack

• Modern Frontend: Advanced experience with React and TypeScript for building complex, responsive web applications.
• Backend & Tooling: Good understanding of Node.js and experience in using it for developing web services, internal libraries (npm packages), and CLI applications.
• API Design: Solid experience designing and implementing robust REST APIs.
• Data & DevOps: Professional experience with PostgreSQL (performance and scalability) and a "DevOps mindset" regarding CI/CD pipelines.
• Bonus Points: Knowledge of Kotlin/Spring Boot, Python, or Generative AI frameworks (Langchain, RAG pipelines) is a significant plus.

Soft Skills

• Bias for Action: A "can-do" attitude with a focus on product understanding to ensure delivery and continuous improvement.
• Collaborative Spirit: A strong team player who values knowledge sharing and is always willing to help others grow.
• Communication: Clear written and verbal communication skills, essential for a cross-functional platform environment.

What’s in it for you:

• Accelerate your career growth by joining one of Europe’s most talked about disruptors.
• Employee benefits that range from a competitive personal development budget, work from home budget, discounts to fitness & wellness memberships, language apps and public transportation. 
• Come together with your team in the office for a dedicated day of teamwork each week, plus another day of your choice, and enjoy the flexibility of remote work the rest of the time. Some roles may require additional in-office presence.
• As an N26 employee you will have access to a Premium subscription on your personal N26 bank account. As well as subscriptions for friends and family members.    
• Additional day of annual leave for each year of service.
