• Collaborate with stakeholders to shape product direction and make architecture decisions.

What we're looking for

• Experience with backend technologies and RESTful APIs, including Spring Framework / Spring Boot

• Solid understanding of computer science fundamentals (data structures, algorithms, system design)
• Passion for building clean, maintainable code and modern software development practices (CI/CD, TDD, DevOps)
• Strong communication and collaboration skills
• A drive to learn and improve - both yourself and the systems you build
