They often lead development teams, architect solutions, and ensure that software meets both technical and business requirements. Their responsibilities also include code reviews, mentoring junior developers, and optimizing application performance. Typically, they have several years of experience and a deep understanding of Java frameworks and best practices.

What are the key skills and qualifications needed to thrive as a senior Java engineer?
