Familiarity with version control systems like Git, build tools such as Maven or Gradle, and experience with IDEs like IntelliJ IDEA or Eclipse are common technical requirements. Strong problem-solving, eagerness to learn, and effective teamwork are standout soft skills in this role. These skills ensure you can write reliable code, collaborate efficiently, and adapt to evolving technical challenges in software development projects.
