Familiarity with version control systems like Git, cloud platforms (AWS, Azure), and containerization tools such as Docker is commonly expected, along with relevant certifications. Strong problem-solving abilities, effective communication, and the ability to collaborate in agile teams distinguish top performers in this role.
