What is a backend software engineer?

Backend software engineers are professionals who design, build, and maintain the server-side logic, databases, and application programming interfaces (APIs) that power web and mobile applications. They focus on ensuring that data is stored, retrieved, and processed efficiently, and that the application's functionality works seamlessly behind the scenes. Backend engineers often work with programming languages like Java, Python, or Node.js, and use frameworks and tools to build scalable and secure systems. Their work is crucial to supporting the user-facing parts of applications developed by frontend engineers.
