What does a backend infrastructure engineer do?

A Backend Infrastructure Engineer is responsible for designing, building, and maintaining the foundational systems and services that support software applications. They focus on scalability, reliability, security, and performance of backend systems, such as databases, servers, APIs, and cloud platforms. Their work ensures that applications can handle large amounts of data and traffic efficiently, and they often collaborate with other engineers to deploy and monitor these services. Additionally, they may automate infrastructure processes and implement best practices for system architecture and monitoring.
