The terms describe two distinct, yet sometimes overlapping, engineering roles within Amazon. One focuses on the design, implementation, and maintenance of the underlying infrastructure and systems that support the company’s services. The other concentrates primarily on developing and maintaining specific software applications and features. For instance, a system engineer might work on optimizing the performance of AWS data centers, while a software engineer would build and maintain a specific service like Amazon Prime Video.
Understanding the difference is crucial for candidates applying to Amazon, as it influences the necessary skill sets and career trajectory. Historically, the distinction has become more pronounced as Amazon’s infrastructure has scaled and become more complex, leading to greater specialization within its engineering teams. This differentiation helps Amazon ensure optimal performance, reliability, and scalability across its diverse services.
