Are you excited about building software that impacts millions of customers? Do you enjoy solving complex technical problems while collaborating with a talented team of engineers? We're looking for a Software Development Engineer II to join Amazon and help design, build, and operate systems that matter at scale.

A day in the life Your day begins by reviewing operational metrics and addressing any alerts from the systems you own. You then join your team's standup to align on priorities before diving into design or implementation work. You might spend the morning writing code for a new feature, then shift to reviewing a teammate's pull request in the afternoon—offering feedback that helps them grow. You regularly collaborate with product and engineering partners to refine requirements, and you evaluate opportunities to integrate generative AI tools where they can improve productivity.
