Software Development Engineer II

Are you excited about building software that operates at massive scale and directly impacts millions of customers? As a Software Development Engineer II at Amazon, you will design, build, and deliver software solutions that solve real problems and create meaningful value. You will own features across the full development lifecycle - from understanding customer needs through design, implementation, testing, deployment, and operations. This is a role where your technical contributions matter: you will write high-quality code, mentor fellow engineers, and help shape the direction of the systems you work on. If you are a collaborative, curious engineer who thrives on turning ambiguous problems into clean, maintainable solutions, we want to hear from you.

Key job responsibilities

• Design and implement software features across the full development lifecycle, including working backwards from customer needs, architecting solutions, writing production-ready code, testing, deploying, and operating services at scale.
• Identify root causes of operational issues and drive permanent fixes, while continuously improving system reliability, performance, and maintainability for your team"s software.
• Mentor and coach other engineers through code reviews, design discussions, and knowledge sharing, helping raise the overall quality bar of the team"s output.
• Evaluate technical tradeoffs between competing approaches, balancing short-term delivery needs with long-term architectural goals, and collaborate with stakeholders to ensure solutions align with business and customer priorities.
• Write clear documentation for the software you build - covering design decisions, operational runbooks, and system architecture - so that others can maintain and extend it effectively.

A day in the life

You start your morning reviewing pull requests from teammates, offering constructive feedback that helps the team ship better code. After a quick standup, you dive into building a feature you scoped last week, writing clean code and pairing with a teammate on a tricky integration point. After lunch, you join a design review where you help simplify a proposed architecture, then spend time investigating an operational metric that looks off - tracing it to a root cause and drafting a fix. Your day balances heads-down coding with collaborative problem-solving.

About the team

Our team builds software that customers and internal partners rely on every day. We care deeply about operational excellence, code quality, and creating an inclusive environment where every engineer"s perspective is valued. We believe great software comes from clear thinking, open collaboration, and a willingness to learn from both successes and failures. As we look ahead, we are focused on scaling our systems, improving the customer experience, and investing in the tools and practices that help our engineers do their best work. This is a great time to join and make a lasting impact.
