Software Development Engineer II

Are you passionate 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 features that solve real-world problems while shaping the technical direction of the systems you own. You will work across the full software development lifecycle — from understanding customer needs to deploying and operating production systems — and your contributions will have a meaningful effect on how customers experience our products.

This role is ideal for engineers who thrive on turning ambiguous problems into clear, well-designed solutions. You will collaborate with cross-functional partners, mentor fellow engineers, and continuously raise the bar on code quality and operational excellence. If you are a self-starter who is curious, adaptable, and eager to grow your impact, we want to hear from you.

Key job responsibilities

• Design and implement software solutions across the full development lifecycle, including requirements gathering, architecture, coding, testing, deployment, and ongoing operations, ensuring high-quality and maintainable code.
• Collaborate with customers, stakeholders, and cross-functional teams to understand business needs and translate them into scalable, well-documented technical solutions that balance short-term delivery with long-term extensibility.
• Actively participate in code reviews, providing constructive feedback to teammates and coaching others on best practices for producing clean, reliable software.
• Identify root causes of operational issues and drive permanent fixes, while continuously improving your team's operational processes and system reliability.
• Evaluate new technologies and approaches, recommend adoption where appropriate, and contribute to design reviews that strengthen the overall architecture of your team's systems.

A day in the life

You start the morning reviewing deployment metrics and triaging any operational alerts from overnight. By mid-morning, you are deep in a design discussion with teammates, whiteboarding a solution for a new feature that requires careful trade-offs between performance and maintainability. After lunch, you pair with a newer engineer on a code review, walking through patterns that improve readability and testability. Later, you push a feature increment to production and verify its behavior through automated tests and real-time dashboards.
