Do you want to solve real customer problems through innovative technology? Do you enjoy working on scalable services in a collaborative team environment? Do you want to see your code directly impact millions of customers worldwide?

At Amazon, we hire the best minds in technology to innovate and build on behalf of our customers. Customer obsession is part of our company DNA, which has made us one of the world's most beloved brands.

Our Software Development Engineers (SDEs) use modern technology to solve complex problems while seeing their work's impact first‑hand. The challenges SDEs solve at Amazon are meaningful and influence millions of customers, sellers, and products globally. We seek individuals passionate about creating new products, features, and services while managing ambiguity in an environment where development cycles are measured in weeks, not years.

At Amazon, we believe in ownership at every level. As an SDE‑I, you'll own the entire lifecycle of your code - from design through deployment and ongoing operations. This ownership mindset, combined with our commitment to operational excellence, ensures we deliver the highest quality solutions for our customers.

• Conduct code reviews as a core engineering practice, providing constructive feedback and validating correctness.
• Contribute to clear and accurate technical documentation.
• Use GenAI and AI‑powered tools to enhance development productivity, and critically validate, verify, and integrate AI‑generated code, exercising sound judgement about when to trust AI output.
• Write clean, maintainable code following best practices and design patterns.
• Work in an agile environment practicing CI/CD principles while participating in operational responsibilities including on‑call duties.
• Demonstrate operational excellence through monitoring, troubleshooting, and resolving production issues.

Basic Qualifications

• Experience with one or more of the following: Cloud platforms (preferably AWS), Database systems (SQL and NoSQL), Contributing to open‑source projects, Version control systems, Debugging and troubleshooting complex systems
• Demonstrated ability to learn and adapt to new technologies quickly
• Demonstrated ownership and initiative in seeing work through from design to operation
