Do you want to directly impact how millions of customers in Japan and across the globe discover, browse, and purchase products on Amazon? Do you enjoy building scalable systems that power seamless shopping experiences across multiple marketplaces? Amazon's International Stores technology teams in Japan — spanning areas like JP Manga, Search, Stores Tech, and more — build and operate the technology that enables customers worldwide to shop across borders. From product discovery and content experiences, to search relevance, checkout, payments, and delivery, our Japan-based engineering teams drive innovation for Japanese customers while contributing to global platform capabilities shared across dozens of marketplaces. The technical challenges are diverse — you'll work on systems that handle massive traffic at low latency, support multi-language and multi-currency experiences, and adapt to the unique regulatory and business requirements of different regions. As an SDE Intern, you'll gain broad exposure across the stack and have the opportunity to own meaningful features end-to-end in a supportive, growth-oriented environment. We also embrace AI as a tool to accelerate how we build and operate software — from AI-assisted coding and automated testing, to intelligent monitoring and issue triage. You'll have the opportunity to both leverage and contribute to AI-driven development practices as part of your day-to-day work. If you're looking to kickstart your engineering career at global scale, solve real customer problems, and work alongside talented engineers in a collaborative international environment, this internship is a great place to start. Key job responsibilities • Collaborate and communicate effectively with experienced cross-disciplinary Amazonians to design, build, and operate innovative products and services that delight our customers, while participating in technical discussions to drive solutions forward. • Design and develop scalable solutions using cloud-native architectures and microservices in a large distributed computing environment. • Participate in code reviews and contribute to technical documentation. • Build and maintain resilient distributed systems that are scalable, fault-tolerant, and cost-effective. • Leverage and contribute to the development of GenAI and AI-powered tools to enhance development productivity while staying current with emerging technologies. • 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. A day in the life As an intern, you will be matched to a manager and a mentor and will have the opportunity to influence the evolution of Amazon technology and lead critical projects early in your career.
