Software Development Engineers , Amazon Japan Store Tech
Tokyo, JapanFull-timePosted Jul 7, 2026
ApplyDo you want to directly impact how millions of Japanese customers receive their Amazon deliveries? Do you enjoy solving complex optimization problems that reduce cost while preserving — or improving — the customer experience?
Product Family Support Tech (PFST) is a software engineering team within Japan Store Tech that partners with Amazon Japan's retail business to build unique shopping experiences for Japanese customers. We work across the full spectrum of Japan Retail and operate at the intersection of global Amazon technology and locally-driven product innovation.
As an SDE on the PFST team, you will design, build, and operate customer-facing and internal services that power Amazon Japan's retail product experiences. You'll work directly with product teams, contribute to architecture decisions, and be a key voice in how the team solves complex, Japan-unique challenges using global Amazon infrastructure. This is a full-stack role in a broad sense — you'll build backend services, contribute to frontend experiences, and integrate across a large ecosystem of Amazon systems. You'll be expected to operate independently, lead features end-to-end, and raise the bar through code reviews and design feedback.
Key job responsibilities
Your primary responsibilities are designing, developing, testing, deploying, and maintaining distributed software solutions independently. These solutions range across technical stacks and domain, from web applications and backend services, to cloud architecture and machine learning. You will work directly with technical and business teams, locally and worldwide, to understand business problems and design solutions.

- Attend daily standup either in person or remotely to give status updates
- Work on a technical design document to drive consensus between the internal team and stakeholders
