Do 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? Amazon Points Platform was originally built for the Japan marketplace and has since expanded globally, delivering cash-back rewards across regions and marketplaces worldwide. It powers programs including Amazon Points, Kindle Unlimited Rewards, Prime Young Adult Cash Back, and Amazon Business Rewards. The technical complexity here is real — every reward transaction requires real-time processing and redemption at checkout, backed by rigorous financial accounting, and each marketplace brings its own business model and regulatory rules. A compact team owns a large fleet of systems, which means every engineer has end-to-end ownership and disproportionate influence. We're also pioneers of AI in how we build and operate software. From design to coding to operations, we use AI agents to turn requirements directly into code changes, autonomously monitor services, and triage issues. AI here isn't a talking point — it's core to how we develop, operate, and iterate. You'll be both a user and a creator of these tools. If you want to solve genuinely hard platform problems at worldwide scale while pioneering AI-native software engineering, this role offers rare depth, real ownership, and a chance to shape how AI-native engineering is done at scale. 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.
