Principal Software Engineer, Prime Video Commerce Tech

When a customer opens Prime Video anywhere in the world - on a Fire TV in Mumbai, a phone in Tokyo, a browser in Berlin - a commerce system determines if they are entitled to watch a content, what it costs, Basic qualifications: • 12+ years of software development experience with deep expertise in distributed systems • Track record of leading architecture transformations across multiple teams and services (not just designing — driving adoption) • Experience operating systems at large scale (millions of TPS) with high availability • Demonstrated ability to influence without authority across organizational boundaries • Hands-on practitioner: you write code, review designs, and prototype — not just govern from a distance • Experience with service-oriented architecture evolution (decomposition, interface harmonization, platform building) Preferred: • Commerce, payments, or subscription systems at global scale (multi-currency, multi-territory, regulatory complexity) • Hands-on experience with AI/GenAI — both as a development practice (AI-native SDLC) and as a system capability (agent-callable services, intelligent decision making) • Experience with resiliency engineering (graceful degradation, blast-radius isolation, chaos testing) • Track record of mentoring senior engineers toward Principal-level scope and judgment • Rapid experimentation: building simulation/forecasting frameworks or ML-driven recommendation systems • International expansion experience (local payment methods, regulatory compliance, market-specific adaptation) Our inclusive culture empowers Amazonians to deliver the best results for our customers.
