We are looking for a passionate engineer to work on the development of Tier-1 services for Alexa Cloud that power customer-facing experiences across domains — from audio and video to smart home, shopping, and beyond.

The team handles tens of billions of transactions per day. We are increasingly an AI-first team — embedding intelligence into our services and our development lifecycle. This is a highly visible role to get in at the inception phase, build new AI-enhanced features, and operate a Tier-1 Cloud Service. The ideal candidate is excited about the incredible opportunity that Alexa and Cloud represent, and is passionate about delivering high-quality services in a hyper-growth environment where AI is a core accelerator.

• 5+ years of leading design or architecture (design patterns, reliability and scaling) of new and existing systems experience
• Experience as a mentor, tech lead or leading an engineering team

Preferred Qualifications

• 5+ years of full software development life cycle, including coding standards, code reviews, source control management, build processes, testing, and operations experience
