• Design and implement scalable, cloud-native distributed systems using serverless architectures, event-driven patterns, and microservices on AWS to support EU Prime customer engagement across marketing channels
• Cross functional collaboration with Sciences, Data experts, business teams, Product leaders and core stores platform teams to integrate GenAI/LLM technologies and ML pipelines into production systems that drive personalized customer experiences at scale
• Participate actively in the full software development lifecycle including code reviews, architecture reviews, testing, deployment, and operational excellence activities while mentoring team members on high-quality engineering practices
• Drive technical decisions and design solutions for ambiguous, cross-functional initiatives that balance new feature development with system reliability, performance optimization, and maintainability
• Identify and resolve root causes of operational issues while continuously improving team operations, documentation, and processes to reduce single-threaded dependencies and build team resilience

A day in the life
You'll design and ship features that leverage GenAI-powered services and modern AWS architectures, collaborating closely with scientists to translate ML models into reliable production systems. Your day balances building innovative capabilities with maintaining operational excellence — participating in architecture and code reviews, using AI-assisted development tools to accelerate delivery, and ensuring systems perform reliably at scale. You'll work across teams to shape technical direction while staying current with emerging technologies like GenAI and ML to solve real customer problems. Every engineer has autonomy to shape how Amazon reaches and engages customers wherever they are — on Amazon and beyond.
