The Merchandising Tech team builds the technology that helps customers discover new, popular, and relevant products across Amazon worldwide. We are building the next generation of AI-driven systems that improve how millions of customers discover products across Amazon’s shopping experiences. By combining large language models (LLMs), vision-language models (VLMs), and Amazon’s first-party data on shopper behavior and conversion patterns, we design systems that assist in generating, selecting, and optimizing marketing and merchandising experiences at scale. We train, evaluate, and operate models end-to-end in-house, from data pipelines to model lifecycle management and large-scale inference, ensuring that AI capabilities are tightly integrated into our distributed systems and measurable in customer and business impact.

We are looking for a Senior Software Engineer who will lead the design and evolution of systems that generate, assemble, and optimize creative assets at scale across regions and business surfaces. You will build systems that automatically produce and adapt images, text, layouts, and multimodal content used across merchandising surfaces. These systems must balance creative flexibility, brand constraints, performance signals, and operational reliability. These platforms support high-traffic global events across Amazon marketplaces worldwide, requiring predictable scalability and operational resilience under peak conditions.

As a Senior Software Engineer, you are a recognized technical leader who drives the engineering strategy, mentors team members, and partners with cross-functional teams to deliver complex end-to-end AI solutions. Your work focuses on architecting and implementing robust systems in ambiguous problem areas where both the business problem and solution approach need to be defined. This role requires end-to-end ownership across model integration, distributed services, and measurement frameworks. You will identify structural bottlenecks in AI system evolution and design architectural boundaries that allow model development, experimentation, and application services to evolve independently without compromising reliability or scalability.

You will define architectural patterns for creative automation, establish engineering standards for AI-driven asset generation, and ensure that experimentation, ranking integration, and monitoring are designed as first-class system capabilities. You will collaborate closely with applied scientists, product managers, and downstream platform teams to translate model capabilities into reliable, scalable creative services used globally. This role offers the opportunity to take cross-organizational technical ownership, drive highly visible initiatives, and influence how GenAI systems are designed and adopted across multiple teams.
