Software Dev Engineer II, Amazon Catalog

Job :  |  Services LLC

What if the system you built today was used by hundreds of millions of people -- not hypothetically, but literally?

Amazon Selection & Catalog Systems (ASCS) is the engine behind the world's largest product catalog. Billions of products. Hundreds of millions of real-time updates daily. Every price change, every new listing, every inventory shift, our systems make it happen, 24/7/365, at a scale where textbook solutions simply don't apply.

We're hiring a Software Development Engineer (L5) to join our Selection & Curation Systems team in Seattle, and this isn't your typical SDE role.

• Ensuring product identity and traceability at global scale.
• Processing and normalizing standardized product data from trading partners worldwide.
• Extracting structured data from unstructured content using LLMs
• Automatic classification of items and data at catalog scale
• Big data visualization and analytics pipelines
• Massively distributed systems that push the limits of scale and performance

If you've ever wanted to work on problems where the answer doesn't exist yet and build it, this is that opportunity.

• You have strong technical design instincts and can architect systems that work reliably at extreme scale
• You're comfortable leading across team boundaries — aligning with business owners, senior developers, and principals
• You're energized by ambiguity and greenfield work, not intimidated by it
• You ship, you learn, you iterate

• Direct impact on hundreds of millions of customers and sellers worldwide, your work shows up in the shopping experience, every day
• Ground floor of a new technology stack with a clear scaling trajectory
• Cutting-edge problem space: LLMs, distributed systems, big data, applied to real products at real scale
• A team that's fast-moving, collaborative, and genuinely fun to work with

As a software development engineer on this team, you will play a pivotal role in the following:

• Work with the team to help drive business decisions
• Design, implement, test, deploy and maintain innovative software solutions to drive services optimizations, cost, and security.
• Use software engineering best practices to ensure a high standard of quality for all of the team deliverables
• Write high quality distributed system software
• Work in an agile, startup-like development environment, where you are always working on the most important stuff.

• 3+ years of non-internship professional software development experience
• 2+ years of non-internship design or architecture (design patterns, reliability and scaling) of new and existing systems experience
• Experience programming with at least one software programming language

• 3+ years of full software development life cycle, including coding standards, code reviews, source control management, build processes, testing, and operations experience
• Bachelor's degree in computer science or equivalent
