Software Development Engineer, AWS Marketplace Catalog Search

AWS Marketplace helps millions of AWS customers discover evaluate and procure software. The Search team is the intelligence layer behind that discovery; we build the systems that understand what customers are looking for and connect them with the right products solutions and services.

Were a small high-impact team working on search relevancy ranking query intent classification embeddings and ML-powered enrichment. Our systems serve every search query on AWS Marketplace and increasingly power adjacent experiences like Agent Mode console integrations and the broader AWS discovery ecosystem. The problems are genuinely interesting: hybrid search architectures LLM-based content enrichment cross-encoder re-ranking and building evaluation frameworks that let us measure whether were actually getting better.

Were looking for a Software Development Engineer who wants to own hard problems end-to-end. Youll design and build systems that directly impact how customers find software on AWS; from the query understanding layer that classifies intent to the ranking models that decide what shows up first to the evaluation infrastructure that tells us if we got it right.

This isnt a role where youll be handed a spec and asked to implement it. Youll be expected to dig into the data form hypotheses about whats broken or missing propose solutions and ship them. Youll work closely with applied scientists product managers and partner teams building conversational AI and agentic experiences on top of our search platform.

Were a team that values depth over breadth. Wed rather you understand the problem deeply and ship something well-tested than rush to check a box. Code reviews are thorough but collaborative we learn from each other. We run lean which means your work has outsized impact but also that you need to be comfortable with ambiguity and context-switching.

On-call is part of the deal - typically one week every two months. We invest heavily in operational health so pages are rare and when they happen we fix the root cause so it doesnt happen again.

Were a mix of experience levels and backgrounds. Senior engineers mentor newer team members and everyones opinion on architecture and approach carries weight regardless of title. We do our best work when were learning from each other.
