Software Development Engineer II, SoR Fulfillment

Description

Build the automation infrastructure that powers AWS's global expansion into new markets. Join the SoR Requirement Fulfillment (SuRF) team within AWS Commerce Platform (CP) to design and develop sophisticated pipeline orchestration systems, entity management services, and validation frameworks that enable AWS to launch new Sellers of Record across 30+ countries, from entity creation and configuration deployment to automated CX validation across billing, invoicing, tax, and payments systems.

As a Software Development Engineer on this team, you'll design, build, and operate distributed services and deployment pipelines that orchestrate the automated delivery of SoR configurations across multiple CP services, manage the lifecycle of Commerce Platform entities (Cloud Sellers, Branches, Marketplace Sellers, and more), and validate SoR features against customer experience requirements. Your work will directly impact how quickly AWS can expand its local presence globally while ensuring billing accuracy, tax compliance, and operational excellence at scale.

Design and implement production-quality distributed services for the SoR Fulfillment platform, including entity management services, pipeline orchestration systems, and configuration deployment frameworks, ensuring reliability, security, and compliance across multiple AWS partitions.

Develop and enhance the Entity Suite services that store and manage CP entities (Cloud Sellers, Branches, MP Sellers, Marketplaces, JWCC‑ATAT Entities), supporting the full lifecycle from creation through configuration and validation.

Build and maintain SoR Pipeline infrastructure that automatically takes configuration values from the requirements repository, triggers deployments to CP services, and executes behavior validation tests asynchronously for each requirement.

Lead large, multifaceted projects spanning multiple engineers and cross‑functional teams (Tax, Invoicing, Payments, Accounting, Legal), driving technical decisions from design through production deployment.

Participate in engineering design reviews and architecture discussions, contributing both technical expertise and domain knowledge of SoR launch processes to shape product direction.

Resolve complex distributed systems and pipeline orchestration issues by identifying root causes and implementing systematic improvements that enhance software quality and deployment reliability.

Build and integrate automated validation frameworks using Gherkin‑based BDD that enable shift‑left testing, automated CX validation, and requirement‑level test execution through the SoR Pipeline.

Develop and maintain the CRUX analyzer and Code Scanner tools that enforce automation standards via code analysis, ensuring configuration changes follow established patterns and reducing manual intervention.

Contribute to the evolution of the SoR acceleration platform architecture, balancing innovation with operational excellence as the system scales to support 10+ SoR launches per year.
