Software Development Engineer II, Amazon Manufacturing Services (AMS)

Do you want to build software that changes how physical things get made? Amazon Manufacturing Services (AMS) runs 135+ machines producing custom parts for over 100 Amazon organizations. We are building the next generation of services and applications that digitize shop floor operations, integrate with enterprise manufacturing platforms, and lay the groundwork for intelligent production scheduling. You will work across the full stack — React applications for operators and planners, event-driven backend services processing manufacturing data in real time, and integration bridges connecting AMS to enterprise ERP, PLM, and MES systems. The team is small, the technical surface is broad, and the users are in the building.Key job responsibilities* Design, build, and operate services on AWS Lambda, DynamoDB, S3, SNS, SQS, and Step Functions using event-sourced, domain-driven architecture patterns* Build React web applications using the Cloudscape Design System for manufacturing operators, planners, and engineers* Integrate AMS services with enterprise platforms through event-based and API-based integration patterns* Design and implement API models, CDK infrastructure, and CI/CD pipelines for new services* Collaborate with senior engineers on system design, code reviews, and architecture decisionsA day in the lifeYour day starts with a standup alongside SDEs, data engineers, and manufacturing stakeholders. You pick up where you left off on a React component that displays real-time resource status for shop floor planners. After lunch, you shift to a backend service, designing a DynamoDB schema for part versioning. A code review comes in from a senior engineer working on an enterprise integration bridge, and you spend time understanding how AMS connects to external manufacturing platforms. Some weeks lean more frontend — building interactive data visualizations or responsive layouts for shop floor devices. Other weeks lean more backend — implementing event-sourced entity patterns or integrating with third-party APIs. The mix depends on the sprint and your strengths.Basic qualifications- 4+ 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- 2+ years of full stack development experience- 2+ years of building production software experience- Experience with full software development life cycle, including coding standards, code reviews, source control management, build processes, testing, and operations- Knowledge of Machine Learning and LLM fundamentals, including transformer architecture, training/inference lifecycles, and optimization techniques- Bachelor's degree or foreign equivalent in Computer Science, Engineering, Mathematics, or a related fieldPreferred qualification - 5+ years of full software development life cycle, including coding standards, code reviews, source control management, build processes, testing, and operations experience- 4+ years of full stack development experience- 1+ years of mathematics optimization such as linear programming and nonlinear optimization experience- 1+ years of machine learning, statistical modeling, data mining, and analytics techniques experience- Experience with Machine Learning and Large Language Model fundamentals, including architecture, training/inference lifecycles, and optimization of model execution- Master's degree in computer science or equivalentAmazon is an equal opportunity employer and does not discriminate on the basis of protected veteran status, disability, or other legally protected status.Our inclusive culture empowers Amazonians to deliver the best results for our customers.
