About The Position

Chewy is seeking a Software Engineer III to lead the development and scaling of highly available, distributed software systems that power critical business capabilities and customer experiences! As a high-performing backend engineer, you will drive the architecture, design, and implementation of scalable services, APIs, and event-driven platforms that support complex operational workflows and high-volume transactions. In this role, you will collaborate closely with engineering and business partners from multiple functions. You will solve challenging technical problems, improve system reliability and performance, and enable long-term platform scalability. This senior technical leadership role offers broad exposure across multiple organizations. It provides the opportunity to influence engineering strategy, establish guidelines, mentor engineers, and develop a high-performing, collaborative engineering culture. The ideal candidate holds a Bachelor’s degree in Computer Science or a related field, or equivalent industry experience. You excel at leading engineering teams and driving backend architecture and system design for scalable, distributed platforms. Our systems leverage loosely coupled services, real-time event processing, vendor integrations, CQRS/event-driven architecture, and modern CI/CD practices. You will work with technologies including Java, JavaScript, Node.js, GraphQL, DynamoDB, SNS/SQS, AWS ECS/Fargate, Kubernetes, Kafka, and AWS Lambda to build and scale critical platform capabilities. In this role, you will lead the development and deployment of scalable services, applications, and automation frameworks that improve operational efficiency and business workflows. You also bring hands-on experience using AI coding assistants such as GitHub Copilot, Cursor, or Claude within real engineering workflows, with a practical understanding of where they accelerate delivery and where human judgment remains critical.
