Software Engineers perform development work across the technology stack (both front-end/back-end expertise). They are versatile in how they can add value, demonstrating the ability to manage the completion of projects that involve databases, backend services, or the development of front-end applications. They should be able to demonstrate a strong understanding of emerging technologies to support the development of new solutions. Software Engineers understand the full technology stack and underlying applications, services, and databases in order to ensure optimal performance.
The eCommerce Website Development Software Engineer is responsible for the overall design of a product and the definition of the technical blueprints/designs to fulfill specific requirements. They provide technical expertise to Product Managers and the Development Pods as they reconcile the users' needs and requirements with what the engineers have determined to be doable within the given (engineering) constraints. They work closely with Solution Architects, Product Managers, POD teams, and Product Owners to support the implementation and delivery of new and/or enhanced capabilities. Lastly, they are responsible for defining non-functional requirements (e.g., performance, resilience, etc.) to ensure the scalability and reliability of a given product within a complex ecosystem.
If you want to be a part of one of the worldwide BEST companies “to work for”, simply apply and let your career be reimagined.
