Costco IT is a dynamic, fast-paced environment, working through exciting transformation efforts
We are building the next generation retail environment where you will be surrounded by dedicated and highly professional employees.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.Software engineers in this team are involved in architecting, designing and building of distributed software systems and products which will be deployed in the cloud (GCP/Azure)
The software engineers in the performance engineering teams are also expected to analyze at scale issues, provide insights and hypotheses for issues at scale and provide guidance to others. 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.ROLE Develops the conceptual systems architecture design and the supporting technologies needed to enable new and/or enhanced functionality within a given product/application, applying principles that promote availability, reusability, interoperability and security into the design framework.
