Team Insight:CDN Site Reliability Engineering combines software and network engineering with system operations to build and run large-scale, massively distributed infrastructure. Our Edge SREs ensure infrastructure services are reliable, fault-tolerant, efficiently scalable and cost-effective. We dive deep into the stack, including network, OS, and applications, to quickly resolve complex functional and performance issues. In order to enhance collaboration and cross-functional partnerships, among other things, at this time, our organization follows a hybrid work schedule that requires employees to work in the office 3 days a week, or as directed by their manager/department. We regularly review our hybrid work model, and the specific requirements may change at any time.
