About The Position
The Systems Engineer Senior plays a critical role in architecting, deploying, and managing enterprise infrastructure across cloud, compute, storage, load balancing, and datacenter environments. As a senior member of the Cloud, Infrastructure, and Platform Services (CIPS) team, this position ensures the reliability, security, and performance of both on-premises and cloud-based services.

This role requires a deep understanding of virtual and physical compute systems, SAN and NAS storage, enterprise backup and disaster recovery, application delivery and load balancing platforms, and modern public cloud services.
