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. The Systems Engineer Senior will collaborate closely with architects, cybersecurity professionals, and development teams to integrate systems and services while maintaining compliance, automation, and operational excellence.
