Senior Systems Engineer
About The Position
The Senior Systems Engineer is a senior individual contributor and technical anchor on a small Systems and Network team, responsible for core infrastructure in a large, regulated hybrid environment spanning Windows and Linux servers and endpoints, on-premises VMware, and Azure. The role owns on-premises server platforms, Active Directory and identity services, enterprise patching, and the enterprise backup platform, along with the systems-side IT general controls that depend on them. It also supports Windows and Linux workloads hosted in Azure according to standards set by the cloud platform team, and partners with Information Security on server-estate remediation while Information Security retains ownership of its security tooling, vulnerability-management program, and audit findings. The position focuses on operating and modernizing infrastructure, automating repetitive work, expanding coverage across identity and core platforms, and reducing the infrastructure improvement backlog. It also supports Microsoft 365, email security, managed file transfer, and—in backup capacity—enterprise switching, firewall, and SD-WAN. The role is based at Corporate Headquarters in Greenville, South Carolina, with hybrid flexibility, shared on-call rotation, and occasional travel as needed.
