OneOncology's IT Operations team is the engine that keeps the infrastructure, identity, and management platform running for every OneOncology practice. IT Operations owns proactive monitoring, patching, backup, identity governance, network engineering, and Tier 3 escalation across the enterprise. 

The Systems Engineer III is a principal engineer setting technical direction across the systems domain — server infrastructure, virtualization, backup, cloud, identity, and Citrix end-user computing (EUC). The role acts as architect of the Citrix Virtual Apps and Desktops environment and final technical authority for complex systems operational decisions and long-horizon planning. The ideal candidate brings enterprise systems architecture skills, deep expertise across multiple systems specialties, and strong executive-facing communication.

• Design and drive automation of systems provisioning, patching, and configuration using PowerShell and infrastructure-as-code approaches. 

• Define systems hardening, backup, and disaster recovery standards, including DR validation testing, in support of HIPAA and HITRUST requirements. 

• Represent OO IT in strategic vendor discussions for systems platforms and cloud services. 

• Establish and enforce systems standards across all managed practices. 

• Mentor the systems engineering bench across Administrators and Engineers. 

• Advise IT leadership on long-term systems technology direction and roadmap. 

• Partner with Projects on precedent-setting systems deliveries and standards evolution. 

• Coordinate closely with the Network Engineer III on integrated solutions spanning systems and network.
