• Maintain a HIPAA-aware security posture including access controls, encryption standards, audit logging, and vulnerability management
• Manage virtual desktop infrastructure for internal teams and contractors, including provisioning, imaging, and access control
• Support hybrid and multi-cloud infrastructure, including hands-on Azure work alongside our primary AWS environment
