• Automate infrastructure deployment, configuration, and maintenance at scale using PowerShell and other scripting languages (e.g., Python), focusing on IaC (Infrastructure as Code) principles.
• Architect, deploy, and manage Public Key Infrastructure (PKI) solutions and oversee certificate/TLS lifecycle management across the enterprise.
• Perform complex, end‑to‑end troubleshooting of infrastructure issues, covering networking (TCP/IP, routing, load balancing), identity (Kerberos/LDAP), and application integration.
• Document runbooks, standard operating procedures (SOPs), and change procedures; participate in scheduled change windows and on‑call rotation.
• Contribute to cloud strategy and migration efforts by providing technical expertise for AWS and/or Azure platform integration.

• Experience with VDI deployments.
• Hands‑on experience with SolarWinds for enterprise IT infrastructure and environment monitoring.
• Experience with Active Directory in production environments.

Preferred Qualifications

• Deep understanding of networking fundamentals (TCP/IP, DNS, DHCP, routing protocols) and experience with load balancers (e.g., F5/NetScaler).
• Proven experience in designing and managing PKI and handling the entire certificate lifecycle.
• Excellent written and verbal communication skills, with a proven ability to document complex systems.
• Background in AWS and/or Azure infrastructure, services, and best practices.
• Familiarity with security compliance frameworks and tools for federal/classified environments (STIG, RMF, NIST).
• Experience with enterprise other monitoring solutions (e.g., SCOM, Splunk, health sets) is a plus.
• Exposure to Microsoft 365 (M365) technologies, including Hybrid/M365 touchpoints (e.g., Modern Auth, EOP/Defender).

Benefits

• Traditional and HSA‑eligible medical insurance plans
