  • 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.
  • Ensure systems adhere to stringent security requirements (e.g., STIG/RMF/NIST), especially within federal or classified environments.

  • Bachelor’s in computer science, Information Technology, or related field — or equivalent practical experience.
  • 10+ years Server administration

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

We Value (Differentiators)

  • 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.
