  • Demonstrated expertise in Linux/Unix and Windows server environments, including command-line administration and system-level operations.
  • Experience with infrastructure-as-code and automation frameworks such as Terraform, Ansible, Chef, or Puppet for managing certificate deployments at scale.
  • Knowledge of monitoring and alerting platforms to implement certificate status tracking, expiration monitoring, and incident notification systems.
  • Perform routine CA maintenance: database backups, CA certificate renewal, CRL/AIA rollover planning, and root/subordinate CA key ceremonies as needed.
  • Troubleshoot ADCS-related issues — enrollment failures, template permission issues, autoenrollment failures, SPN/Kerberos-related errors (e.g., WSMAN SPN issues for remote enrollment/orchestration).
  • Excellent organizational, communication, and problem-solving abilities with strong attention to detail, ability to document procedures clearly, and communicate technical concepts effectively.
