Active Directory Support Engineer

Skills Required:

Security Hardening: Implement and enforce AD security best practices (e.g., securing LDAP channels, disabling legacy protocols like NTLM, and managing privileged accounts).

Migration/Upgrades: Proven experience with AD migrations (e.g., functional level upgrades, domain consolidations) or Windows Server upgrades.

Monitor AD health: Oversee domain controllers, replication, and DNS integration to prevent outages.

Execute production changes: Apply patches, promote domain controllers, and adjust configurations following strict change control processes, primarily scheduled during nights and weekends to minimize business impact.

Troubleshoot platform issues: Resolve replication delays, authentication failures, or Group Policy conflicts using tools like Repadmin or DCdiag.

Support IAM and teams: Provide runbooks, guidance, and hands-on help when IAM or other support teams encounter AD-related issues.

Ensure compliance: Align AD operations with regulatory standards (e.g., internal policies) and audit requirements.

Automate routines: Use PowerShell or scripting to streamline tasks like log analysis or system checks.

Collaborate cross-functionally: Work with cybersecurity, networking, and other teams to support business needs.

Document processes: Maintain technical guides and share knowledge with the IPEM team.

On-call duties: Participate in rotations, including nights and weekends, for urgent incidents.

Required Experience: Active Directory operations (replication, domain controller management, Group Policy infrastructure).

Hands-on experience with AD troubleshooting and monitoring tools.

Scripting proficiency (PowerShell preferred) for automation.

Familiarity with PAM, Zero Trust principles, and CIS benchmarks.

Skills & amp; Mindset:

Adaptable: Shift priorities smoothly in a dynamic setting.

Detail-oriented: Ensure accuracy in system configurations, compliance checks, and following processes and procedures.

Collaborative: Build relationships across teams and communicate clearly.

Proactive: Identify risks and propose solutions."

Salary Range - CA$ 90,000 - CA$ 110,000 Per Year
