Role Overview:

We are looking for an experienced Identity Engineer/Architect to design, operate, and secure enterprise identity services across on-premises and cloud environments.

The role spans ADDS, ADCS, ADFS, Tier 0 infrastructure, and Microsoft Entra ID, including ownership of critical security components.

Role Insights

  • Design, implement, and operate Active Directory (multi-domain / multi-forest), Public Key Infrastructure (ADCS), federation services (ADFS), and hybrid identity with Microsoft Entra ID.
  • Own and enforce Tier 0 security architecture.
  • Lead incident resolution for critical identity outages.
  • Define and improve hardening standards, monitoring and alerting concepts, and patch/lifecycle processes.
  • Analyze and remediate security risks such as misconfigurations and legacy setups.
  • Drive standardization across multiple environments and domains.
  • Support audits (e.g., SOX controls) and compliance requirements.
  • Mentor junior engineers and support knowledge transfer.
  • Participate in on-call rotation for critical services.

What Makes You Unique:

  • Strong hands-on experience with Active Directory (design, troubleshooting, operations).
  • Deep knowledge of Group Policies, DNS, and authentication flows.
  • Solid expertise in ADCS (PKI design, certificate lifecycle, and security).
  • Experience with ADFS or other federation technologies.
  • Knowledge of Microsoft Entra ID (hybrid identity, synchronization, access control).
  • Good understanding of Windows Server internals.
  • Strong networking knowledge (including firewalls and segmentation).
  • Solid understanding of security concepts (Tiering, least privilege, privileged access).
  • Advanced PowerShell skills for automation and scripting.
  • Experience working in complex enterprise environments (multi-domain, multi-country setups).

Nice to Have:

  • Experience with identity providers (e.g., Ping, ADFS alternatives).
  • Familiarity with monitoring tools such as Splunk or SCOM.
  • Experience with cloud and hybrid environments (e.g., Azure).
  • Experience in incident management for critical systems.
  • Familiarity with audit and compliance frameworks (e.g., SOX).
