Job Description:

ENTERPRISE ACTIVE DIRECTORY & IDENTITY ENGINEER

We are seeking an experienced Enterprise Active Directory & Identity Engineer who understands that enterprise identity involves much more than managing users and computers. This role requires deep knowledge of how domains, forests, organizational units, Group Policy, trusts, authentication, DNS, and replication work together in a complex environment.

You will engineer, troubleshoot, maintain, and modernize identity services across a large enterprise infrastructure. The position supports established on-premises Active Directory environments while advancing the adoption of Microsoft Entra ID and Azure-based identity capabilities.

MEANINGFUL WORK AND PERSONAL IMPACT

Responsibilities

•Engineer and improve complex Active Directory environments spanning multiple domains, forests, organizational units, and interconnected systems.
•Analyze and manage Group Policy design, inheritance, precedence, filtering, enforcement, and enterprise-wide impact.
•Troubleshoot Windows authentication, domain connectivity, replication, DNS integration, policy application, and directory-related issues.
•Investigate how identity configurations affect operating systems, applications, infrastructure services, security controls, and other enterprise capabilities.
•Support domain trusts, forest relationships, cross-domain authentication, and directory dependencies.
•Help integrate and evolve traditional Active Directory services with Microsoft Entra ID and Azure identity capabilities.
•Identify configuration weaknesses, policy inconsistencies, security gaps, and opportunities to improve identity administration.
•Use PowerShell and related tools to analyze configurations, automate administrative tasks, validate policy enforcement, and improve operational efficiency.
•Collaborate with engineering teams across systems, applications, virtualization, networking, cloud, and cybersecurity.

Why This Role Is Different

This is not a routine account administration position. Active Directory is a foundational service supporting an enterprise mission across 28 IT engineering disciplines . Identity changes can affect endpoints, servers, applications, virtual environments, authentication, security controls, and enterprise connectivity.

You will troubleshoot issues that cross technology boundaries, evaluate dependencies before implementing changes, and help shape the next generation of enterprise identity services. The role offers hands-on work with both established on-premises infrastructure and emerging cloud identity technologies.

What Success Looks Like

You understand how identity operates across the enterprise—not just how to administer individual components. You can trace Group Policy behavior through organizational units, inheritance, filtering, and domain configuration. You can investigate authentication failures, replication issues, trust relationships, and directory dependencies using evidence rather than guesswork.

You anticipate how changes may affect dependent services, preserve the reliability and security of the existing environment, and help modernize identity capabilities. Most importantly, you become a trusted engineer for solving complex identity challenges that affect the enterprise as a whole.

We value critical thinking, independence, continuous learning, cross-team collaboration, and a healthy balance between exceptional performance and family life. If you understand that enterprise identity is the foundation connecting technology—and want to help engineer what comes next—we want to hear from you.

Understand the Directory. Control the Policy. Secure the Identity. Engineer the Enterprise.
