Diagnose and resolve replication, consistency, and LDAP edge cases, and ensure safe write paths with idempotency and integrity guarantees.
Minimum Requirements
Deep hands-on expertise with Active Directory internals: schema, replication metadata, directory access (LDAP, DirSync, USN cookies), object lifecycle, identity continuity, Group Policy, and AD-integrated DNS.
Experience with safe write operations in AD: modify, ModifyDN, and object creation with conflict handling.
Work Experience Required: Not explicitly mentioned in the JD.

Ideal Candidate Profile
Experienced systems engineer with deep understanding of Active Directory internals, replication, and identity continuity mechanisms.
Comfortable debugging complex AD replication and LDAP issues, with experience handling multi-domain/multi-forest environments preferred.
Technical proficiency in C/C++, C#, and Go with background in building backup, disaster recovery, or migration tooling for AD.
