Position Summary:

We are seeking a Senior Engineer Identity Infrastructure & MA&D to serve as a technical leader responsible for the design integration and optimization of Cencoras identity platform across on-premises Active Directory Microsoft Entra ID (formerly Azure AD) and related authentication/authorization services. This role is central to our corporate development strategy: you will lead the identity workstream for acquisitions (onboarding users devices and applications from acquired entities into Cencoras identity ecosystem) and divestitures (cleanly separating identity services and severing trust relationships). Identity is the foundational layer that gates access to every system application and resource making this one of the most critical and complex workstreams in any deal.

The ideal candidate combines deep Active Directory and Entra expertise with the structured security-conscious mindset required to execute identity transitions without disrupting user productivity or compromising the security posture of either organization.

Primary Focus

Advanced identity infrastructure design MA&D identity integration/separation authentication and access management complex troubleshooting and cross-functional technical leadership.

Key Responsibilities:

Identity Infrastructure Engineering

• Design and maintain Cencoras enterprise identity architecture spanning on-premises Active Directory Domain Services (AD DS) Microsoft Entra ID Entra Connect (formerly Azure AD Connect) and Entra Domain Services ensuring a resilient well-governed and scalable identity platform.

• Own the AD forest and domain topology manage domain controllers sites and services replication topology FSMO roles Group Policy (GPO) architecture and OU structure across a multi-site enterprise environment.

• Administer and optimize Microsoft Entra ID manage tenant configuration application registrations enterprise app SSO integrations (SAML OIDC WS-Fed) Entra Connect sync rules and hybrid identity topologies.

• Manage multi-factor authentication (MFA) and Conditional Access design and enforce Entra MFA policies Conditional Access frameworks authentication strengths and risk-based access controls aligned with zero-trust principles.

• Oversee certificate services and PKI where applicable AD Certificate Services (AD CS) certificate templates auto-enrollment and certificate-based authentication.

• Perform advanced troubleshooting of complex identity issues Kerberos/NTLM authentication failures AD replication conflicts Entra Connect sync errors token issuance problems Conditional Access policy conflicts and hybrid join issues.

• Drive identity automation leverage PowerShell Microsoft Graph API and automation platforms to streamline user lifecycle management group management and identity governance tasks.

• Document and maintain identity architecture diagrams trust relationship maps Entra Connect topology GPO standards and operational run-books.

Mergers Acquisitions & Divestitures (MA&D)

• Lead the identity workstream for each MA&D event end-to-end from due diligence through Day 1 access enablement to full identity consolidation or separation and steady-state hand-off.

Acquisition Integration

• Conduct identity discovery and assessment of target company environments: inventory AD forests/domains domain controllers Entra tenants federation services (AD FS PingFederate Okta etc.) MFA solutions PAM tools and SSO-integrated applications.

• Develop identity integration blueprints that define the path from Day 0 (deal close) to full consolidation including interim coexistence strategies trust relationships Entra B2B/cross-tenant access GAL synchronization and phased user migration plans.

• Architect and execute AD consolidation design inter-forest trust relationships plan and execute domain migrations (ADMT or equivalent) migrate user accounts computer objects group memberships SID history and GPOs into the Cencora AD environment.

• Plan and execute Entra ID tenant consolidation migrate cloud identities application registrations Conditional Access policies and MFA registrations from the acquired tenant into Cencoras Entra tenant using cross-tenant migration tools and Microsoft Graph.

• Manage Entra Connect reconfiguration transition sync scope filtering rules and hybrid identity topology as domains and OUs are consolidated.

• Coordinate user MFA re-enrollment or migration ensure acquired users are seamlessly onboarded to Cencoras Entra MFA policies with minimal friction planning for authentication method registration Authenticator app rollout and fallback methods.

• Enable Day 1 access ensure acquired employees have functional credentials email and access to critical systems from the moment the deal closes even before full consolidation (e.g. via Entra B2B external identities or temporary trust configurations).

Divestiture Carve-Out

• Architect identity separation plans that cleanly extract divested users groups service accounts and computer objects from Cencoras AD and Entra environments into a new or target-company identity platform.

• Stand up greenfield identity infrastructure where needed new AD forests/domains Entra tenants Entra Connect instances MFA policies and Conditional Access baselines for the divested entity.

• Manage coexistence during TSA periods design interim trust relationships cross-tenant access policies and shared authentication mechanisms that allow continued access to shared resources until the Transition Services Agreement expires.

• Plan and execute credential cutover coordinate the transition of user identities passwords (or forced resets) MFA methods and device registrations to the divested entitys identity platform with minimal disruption.

• Sever trust relationships and remove residual access methodically decommission forest/domain trusts Entra B2B relationships cross-tenant configurations and stale objects post-TSA to eliminate security exposure.

Leadership & Collaboration

• Collaborate cross-functionally with Security Network Messaging/M365 Application Endpoint and GRC teams to ensure identity changes are coordinated with dependent systems email migration device management (Intune) application SSO cutover and security tooling.

• Partner with Project Management and Corporate Development to align identity milestones with broader deal timelines legal close dates budgets and business commitments.

• Coordinate with the acquired/divested companys IT staff to gather requirements validate discoveries and execute joint cutover activities.

• Develop and enforce identity standards and policies ensuring compliance with Cencora security and regulatory requirements (e.g. HIPAA SOX DEA) and zero-trust principles.

• Mentor and guide junior identity and systems engineers; serve as the technical escalation point for complex identity incidents.

• Build repeatable MA&D identity playbooks standardize discovery templates migration checklists cutover run-books and rollback procedures to accelerate and de-risk future deals.

Experience skillset & Educational requirements:

• Bachelors degree or technical institute degree/certificate in a relevant field or equivalent work experience.

• Typically requires 8 or more years of relevant IT work experience.

• Experience leading technical teams preferred

• Relevant certification is required.

• Demonstrates in-depth knowledge of a broad range of hardware and software products.
