Senior IAM Architect - Microsoft Entra Identity & Access Management - Dallas, TX (Hybrid)

[Sid K]

Hi Folks,

My client is looking for Senior IAM Architect - Microsoft Entra Identity & Access Management for 6 Month Contract role based in Dallas, TX (Hybrid)

Position: Senior IAM Architect - Microsoft Entra Identity & Access Management

Location:  Dallas, TX (Hybrid)

Duration: 6 Month Contract

 

Key Responsibilities

Define enterprise Microsoft Entra IAM security architecture, standards, reference architectures, design patterns, and engineering guardrails.

Architect secure identity solutions across cloud, hybrid, multi-cloud, SaaS, and on-premises environments.

Develop and implement an identity-centric Zero Trust architecture, emphasizing continuous verification, least privilege, strong authentication, and risk-based access.

Design enterprise Conditional Access strategies covering users, administrators, workloads, applications, devices, authentication strength, and risk.

Architect phishing-resistant and passwordless authentication solutions using FIDO2/passkeys, Windows Hello for Business, certificate-based authentication, and other supported authentication methods.

Design and govern Privileged Identity Management (PIM) and privileged-access models to minimize standing administrative privileges and enforce just-in-time access.

Establish security architecture for workload identities, managed identities, service principals, application registrations, API permissions, and secrets/certificate management.

Architect secure application authentication and authorization using OAuth 2.0, OpenID Connect, SAML 2.0, SCIM, Microsoft Graph, and modern authentication patterns.

Design Entra ID Governance capabilities, including entitlement management, access reviews, lifecycle workflows, separation of duties, and automated identity lifecycle controls.

Define security architecture for joiner, mover, and leaver (JML) processes and ensure timely provisioning, modification, and removal of access.

Design and review hybrid identity security, including Active Directory integration, Entra Connect/Cloud Sync, authentication flows, and protection of privileged identity paths.

Lead IAM threat modeling and security architecture reviews for new applications, platforms, cloud services, and major technology initiatives.

Identify identity-related attack paths, excessive privileges, legacy authentication dependencies, insecure application permissions, and other IAM security risks.

Design controls for detecting and responding to identity compromise, credential theft, token abuse, risky sign-ins, privilege escalation, and unauthorized access.

Define identity logging, monitoring, and alerting requirements and integrate Entra telemetry with SIEM/SOC and security operations processes.

Provide architecture and engineering leadership during complex identity security incidents and root-cause investigations.

Develop automation using Microsoft Graph API, PowerShell, REST APIs, and infrastructure-as-code/policy-as-code approaches to improve security consistency and reduce manual administration.

Lead IAM modernization, tenant consolidation, authentication modernization, application migration, and security-hardening initiatives.

Evaluate new Microsoft identity capabilities and recommend adoption based on security benefits, operational impact, architectural fit, and organizational risk.

Mentor IAM engineers and architects and provide technical leadership across IAM/security engineering teams.

Security Architecture Focus

The successful candidate should demonstrate deep expertise in designing controls that protect identities as a primary enterprise security boundary. Key areas should include:

Zero Trust identity architecture

Least privilege and Just-in-Time/Just-Enough Administration

Conditional Access architecture and policy design

Phishing-resistant MFA and authentication strength

Passwordless authentication

Privileged Access Management / PIM

Identity Protection and risk-based access

Workload identity and service principal security

OAuth consent and application permission governance

Token and session security

Identity Governance and access certification

RBAC and authorization architecture

Administrative tiering and privileged account separation

Break-glass/emergency access architecture

Legacy authentication elimination

Hybrid identity and Active Directory security

Identity threat detection and incident response

Identity security posture management

Separation of duties and toxic-access controls

 

Required Technical Skills

Deep expertise with Microsoft Entra ID, including Conditional Access, PIM, Identity Protection, ID Governance, Enterprise Applications, App Registrations, workload identities, authentication methods, Microsoft Graph, and hybrid identity.

Strong knowledge of Active Directory, Entra Connect/Cloud Sync, Microsoft 365 identity integration, Azure RBAC, and the relationship between cloud and on-premises identity security.

Advanced understanding of identity protocols and standards including OAuth 2.0, OpenID Connect, SAML 2.0, SCIM, Kerberos, LDAP, and modern authentication.

Strong automation capabilities using PowerShell and Microsoft Graph API, with experience applying automation to identity provisioning, security controls, policy deployment, reporting, and governance.

Strong understanding of identity-related security threats, including credential theft, token theft/replay, MFA bypass techniques, consent phishing, privilege escalation, compromised service principals, excessive application permissions, and lateral movement involving identity systems.

Architecture & Leadership Expectations

This is not primarily an Entra administration role. The Senior Architect / Engineer is expected to:

Translate business, cybersecurity, regulatory, and risk requirements into scalable IAM architectures.

Make and defend complex identity security architecture decisions.

Balance security requirements against user experience, operational complexity, resilience, and business requirements.

Establish reusable enterprise architecture patterns rather than designing one-off solutions.

Conduct architecture and security reviews and identify material IAM risks.

Provide technical leadership for complex implementations and security remediation.

Influence application, cloud, infrastructure, and cybersecurity architecture beyond the IAM organization.

Communicate identity risks and architectural decisions effectively to both technical teams and senior stakeholders.

Remain technically hands-on enough to validate designs, develop proofs of concept, troubleshoot complex problems, and guide engineering teams through implementation.

 

Experience

Typically 10+ years of experience in Identity & Access Management, cybersecurity, infrastructure security, or related disciplines, including substantial experience designing Microsoft identity solutions.

Candidates should have demonstrated experience architecting IAM solutions in large, complex enterprise environments, preferably including hybrid identity, large application portfolios, privileged-access environments, and regulated or security-sensitive workloads.

Experience leading major identity transformation programs—such as Zero Trust adoption, MFA/passwordless transformation, Conditional Access modernization, Active Directory/Entra modernization, privileged-access transformation, or migration from legacy IAM/federation platforms—is highly desirable.

Thanks
