Location: Houston, Texas (Remote)
Role Overview
We are seeking a senior Identity, Application, and Integration Migration Engineer for a large-scale application migration and separation initiative. This hands-on technical role requires an expert who can validate application behavior, uncover undocumented dependencies, and proactively mitigate migration risks. The ideal candidate has personally experienced large-scale migrations and understands how to ensure business-critical applications continue functioning throughout complex cutover events.
Key Responsibilities
- Support the migration of enterprise applications into diverse target environments, including SaaS, Microsoft 365, Entra ID, and hybrid identity platforms.
- Validate authentication, authorization, and access control models before migration to ensure seamless user access post-cutover.
- Assess and troubleshoot SSO integrations, identity platform configurations, MFA implementations, and certificate-based authentication.
- Map application dependencies and integration points, verifying that applications can communicate with required systems after migration.
- Identify undocumented integrations, authentication dependencies, and certificate requirements that are not captured in architecture diagrams or migration plans.
- Review migration strategies and challenge assumptions when technical plans do not align with the actual environment.
- Work directly with application owners, infrastructure teams, and security teams to resolve migration issues before they impact production.
- Actively participate in cutover bridges and war room activities, providing hands-on troubleshooting for access, identity, and integration-related issues.
- Support post-migration stabilization, resolve deferred issues, and document recurring gaps to improve future migration efforts.
Required Qualifications
Experience:- 8+ years of experience in identity engineering, application engineering, or application migration roles.
- Multiple enterprise application migration and cutover projects in complex, and sometimes poorly documented, environments.
- Proven experience supporting production cutovers, war rooms, and high-pressure migration events.
Technical Skills:- Strong knowledge of Microsoft Entra ID (Azure AD), Active Directory, SSO technologies, and authentication/authorization frameworks.
- Deep experience with MFA platforms, certificate management (PKI), Microsoft 365, and third-party application integrations.
- Expertise in troubleshooting and root-cause analysis across networking, infrastructure, identity, and application dependencies.
- Experience supporting SaaS migrations and tenant-to-tenant migration efforts.
Preferred Qualifications
- Experience with GCC and GCC High environments.
- Experience supporting divestitures, carve-outs, or corporate separation programs.
- Knowledge of networking fundamentals, including DNS, firewall concepts, and infrastructure dependencies.
- Familiarity with FedRAMP environments and security controls.
- Experience supporting coexistence environments during complex migrations.
