A large public sector organisation operates a Microsoft Identity Manager (MIM) platform on-premise and is preparing a phased migration to Microsoft Entra ID Governance. This role exists to maintain and evolve the current MIM estate and to translate existing workflows and lifecycle rules into a future Entra-based governance model, using .NET development, PowerShell scripting and Visual Studio for integrations and custom logic.
The mission
The immediate focus is operational ownership of the on-prem MIM installation: keeping workflows, connectors and lifecycle rules stable while implementing incremental improvements to provisioning towards Active Directory and connected systems. The platform supports identity lifecycle for internal users and service accounts and integrates with HR feeds, AD and line-of-business directories.
Over the next 12 to 24 months the team will run a migration programme toward Microsoft Entra ID Governance. You will design and build the migration path for MIM-managed processes, implement the equivalent business rules in the Entra tooling where appropriate, and work with Azure teams on integration patterns. You will collaborate with the product team and cross-functional teams to ensure testability and operational readiness.
Your responsibilities
- Own and improve MIM workflows and connector configurations to reduce incidents and streamline provisioning outcomes.
- Translate operational requirements into robust .NET components and PowerShell modules that implement lifecycle and reconciliation rules.
- Implement and validate new lifecycle rules for users and groups to Active Directory and downstream systems, reducing manual interventions.
- Document designs, runbooks and implementation details in MS Office and collaboration platforms, and present changes to product and operations teams.
- Mentor colleagues and act as the technical bridge between the product team and cross-functional teams during development and migration activities.
- Run integration, test and deployment activities to ensure changes move cleanly from development into production.
Your profile
Essential skills
- Operational expertise with Microsoft Identity Manager (MIM) at integration and runtime levels, able to diagnose and fix sync and workflow issues.
- Proven .NET development capability, comfortable building components that integrate with MIM and Active Directory.
- Confident PowerShell scripting skills for automation, troubleshooting and deployment tasks.
- Regular use of Microsoft Visual Studio for development and debugging of identity logic.
- Hold or be able to reference Microsoft Identity related certifications and provide contactable references.
Preferred skills
- Practical familiarity with Microsoft Entra ID, Azure App Service, API Management, Application Gateway or Azure Monitor.
- Experience migrating on-premise identity management to Azure-based governance solutions.
