Domain Architect- IAM​/M365

Domain Architect is accountable for defining and delivering architecture strategy, solution guidance, and technical oversight within a specific domain (Information Security, Infrastructure, Application, etc.). This role bridges enterprise architectural direction with domain-specific initiatives, ensuring designs are scalable, secure, and aligned with business priorities. The Domain Architect collaborates closely with solution architects, developers, and business stakeholders to ensure that architectural designs enable agility, performance, and long-term maintainability.

The Domain Architect will specialize within IAM and requires expertise in Microsoft 365.

This role is located in Springfield, MO and will require on-site work on a regular basis.

• Define the domain-specific architecture roadmap in alignment with enterprise strategy and portfolio objectives.
• Establish standards, principles, and best practices that support operational efficiency, scalability, and interoperability.
• Collaborate with enterprise architects to ensure alignment of domain strategy to enterprise target state.
• Create architecture artifacts high-level design and low-level design such as system design documents, integration diagrams, and data flow models.
• Lead domain-specific solution architecture, including application, integration, infrastructure, and security components.
• Create high-quality architecture deliverables including blueprints, diagrams, and models.
• Partner with delivery teams to ensure implementation fidelity to architecture vision.
• Establish and drive adherence to domain governance frameworks.
• Participate in Architecture Review Board (ARB) and lead peer design reviews within the domain.
• Conduct security assessments and regulatory compliance evaluations in coordination with Info Sec.
