A Role with Purpose and Impact

Dev Technology is supporting the modernization of a mission-critical federal scheduling and workflow platform built on the Microsoft ecosystem. This role is responsible for defining a secure, scalable, and maintainable enterprise architecture that aligns business needs with the Government's Microsoft-based enterprise environment.

You will work across business, application, data, integration, security, infrastructure, and delivery teams to design solutions leveraging Microsoft Power Platform, Azure, Dynamics 365, Microsoft 365, and modern .NET technologies. The role requires strong technical judgment, experience evaluating SaaS, PaaS, and hybrid architectures, and a practical commitment to configuration-first solutions while minimizing custom development.

This position is ideal for a senior technical leader who can establish architectural direction, communicate technical tradeoffs to executive and technical stakeholders, and remain engaged throughout implementation to ensure architectural integrity from design through production.
Architecture Leadership and Technical Delivery

This role blends enterprise architecture leadership with hands-on technical guidance. You will:

• Design end-to-end solution architecture across application, integration, data, security, infrastructure, environments, and deployment
• Architect Microsoft Power Platform solutions including Power Apps, Power Automate, Dataverse, and Power Pages
• Design scalable Azure-based solutions utilizing Azure App Services, Azure Functions, Azure API Management, Logic Apps, Azure Service Bus, Azure SQL, and other Azure Integration Services
• Define modular system components, APIs, data models, security controls, availability, scalability, and performance strategies
• Guide configuration and extension of Microsoft SaaS and PaaS capabilities while minimizing custom code
• Design integrations using REST APIs, Microsoft Graph, Azure Integration Services, .NET services, and enterprise messaging patterns
• Lead architecture reviews, evaluate design alternatives, and incorporate Government feedback into technical architecture artifacts
• Collaborate with development teams using C#, .NET, ASP.NET Core, JavaScript/Type Script, and Power Platform custom components when extensions are required

You will remain engaged throughout delivery by reviewing solution designs, application configurations, .NET code, Power Platform implementations, Azure resources, integration approaches, and production readiness activities while ensuring architecture documentation remains current.
