Senior .NET Modernization Architect

We are seeking a .NET Solutions Architect to analyze, reverse-engineer, and modernize complex enterprise applications across legacy monolithic, n-tier, and contemporary .NET platforms.

This role focuses on uncovering undocumented business logic, data dependencies, and architectural constraints within legacy systems and translating those findings into scalable, modern solution designs. The ideal candidate is hands-on, analytical, and comfortable navigating poorly documented environments to extract functional and non-functional requirements.
Experience within the Healthcare Payor domain is a strong advantage and will accelerate alignment with business workflows and regulatory requirements.

Responsibilities:
• Reverse engineer legacy monolithic and n-Tier .NET applications to understand architecture, business rules, data flows, and integration points
• Analyze poorly documented systems to extract functional and non-functional requirements
• Produce current-state architecture diagrams, data flow models, and dependency maps
• Identify technical debt, architectural anti-patterns, and modernization risks
• Design target state architectures to decompose monolithic systems into modular services, including microservices where appropriate
• Define modernization strategies, including strangler patterns, phased migrations, or parallel-run approaches, to minimize business disruption
• Lead refactoring initiatives to improve maintainability, scalability, and performance
• Analyze legacy database schemas, stored procedures, and embedded business logic to inform modernization decisions
• Support data migration and transformation strategies during system transition
• Translate complex legacy findings into clear documentation for technical and non-technical stakeholders
• Partner with business SMEs to ensure technical designs align with operational workflows and compliance requirements

Required Experience:
• Advanced experience in reverse engineering legacy monolithic or n-Tier enterprise .NET applications
• Deep expertise in C# and the .NET ecosystem, including legacy .NET Framework (Web Forms, WCF, MVC) and modern .NET (.NET Core / .NET 6+)
• Strong experience analyzing legacy database schemas and stored logic
• Demonstrated ability to identify technical debt and assess architectural risk
• Experience defining modernization strategies and making refactor vs. rebuild vs. re-platform decisions
• Proven ability to extract and document undocumented system behavior through code inspection, database analysis, and runtime evaluation
• Strong architectural communication skills and the ability to translate complexity for diverse stakeholders

Preferred Experience:
• Experience within the Healthcare Payor domain, including claims adjudication, member enrollment, provider networks, benefits configuration, or utilization management
• Understanding of regulatory and compliance requirements such as HIPAA, data privacy, and auditability
• Experience supporting large-scale modernization initiatives in regulated enterprise environments
