Technical Architect - Healthcare Platforms (FHIR | Angular | .NET | SQL Server)

Key Responsibilities Architecture & Solution Design Assess the current application architecture and identify performance, scalability, reliability, and maintainability challenges. Design a target-state architecture that supports growth from 380+ users to 580+ users and beyond. Define application, data, integration, and security architecture patterns aligned with healthcare best practices. Establish scalability strategies including horizontal scaling, caching, asynchronous processing, and database optimization. Design solutions that maintain high availability and resiliency for critical patient care workflows. Healthcare Interoperability Lead the architecture and implementation of FHIR-based integrations. Design scalable healthcare data exchange mechanisms using HL7 FHIR APIs. Integrate with EHR/EMR systems such as eClinicalWorks, Epic, Cerner, Athena, or equivalent healthcare platforms. Ensure healthcare regulatory compliance including HIPAA and healthcare data security requirements. Performance Engineering Conduct architecture reviews and performance assessments of existing applications. Identify bottlenecks across: Angular UI .NET APIs SQL Server database iIntegration services Infrastructure components Define performance tuning strategies for: API response times Database queries Search operations Reporting workloads Concurrent user handling Create performance benchmarks, capacity planning models, and growth forecasts. Platform Modernization Define modernization roadmaps for legacy components. Recommend cloud-native and microservices adoption where appropriate. Drive implementation of event-driven and loosely coupled architectures. Introduce observability, monitoring, logging, and telemetry frameworks. Technical Leadership Work closely with Product Owners, Delivery Leaders, Engineers, and Business Stakeholders. Mentor development teams on architecture best practices and coding standards. Conduct architecture governance reviews. Drive security, reliability, and quality initiatives throughout the SDLC. 12+ years of software engineering experience. 5+ years as a Solution Architect or Technical Architect.
