Senior .NET Developer to join our core team focused on the "eOrder" initiative—a critical project designed to modernize and streamline the electronic transmission and processing of laboratory and radiology orders between our Electronic Health Record (EHR) system and various external providers and internal services. This project is at the intersection of modern software development and mission-critical healthcare data exchange.
You will be responsible for the full lifecycle development, from design and implementation to deployment and maintenance, of integration services and APIs that handle high-volume clinical data. A deep understanding of healthcare messaging standards, particularly HL7, is mandatory for success in this role.
Job Duties:
• Design, develop, and maintain robust integration engines and middleware using C#/.NET Core to process, parse, transform, and validate HL7 messages (v2 and potentially v3/CDA) for orders (ORM) and results (ORU).
• Develop secure, high-performance RESTful APIs and microservices using ASP.NET Core for internal and external consumption related to order management and status tracking.
• Work with relational (SQL Server) and NoSQL databases, ensuring data integrity, optimized queries, and efficient storage of order metadata and transactional logs.
• Implement and maintain CI/CD pipelines and deploy services using Azure DevOps, focusing on scalability, security, and performance within the Azure cloud environment.
• Act as a subject matter expert during troubleshooting sessions, diagnosing issues related to message routing, transport protocols (MLLP, HTTPS), and data mapping within the integration layer.
• Work closely with clinical analysts, interface engineers, and testing teams to ensure solutions meet strict regulatory compliance and clinical requirements.
Qualifications and Requirements:
• 7+ years of professional software development experience.
• Expert proficiency in C# and the .NET / .NET Core framework.
• 3+ years of experience working specifically with HL7 messaging standards (v2), including detailed knowledge of segments like PID, PV1, OBR, ORC, and message types like ORM (Orders) and ORU (Results).
• Demonstrable experience developing and deploying services using ASP.NET Core (Web API, Microservices).
• Strong understanding of modern architectural patterns (e.g., Microservices, Event-Driven Architecture).
• Proficiency in SQL and experience with SQL Server, including stored procedures and complex query optimization.
• Experience with SSIS packages.
• Experience with reporting tools such as SSRS, Power BI, or similar platforms.
• Familiarity with cloud platforms (preferably Azure, including App Services, Functions, and Service BEvent Hub).
• Bachelor''s degree in computer science or a related field.
Highly Desired Qualifications (Nice-to-Haves)
• Prior experience in a clinical or laboratory environment.
