Senior Software Engineer – AWS

Job Description:

• Design, build, and maintain backend services and APIs that retrieve and process patient records from EHRs and health systems using FHIR (R4) and related interoperability standards.
• Build and evolve interoperability workflows that support Release of Information (ROI) use cases, including patient identity matching, record discovery, data retrieval, and downstream delivery.
• Integrate with external healthcare systems, EHR vendors, and health information networks using FHIR, RESTful APIs, and event driven patterns.
• Work across modern .NET services and existing platforms, modernizing legacy integrations where appropriate.
• Own technical roadmaps for interoperability components—balancing reliability, scalability, compliance, and delivery speed.
• Use AI coding tools daily to accelerate development—generating code, debugging, refactoring, and navigating unfamiliar healthcare focused codebases.
• Review AI generated output with the same rigor applied to any production code—understanding what it produces, not just accepting it.
• Write clean, testable, well documented code with a strong emphasis on observability and operational readiness.
• Lead code reviews and help maintain engineering standards across backend services and integrations.
• Debug and resolve issues across distributed systems, including third party integrations and external dependencies.
• Collaborate with product, operations, and compliance teams to translate healthcare and ROI requirements into technical solutions.
• Identify risks related to data quality, external system dependencies, and interoperability constraints before they become incidents.
• Mentor other engineers, particularly around healthcare integrations and backend service design.

Requirements:

• 6+ years of professional software development experience, with growth in the complexity and scope of problems you have tackled.
• Strong proficiency in the Microsoft stack (C#, .NET Framework / .NET 6+, ASP.NET Web API, ASP.NET MVC, Entity Framework, SQL Server)
• Experience building and operating API driven, distributed systems in production environments.
• Direct experience with healthcare interoperability, particularly FHIR based integrations.
• Solid understanding of relational data modeling, SQL performance, and data consistency in integration heavy systems
• Experience integrating with third-party systems where reliability, error handling, and observability are critical.
• Demonstrated automated testing practices across units, integration, and end-to-end testing.
• Fluency with Git and collaborative development workflows
• Experience deploying and operating services in AWS or Azure
• Proficiency with CI/CD and DevOps practices
• Bachelor’s degree in CS or related field, or equivalent hands-on experience
• Active, daily use of AI coding tools integrated into your development workflow—not just asking a chatbot occasional questions but using AI as a core part of how you write, review, and ship code.
• Ability to critically evaluate AI generated code for correctness, security, and maintainability.
• Experience providing AI tools with meaningful context (codebase access, architecture constraints, project conventions) to get higher quality output.
• At ease in a workplace where AI-supported delivery is the standard rather than a choice.
