Note: The job is a remote job and is open to candidates in USA. HealthMark Group is a leading provider of health IT solutions for healthcare providers across the country. They are seeking a Senior Software Engineer - Interop to design, build, and evolve their Interoperability platform, focusing on securely retrieving patient records from EHRs and external healthcare systems using FHIR based APIs.
Responsibilities
- 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
Skills
- 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
- Deep experience with FHIR resources, profiles, and implementation guides, including real-world interoperability constraints
- Familiarity with SMART on FHIR, OAuth2, and healthcare authentication/authorization models
- Experience integrating with major EHR platforms (Epic, NextGen, Meditech, etc.)
- Healthcare domain experience, including HIPAA compliant patient data handling
- Experience with asynchronous workflows, messaging, and retry semantics for external system integration
- Hands on AWS experience (EC2, SQS, SNS, Lambda, RDS)
- History of leading technical projects or initiatives
- Experience with agentic AI workflows—letting AI tools operate with more autonomy while you supervise, review, and direct
Benefits
- Fully remote work environment
