Senior Software Engineer - AWS

Senior Software Engineer - AWS Healthmark Group Remote, Other / Non-US, United States About this position HealthMark Group is a leading provider of health IT solutions, transforming administrative processes into seamless digital solutions. Founded in 2006 and headquartered in Dallas, Texas, it has been recognized for its rapid growth. We are a mid‑size company modernizing legacy systems and building new products. If you want to build things that matter, this is a good time to join. Role and Responsibilities Senior Software Engineer – AWS to design, build, and evolve our Interoperability platform that retrieves patient records from EHRs and external systems using FHIR based APIs and related interoperability standards. Responsibilities include: 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 for Release of Information 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. 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. Required Experience 6+ years of professional software development experience, with growth in complexity and scope of problems 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 unit, 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. AI Assisted Development Active, daily use of AI coding tools integrated into development workflow. Ability to critically evaluate AI‑generated code for correctness, security, and maintainability. Experience providing AI tools with meaningful context to get higher quality output. Comfortable working in a workplace where AI‑supported delivery is standard. Preferred Experience Deep experience with FHIR resources, profiles, and implementation guides. Familiarity with SMART on FHIR, OAuth2, and healthcare authentication/authorization models. Experience integrating with major EHR platforms (Epic, NextGen, Meditech, etc.). 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 and direct. How You Work You own outcomes, not just tasks. You make decisions with incomplete information and adjust as you learn more. You communicate clearly to different audiences. You are open to feedback and can give it constructively. You have opinions and share them, but can agree to a different direction when necessary. You see problems beyond your immediate work and act on them. You help make other engineers better through code review, pairing, or mentorship. You see AI tools as an enhancer, not a crutch. You are comfortable working remotely and managing your own time. Why This Might Be Interesting / Challenging You will work on real‑world healthcare interoperability problems. Your efforts play a crucial role in retrieving and providing patient records for Release of Information requests. You will help shape a growing FHIR‑based interoperability platform with real scale and impact. You will have real ownership and influence over technical direction. Small team means your contributions are visible and valued. You will work in a shop that takes AI‑assisted development seriously. Remote first culture values outcomes over optics. #J-18808-Ljbffr
