MUST HAVE FHIR EXPERIENCE!!

 

Join one of the fastest-growing healthcare technology companies in the country.

This organization has grown 175% over the past 6 years, recognized multiple times by Dallas 100 and Inc. 5000 as one of the region’s and nation’s fastest-growing companies. They’re building modern digital healthcare solutions at scale—and now they’re growing their interoperability engineering team.

 

This is a hands-on, high-impact role where you’ll design and build new products, automate workflows, modernize legacy systems, and work on real-world healthcare interoperability problems—not toy demos or throwaway POCs.

 

If you enjoy solving complex integration challenges, shaping architecture, and using AI coding tools daily to accelerate delivery, this is the team to join.

🌟 What You’ll Do

* Design, build, and maintain backend services and APIs using FHIR, REST, and interoperability standards
* Build workflows supporting Release of Information (ROI): identity matching, record discovery, retrieval, normalization, and delivery
* Integrate with EHR vendors and HIEs using FHIR, RESTful APIs, event-driven patterns
* Modernize legacy integrations and drive transformation of the core platform
* Own technical roadmaps for interoperability components
* Use AI coding tools (Copilot, JetBrains AI, etc.) for code generation, debugging, refactoring, and faster iteration
* Lead code reviews and influence engineering standards
* Debug issues across distributed systems and complex third-party integrations
* Collaborate across Product, Ops, Engineering, and Compliance
* Proactively identify risks related to data quality, system dependencies, or interoperability constraints

🔎 What You Bring

* Strong Microsoft stack expertise: C#, .NET Framework / .NET 6+, Web API, MVC, EF, SQL Server
* Experience designing & operating API-driven, distributed systems in production
* Direct FHIR integration experience (resources, profiles, implementation guides)
* Daily user of AI coding tools with the ability to validate and improve AI-generated code
* Strong SQL modeling, performance tuning, and data consistency skills
* Experience integrating software with data-heavy third-party systems
* Automated testing + CI/CD proficiency
* Git fluency
* AWS experience (Lambda, EC2, SQS, SNS, RDS)—Azure a plus
* DevOps best practices

⭐ Preferred Experience

* Apache NiFi (HIGHLY preferred)
* Integrations with major EHRs: Epic, NextGen, Meditech, etc.
* HIPAA-compliant systems
* Asynchronous messaging patterns, retries, distributed integrations
* Technical leadership
* Experience with agentic AI workflows (AI doing more with human supervision)

🔥 Why This Role Is Exciting

* Solve real healthcare interoperability problems with direct impact
* Build and evolve a FHIR-based interoperability platform at scale
* Have true ownership and influence over architecture decisions
* Join a small, high-impact team where your contributions are visible
* Work in an engineering culture that treats AI-assisted development as a daily practice, not a buzzword
* Remote-first, outcome-driven environment
