Integration Developer (HL7) - Remote

Fully remote | Full-time | $90,000–$100,000 annual salary

315, LLC builds and operates Cairn, a healthcare revenue cycle management platform running on .NET and Microsoft Azure. Cairn exchanges clinical and billing data with practice EHR systems through HL7 interfaces, and that integration layer is now a full-time job. We're hiring a dedicated integration developer to own it.

This is a specialist role, and we mean that literally: your work is HL7. Building, maintaining, monitoring, and troubleshooting the interfaces that move demographics, scheduling, charges, and results between Cairn and the EHR systems our partner practices run on — eClinicalWorks first among them.

WHAT YOU'LL DO

• Own the HL7 interface layer between Cairn and external EHR systems end to end
• Build and maintain HL7 v2.x message flows (ADT, SIU, DFT, ORU) — mapping, transformation, validation, and error handling
• Monitor interface health, work failed-message queues, and chase down discrepancies to root cause across vendor boundaries
• Onboard new practices: scope the interface requirements, build the feed, test it against real-world data, and take it live
• Document message specifications, mapping decisions, and troubleshooting runbooks
• Follow secure development practices appropriate for a HIPAA-regulated environment

WHY THIS ROLE

Interface work at most companies is a side duty bolted onto another job. Here it's the whole job, with a growing practice roster that makes the pipeline real and permanent. You'll work directly with the architect who built the platform, and your interfaces will be the connective tissue that the entire billing operation runs on. If you're the person who actually enjoys reading a raw HL7 message and knowing exactly which segment broke, this is your room.

We are an equal opportunity employer. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability, or veteran status.

• 3+ years of hands-on, production HL7 v2.x experience — this is the non-negotiable. You should be fluent at the segment level (MSH, PID, PV1, FT1, OBX) and comfortable reading raw messages without a viewer
• Real experience with the message types that matter in ambulatory billing: ADT, SIU, DFT, and ORU
• Working knowledge of an interface engine (Mirth Connect, Rhapsody, Cloverleaf, or similar) or equivalent experience building interfaces in code
• Proficiency with SQL for tracing data across systems
• Strong troubleshooting instincts across vendor boundaries — you'll regularly be the one proving where a message actually died
• Self-directed work habits — you'll be remote, and we trust you to manage your time

NICE TO HAVE

• eClinicalWorks (eCW) interface experience — this moves you to the top of the stack
• C#/.NET experience (Cairn is a .NET platform)
• X12 EDI exposure (837/835) or other healthcare billing data experience
• FHIR familiarity

• Annual salary: $90,000–$100,000
• Individual medical insurance premium 100% employer-paid (dental and vision plans available at employee cost)
• 401(k) with employer match up to 3%
• Life insurance (Basic, Voluntary & AD&D)
• Paid time off: vacation, sick leave, and public holidays
• Fully remote position
