Comp:

$215K to $275K base plus equity. Visa sponsorship available.

• Own the backend services, APIs and data models behind the internal tools that run the business: case assignment, radiologist peer review and analytics
• Own the integration layer that connects the platform to hospital systems (PACS, RIS, EHRs) over DICOM and HL7
• Work directly with customers during onboarding to understand their systems and build custom integrations
• Find process gaps and automate them across product and operations
• Make architecture decisions on your own and ship end to end, with no handholding

• Strong systems design judgment, especially integrating with external customer systems
• Healthcare experience is NOT required. DICOM, HL7 or HIPAA exposure is a plus
