Job description
From HHAeXchange’s job post, as they wrote it.
Essential Job Duties
Full-stack delivery: Design, build, test, and maintain reliable features across the C#/.NET back end, the TypeScript/Angular front end, and the database. Technical lead for the team's work: Break larger work into smaller tasks, lead the design of features and services in the team's area, and write short design documents that other engineers can review. Healthcare data exchange: Build and maintain integrations and transactions that use HL7, FHIR, and X12 EDI, following the company's interoperability and architecture standards. Legacy modernization: Contribute to modernizing legacy functionality. Move screens and functions to new services and a new front end, confirm that the new behavior matches the existing behavior by using automated tests, and release changes in small steps. Code quality: Write clear, tested code. Review the code of other engineers and give specific, respectful feedback. Help keep code organized, automated, and easy to change. Performance and data: Apply data modeling techniques, review the performance of code and database queries, and make improvements when measurements show a problem. Security, PHI, and accessibility: Apply secure coding practices, protect PHI, follow HIPAA requirements, and build user interfaces that meet Web Content Accessibility Guidelines (WCAG). Production support: Investigate and resolve defects and incidents in the services the team owns, and document the cause and the fix. AI-assisted development: Use AI coding tools responsibly. Review and test all AI-generated code before it is merged, and never enter PHI or other protected data into tools that the company has not approved. Mentorship: Coach less experienced engineers through code reviews, pairing, and design discussions. Collaboration: Work with Product Managers, Product Owners, Quality Assurance, and other engineers to clarify requirements, estimate work, and report progress and risks clearly. Standards: Follow the team and company engineering standards, and propose improvements when a standard does not work well in practice.
