Application Developer (Java, JavaScript) (Full-Stack)

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for an Application Developer (Java, JavaScript) (Full-Stack) based in the United States. This role offers an opportunity to build the application services behind a public health IT monitoring and compliance evidence platform. You will develop Java-based services that ingest public health technology data, monitor published FHIR endpoints, validate resources, and generate reproducible evidence cases. Working across backend services, data pipelines, APIs, and supporting tools, you will help create reliable and repeatable endpoint observation workflows. You will implement deterministic validation rules that make compliance pass/fail decisions, while ensuring AI-assisted components only summarize and support analysis rather than determine final outcomes. The position combines Java and JavaScript development with AWS infrastructure, automated testing, and healthcare interoperability standards. You will collaborate with technical and engineering leads in a part-time, remote contract environment.
