As an 8(a), HUBZone, and Service-Disabled Veteran-Owned Small Business (SDVOSB), we empower government and private sector clients by delivering tailored solutions that drive operational success, sustainability, and growth. Built on integrity, collaboration, and excellence, we’re more than a service provider-we’re your trusted partner in innovation.\nPosition Summary\nThe Application Developer builds the Java services that ingest public health IT data, observe deployed FHIR endpoints, validate what they find, and assemble reproducible evidence cases for Project Argos. You write the deterministic validators that make pass/fail determinations, plus the retry, rate-limiting, and instrumentation logic that keeps monitoring safe and repeatable. Agentic components may summarize and draft, but they do not make final compliance calls, and your code enforces that boundary.\nType:\nThe position is open to both W2 and 1099\nPart-time, variable hours, 10 - 29 hours a week\n1 year contract\nPay:\nW2: pay rate of $55 - $60/hr\n1099: $65 - $70/hr\nWorks with: Technical Lead, AI/Engineering Lead, Senior Systems Engineer, and Project Manager.\nAbout Broadway Ventures and Project Argos\nBroadway Ventures, LLC is a Service-Disabled Veteran-Owned Small Business (SDVOSB) and HUBZone federal contractor headquartered in Vicksburg, Mississippi, with operations in the Madison/Huntsville, Alabama area.\nProject Argos is an agentic AI proof of concept for the Office of the National Coordinator for Health IT (ONC). Broadway is the prime contractor, with Audacious Inquiry as subcontractor. The pipeline pulls published API endpoint data for roughly 290 certified health IT products from the Certified Health IT Product List (CHPL), tests those endpoints on a repeatable schedule, and builds reproducible evidence cases for compliance gaps under 45 CFR Part 170. It runs in a contractor-hosted AWS GovCloud environment, and a qualified human reviews every finding before it becomes a confirmed issue.\nKey Responsibilities\n- Build ingestion connectors for CHPL, Service Base URL Lists, developer-published FHIR Bundles, Lantern, and other approved public sources. Preserve raw artifacts, timestamps, request metadata, response headers, and hashes.\n- Normalize developer, product, version, criterion, CHPL ID, endpoint, organization, and validation records into the project's common data model in DynamoDB, with lineage and source-of-truth precedence rules.\n- Implement publication checks that fetch endpoint lists and classify availability failures: URL not found, timeouts, obscuring redirects, malformed responses, and non-machine-readable content.\n- Build safe, non-authenticated endpoint observation for metadata and CapabilityStatement retrieval, and detect drift as endpoints are added, removed, moved, or changed.\n- Run FHIR R4 validation against Endpoint, Organization, and Bundle resources, preserving both raw and normalized results.\n- Build the evidence case package with source metadata, request and response logs, validation outputs, severity, and rule traceability. Support deduplication, clustering, and export to Government-designated systems.\n- Design scheduling, retry and backoff, rate limiting, error handling, and audit logging for pipeline and agentic components.\n- Make test runs replayable so a reviewer can re-run a test for any evidence case.\n- Write unit and integration tests, including stub and mock endpoints for failure scenarios. Participate in code review and keep technical documentation current.\n- Keep the code from requesting, collecting, or storing patient data, PHI, credentials, or tokens unless the Government authorizes it in writing.\nRequired Qualifications\n- 5+ years of Java (17+) development, including concurrency and networked services\n- 3+ years of Spring Boot or an equivalent framework\n- 2+ years of JavaScript/Node for tooling and front-end development\n- 4+ years building REST APIs and working with JSON\n- 3+ years of working knowledge of HTTP and TLS fundamentals\n- 3+ years with the AWS SDK, DynamoDB data modeling, and S3\n- 2+ years building and running containerized services\n- 4+ years of automated testing (JUnit, integration tests)\n- 3+ years of code review and technical documentation\n- 1+ year building with LLM APIs or using AI coding assistants in development, including testing and validating AI-generated output\n- Authorized to work in the United States\nPreferredQualifications\n- HAPI FHIR or other FHIR R4 validation experience (US Core, CapabilityStatements)\n- HTTP client internals, including timing and connection instrumentation\n- Scheduling, retry and backoff, and rate-limiting design\n- Testcontainers or stub and mock services for failure testing\n- SMART on FHIR, Inferno, or ONC certification testing\n- Health IT or federal program experience\nWhat to Expect Next:\nAfter submitting your application, our recruiting team will review your qualifications. This may include a brief telephone interview or email communication to verify resume details and discuss compensation expectations. Interviews will be conducted with the most qualified candidates.
