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

Remote - United States

At Broadway Ventures, we transform challenges into opportunities with expert program management, cutting-edge technology, and innovative consulting solutions. 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.

Position Summary

The 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.

Type:

  • The position is open to both W2 and 1099
  • Part-time, variable hours, 10 - 29 hours a week
  • 1 year contract

Pay:

  • W2: pay rate of $55 - $60/hr
  • 1099: $65 - $70/hr

Works with: Technical Lead, AI/Engineering Lead, Senior Systems Engineer, and Project Manager.

About Broadway Ventures and Project Argos

Broadway 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.

Project 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.

Key Responsibilities

- 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.
- 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.
- Implement publication checks that fetch endpoint lists and classify availability failures: URL not found, timeouts, obscuring redirects, malformed responses, and non-machine-readable content.
- Build safe, non-authenticated endpoint observation for metadata and CapabilityStatement retrieval, and detect drift as endpoints are added, removed, moved, or changed.
- Run FHIR R4 validation against Endpoint, Organization, and Bundle resources, preserving both raw and normalized results.
- 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.
- Design scheduling, retry and backoff, rate limiting, error handling, and audit logging for pipeline and agentic components.
- Make test runs replayable so a reviewer can re-run a test for any evidence case.
- Write unit and integration tests, including stub and mock endpoints for failure scenarios. Participate in code review and keep technical documentation current.
- Keep the code from requesting, collecting, or storing patient data, PHI, credentials, or tokens unless the Government authorizes it in writing.

Required Qualifications

- 5+ years of Java (17+) development, including concurrency and networked services
- 3+ years of Spring Boot or an equivalent framework
- 2+ years of JavaScript/Node for tooling and front-end development
- 4+ years building REST APIs and working with JSON
- 3+ years of working knowledge of HTTP and TLS fundamentals
- 3+ years with the AWS SDK, DynamoDB data modeling, and S3
- 2+ years building and running containerized services
- 4+ years of automated testing (JUnit, integration tests)
- 3+ years of code review and technical documentation
- 1+ year building with LLM APIs or using AI coding assistants in development, including testing and validating AI-generated output
- Authorized to work in the United States

PreferredQualifications

- HAPI FHIR or other FHIR R4 validation experience (US Core, CapabilityStatements)
- HTTP client internals, including timing and connection instrumentation
- Scheduling, retry and backoff, and rate-limiting design
- Testcontainers or stub and mock services for failure testing
- SMART on FHIR, Inferno, or ONC certification testing
- Health IT or federal program experience

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
