are seeking a backend-focused Software Engineer to help build a modeling and decision-support application for the Defense Health Agency (DHA). The platform enables planners to explore complex healthcare-system scenarios through data integration, simulation, and interactive analysis. This is a hands-on software engineering position for someone who enjoys working across the full software development lifecycle. The Software Engineer will design backend services, build data and simulation pipelines, contribute to cloud architecture, and carry features from initial requirements through deployment and demonstration. The application includes a web-based user experience, but the role’s current emphasis is backend engineering, cloud infrastructure, data processing, and complex systems design.
