About this Software Devoloper role at Leidos
Leidos is seeking a Mid-Level Software Developer to support a highly technical, interdisciplinary program in partnership with the Defense Threat Reduction Agency (DTRA) and the Defense Intelligence Agency (DIA). You will build and optimize software solutions that physically and functionally characterize hardened facilities and Weapons of Mass Destruction (WMD) processes. Your code will directly drive physics-based models and effects-based simulations, empowering scientific assessments and increasing overall operational efficiency.
.
Key Responsibilities
Scientific & Engineering Software Integration: Develop, maintain, and modernize software algorithms that convert complex scientific data into physics-based models.
Effects-Based Simulation Support: Build backend services and cloud-native data pipelines to support large-scale effects-based simulations for WMD and hardened facility characterization.
Workflow Automation & ETL: Architect and maintain reliable ETL data flows to ingest massive datasets from varied scientific, engineering, and intelligence formats.
Cross-Domain Data Transfer: Implement, secure, and maintain cross-domain transfer solutions to safely move critical data across unclassified and classified networks.
Cross-Discipline Collaboration: Work hand-in-hand with scientists, physicists, hardware engineers, and defense analysts to translate vague, highly complex requirements into functional, user-friendly software prototypes.
