## Summary

Mission Technologies, a division of Huntington Ingalls Industries, is seeking a Data Scientist to support the Joint Training Synthetic Environment (JTSE) and JLVC Modernization effort under the Joint Staff J7 (JS J 7) contract. This role focuses on developing advanced analytics, AI/ML models, and data architectures that enhance joint training, simulation, and decision support capabilities.

## What You Will Do
• Lead end to end data science workflows, including problem definition, data acquisition, feature engineering, model development, evaluation, deployment, and lifecycle monitoring.
• Translate operational and training objectives into data driven solutions by defining analytical approaches and data requirements for integrating advanced AI/ML models into JTSE and Joint Training Tools.
• Design and maintain scalable data pipelines and architectures that support real time and near real time ingestion, processing, and analysis of operational and test & evaluation data.
• Develop, train, and fine tune machine learning models — including large scale and foundation models to enhance simulation fidelity, decision support, and training outcomes.
• Ensure data consistency and interoperability across multiple sources, systems, and stakeholders within a unified analytics environment.
• Integrate AI/ML models into simulation and synthetic environments, including the Fully Informed Simulation Environment (FISE), to support advanced analytics and dynamic scenario generation.
• Define, implement, and enforce data standards, schemas, and governance practices to ensure data quality and compliance.
• Support exercise planning, execution, and after action analysis by enabling predictive analytics, anomaly detection, performance metrics, and other advanced analyses.
• Collaborate with cross functional teams — including government stakeholders and mission partners — to align data science solutions with operational requirements and modernization goals.
• Conduct model validation, testing, and performance assessments to ensure accuracy, robustness, and mission alignment.
• Identify and mitigate risks related to data quality, model bias, scalability, and operational performance.
• Support MLOps/DevSecOps practices to enable secure, repeatable, and continuous delivery of data science capabilities.
• Document data pipelines, models, methodologies, and analytical findings for technical and non technical audiences
