The Operations Research (OR) Analyst - Modeling & Simulation Focus provides advanced process modeling, simulation, statistical analysis, and predictive analytics across a Federal Agency's personnel vetting, industrial security, and counterintelligence operations. This position develops queueing models, discrete-event simulations, and predictive models that enable the Federal Agency to identify process bottlenecks, forecast operational outcomes, and transition from reactive reporting toward proactive, data-driven decision support. Essential Duties & Responsibilities Process Modeling & Simulation Develop queueing models and discrete-event simulations to identify bottlenecks and inefficiencies within operational pipelines (personnel vetting, facility inspections, investigative workflows) Analyze and recommend process improvements that reduce turnaround times while maintaining required quality and compliance standards Conduct scenario analysis and what-if modeling to evaluate the impact of proposed process changes, policy modifications, or resource reallocations Build simulation models that capture stochastic variation, resource constraints, and operational policies to provide realistic operational forecasts Statistical & Predictive Modeling Apply statistical analysis and risk modeling to prioritize assessments, optimize resource deployment, and identify emerging risk or threat vectors Utilize advanced mathematical and statistical modeling to detect anomalies, patterns, and trends within large, complex, and disparate data sets Develop predictive models that enhance the organization's ability to forecast workload, prioritize cases, and respond to emerging conditions and threats Apply machine learning techniques for classification, clustering, anomaly detection, and pattern recognition in support of counterintelligence and insider threat missions Model Validation & Analysis Validate model assumptions and outputs against historical operational data and subject matter expert input Conduct sensitivity analysis to understand model behavior under varying assumptions and parameter values Quantify and communicate uncertainty in model predictions and recommendations Document modeling methodologies, assumptions, and limitations to ensure transparency and reproducibility Collaboration & Communication Work closely with data engineering specialists to define analytical dataset requirements and ensure data suitability for modeling Translate analytical outputs into objective, data-driven recommendations that support strategic and operational decision-making Present complex modeling results to technical and non-technical audiences through visualizations and clear narratives Participate in cross-functional team activities to maintain technical standards and share knowledge   Required Skills/Experience 8+ years of progressive, hands-on operations research experience, including demonstrated application of queueing theory, simulation, statistical modeling, and predictive analytics to real-world operational problems 3–5 years of that experience supporting DoD or Intelligence Community mission areas such as personnel vetting, industrial security (NISP), counterintelligence, or insider threat Expert-level knowledge of queueing theory and discrete-event simulation, with demonstrated ability to model complex operational processes Hands-on experience with simulation tools (Arena, AnyLogic, SimPy, or similar) Strong foundation in statistical modeling, hypothesis testing, experimental design, and time-series analysis Demonstrated, hands-on proficiency in an analytical programming language (Python, R, or SAS), including statistical and machine learning libraries Proven ability to build and validate predictive models that forecast operational outcomes Experience working with complex, messy real-world datasets (missing data, inconsistent for
