Operations Research / Systems Analyst (ORSA) - Modeling & Simulation Focus

N2IA Technologies•Washington, DC

About The Position

N2IA Technologies is a consulting company specializing in acquisition and contracting support, cost/FinOps, and technology optimization for federal clients. The Operations Research / Systems Analyst (ORSA) – 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. The role develops queueing models, discrete-event simulations, and predictive models to identify process bottlenecks, forecast operational outcomes, and support proactive, data-driven decision-making. The analyst evaluates operational processes and potential changes, builds realistic models incorporating stochastic variation and resource constraints, and applies statistical and machine-learning methods to complex datasets. The position also validates models, communicates uncertainty and limitations, collaborates with data engineering specialists, and presents findings to technical and non-technical audiences. Secret clearance is required, either active or obtainable.

Requirements

At least 8 years of progressive, hands-on operations research experience, including applying queueing theory, simulation, statistical modeling, and predictive analytics to real-world operational problems.
3–5 years of experience supporting DoD or Intelligence Community mission areas such as personnel vetting, industrial security (NISP), counterintelligence, or insider threat.
Bachelor’s degree in operations research, applied mathematics, statistics, industrial engineering, or a related quantitative discipline.
Expert-level knowledge of queueing theory and discrete-event simulation, with demonstrated ability to model complex operational processes.
Hands-on experience with simulation tools such as Arena, AnyLogic, SimPy, or similar.
Strong foundation in statistical modeling, hypothesis testing, experimental design, and time-series analysis.
Hands-on proficiency in an analytical programming language such as Python, R, or SAS, including statistical and machine-learning libraries.
Demonstrated ability to build and validate predictive models that forecast operational outcomes.
Experience working with complex, messy real-world datasets, including missing data, inconsistent formats, and temporal misalignment.
Ability to translate analytical findings into objective, data-backed recommendations for strategic decision-making.
Experience working in secure, classified government environments.
Secret clearance required, active or ability to obtain.
