Senior Complex Systems Engineer
About The Position
MITRE’s Complex Systems Department is seeking a Complex Systems Modeler to apply modeling, operational analysis, and applied research to problems of national importance. Work may span national security, healthcare, and transportation, with opportunities to interact directly with government leaders and help evaluate solutions through rigorous analysis. The department combines data analysis with modeling and simulation to help sponsors understand complex dynamics, assess potential interventions, and make analytically defensible decisions. It builds deployable tools that let sponsors explore models and causality. Employees work across multiple projects, share ideas across government programs, and contribute to independent research in areas relevant to government partners. The position requires at least three days per week onsite. The hired candidate must obtain a Top Secret/SCI clearance within one year of hire; candidates must be U.S. citizens to be eligible for a security clearance.
Requirements
- Typically, at least 5 years of related experience with a bachelor’s degree in a quantitative field; or 3 years with a master’s degree; or a Ph.D. with relevant experience and ability to contribute at this job step.
- Excellent written and verbal communication skills.
- Ability to formulate rigorous models from loosely defined or underspecified research questions and requirements.
- Expertise using Agentic-AI and at least one of the following: agent-based modeling, discrete event modeling, system dynamics, or applied statistical modeling/machine learning for complex systems.
- Applied experience modeling and analyzing spatiotemporal datasets.
- Experience manipulating large datasets using at least one modern programming language or business intelligence platform, such as Python, R, SAS, MATLAB, Java, or C++.
- Experience using commercial off-the-shelf tools or writing programs to visualize multidimensional data, such as Tableau, ggplot2, Plotly, matplotlib, seaborn, or D3.js.
- Ability to apply, modify, and formulate algorithms and processes to solve challenging problems.
- Must be eligible to obtain and maintain a U.S. Government Top Secret/SCI security clearance; U.S. citizenship is required for clearance eligibility.
- Must work onsite at least 3 days per week.
Nice To Haves
- Experience developing models using multiple methodologies.
- Experience leading stakeholder- or funder-facing engagements and providing day-to-day tasking to junior staff.
- Experience developing interactive visualizations or configuring dashboards with open-source web technologies such as Angular, Vue, React, or D3.js, or frameworks such as Shiny or Plotly Dash.
- Experience working with databases such as PostgreSQL, Oracle, MySQL, MongoDB, or Neo4j.
- Experience developing programmatic solutions collaboratively using tools such as Git, Mercurial, or SVN.
- Familiarity with ArcGIS or other GIS software or analytic tools.
- Experience using notebooks such as Jupyter, R Markdown, or Zeppelin.
- Experience developing data-intensive, full-stack containerized web applications using Node.js, Flask, Django, or similar technologies, or demonstrated ability manipulating large datasets and time-series data.
- Comfort with modern AI tools, including large language models, and their application, evaluation, and validation.
- Active TS, TS/SCI, or TS/SCI with polygraph clearance.
Responsibilities
- Formulate and develop models and simulations of real-world problems involving complex dynamic systems.
- Develop research questions and test hypotheses in open-ended tasking.
- Work with government sponsors to understand challenges, evaluate possible solutions, and conduct actionable analyses.
- Support the development and application of analytic models to sponsor challenges, adapting and learning in a fast-paced environment.
- Present results in an intuitive, actionable manner to audiences with varying technical expertise.
- Stay current on open-source, industry, academic, and U.S. Government methods and tools for modeling, analysis, data science, visualization, and engineering.
- Take initiative in owning work and collaborate as a teammate.
