Mid-Level Model Based Systems Engineer

PMAT•Denver, CO

About The Position

PMAT is seeking an experienced mid-level Model-Based Systems Engineer (MBSE) to support enterprise architecture development, digital engineering, and system-of-systems (SoS) integration across Navy operational and technical environments. The role supports the design, development, integration, and verification of complex systems for defense and national security missions. It helps establish and maintain standardized architecture development processes, governance frameworks, data structures, and modeling practices to enable consistent engineering and informed organizational decision-making. The engineer will collaborate with systems and mission engineers, cybersecurity personnel, data engineers, Palantir developers, software developers, and other technical stakeholders to connect architectural models, operational data, requirements, and engineering artifacts in digital environments. The position applies systems engineering fundamentals and model-based methodologies to translate operational requirements into structured architectures, data models, and actionable engineering insights for capability development, integration, and sustainment. The role includes developing and maintaining system architectures, requirements, technical baselines, models, interfaces, and engineering documentation; supporting requirements traceability, analysis, and change management; and applying models to engineering analysis, trade studies, simulation, and risk assessment. It also supports system integration, interoperability, verification and validation, digital engineering practices, model configuration management, and technical reviews. The engineer independently executes assigned work, coordinates with technical leads and program management, communicates findings to stakeholders, and provides technical guidance to junior engineers. The position requires U.S. citizenship and a SECRET security clearance. Work may take place at PMAT offices or, in some cases, a government facility. The listed preferred locations are Washington, D.C., Virginia, and Maryland; Denver, Colorado is listed as remote. Travel is 15% CONUS and OCONUS and may support customer engagement, team coordination, or business development.

Requirements

2–5 years of professional systems engineering experience.
At least 4 years of hands-on MBSE experience using SysML or equivalent modeling methodologies.

Understanding of architecture development processes, governance practices, modeling standards, configuration management, and engineering lifecycle management.
Experience developing or supporting data models, data dictionaries, information architectures, metadata definitions, or structured engineering data repositories.
Experience integrating engineering models, technical data, requirements, and system information across multiple disciplines, platforms, or organizational environments.
Understanding of digital thread concepts and connected engineering information for requirements traceability, system integration, and lifecycle decision-making.
Experience collaborating with systems engineers, mission engineers, software developers, cybersecurity personnel, data engineers, and other technical stakeholders.
Understanding of cybersecurity principles, risk management, security requirements, and their application within systems engineering and acquisition processes.
Strong analytical and problem-solving skills, including the ability to evaluate complex system relationships, identify architectural gaps, and develop actionable recommendations.
Strong written and verbal communication skills, including developing technical documentation, communicating architectural concepts, and presenting findings to technical and program leadership.
Bachelor's degree in Systems Engineering, Aerospace Engineering, a related technical discipline, or equivalent experience.
U.S. citizenship required.
SECRET security clearance required.
