Model Based Systems Engineer

PMAT•San Diego, CA

3d•Onsite

About The Position

PMAT is seeking an experienced 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 helps establish and maintain standardized architecture development processes, governance frameworks, data structures, and modeling practices that support consistent engineering and informed decision-making. The engineer will collaborate with systems engineers, mission engineering teams, cybersecurity personnel, data engineers, and Palantir developers to integrate architectural models, operational data, and engineering artifacts into connected digital environments, including Maven Smart System (MSS). The position applies systems engineering and model-based methodologies to translate operational requirements into structured architectures, data models, and actionable engineering insights supporting capability development, integration, and sustainment. It supports the engineering and acquisition lifecycle, including architecture design and analysis, requirements development, integration, verification, validation, cybersecurity, and sustainment. Work is 100% on-site in San Diego, California, with work at PMAT offices and, in some cases, a government facility. Travel is 15% CONUS and OCONUS for customer engagement, team coordination, and potentially business development. U.S. citizenship and a SECRET security clearance are required; TS/SCI eligibility is preferred.

Requirements

Strong experience performing Model-Based Systems Engineering, systems engineering, enterprise architecture development, digital engineering, or related technical disciplines.
Experience developing, maintaining, and analyzing system or SoS architectures, requirements, interfaces, operational workflows, and technical dependencies.
Experience using MBSE methodologies, modeling languages, and collaborative digital engineering environments to support system design, analysis, integration, verification, and validation.
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 improving 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 to align architectures with operational and technical requirements.
Understanding of cybersecurity principles, risk management, security requirements, and their application within systems engineering and acquisition processes.
Strong analytical and problem-solving skills, including evaluating complex system relationships, identifying architectural gaps, and developing actionable engineering recommendations.
Strong written and verbal communication skills, including developing technical documentation, communicating architectural concepts, and presenting engineering findings to technical and program leadership.
Bachelor’s degree or equivalent experience.
U.S. citizenship required.
SECRET security clearance required.
