At PMAT, we work on mission critical systems that directly support the warfighter, designing, building, and securing modern digital capabilities across cloud, data, and software environments. Our teams tackle complex, real-world challenges where delivery matters more than theory, and innovation is driven by curiosity, collaboration, and purpose.

In this role, you’ll support the design, development, integration, and verification of complex systems in support of defense and national security missions.

About the role: 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. This role will help establish and maintain standardized architecture development processes, governance frameworks, data structures, and modeling practices that enable consistent engineering and informed decision-making across the organization. The candidate 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. The role requires strong systems engineering fundamentals, expertise in model-based methodologies, and the ability to translate operational requirements into structured architectures, data models, and actionable engineering insights supporting capability development, integration, and sustainment.

Responsibilities:

Systems Engineering & Architecture

-





- Apply systems engineering principles and lifecycle processes consistent with ISO/IEC/IEEE 15288 and industry best practices.

- Develop and maintain system architectures, functional decompositions, technical baselines, and engineering specifications.

- Translate stakeholder and mission needs into clear system requirements, functional architectures, and technical solutions.

- Develop and maintain system models using Cameo Systems Modeler, MagicDraw, Enterprise Architect, or equivalent MBSE tools.

- Apply Systems Modeling Language (SysML) and architecture frameworks such as DoDAF and UAF to represent system structure, behavior, interfaces, and constraints.

- Develop and maintain engineering documentation, including System Requirements Specifications (SRS), Systems Engineering Management Plans (SEMP), Interface Control Documents (ICDs), and Concepts of Operations (CONOPS).

Requirements Engineering & Traceability

-

- Support requirements development, analysis, decomposition, allocation, validation, and change management.

- Establish and maintain bidirectional traceability among stakeholder needs, system requirements, architecture elements, interfaces, and verification artifacts.

- Develop measurable, testable,



and verifiable system and subsystem requirements.

- Use requirements management tools such as DOORS, Jama, Jira, or equivalent platforms.

- Maintain Requirements Verification Traceability Matrices (RVTM) and assess the technical impacts of requirements changes.

- Support requirements reviews and technical baseline management.

Model-Based Engineering, Analysis & Simulation

-

- Develop and maintain system models to support engineering analysis, design decisions, and program execution.

- Create functional, behavioral, structural, and parametric models to evaluate system performance and operational scenarios.

- Apply MBSE methodologies to support trade studies, simulation, design alternatives, and technical risk assessments.

- Support the definition and evaluation of Key Performance Parameters (KPPs), Measures of Performance (MOPs), Measures of Effectiveness (MOEs), and Technical Performance Measures (TPMs).

- Integrate system models with simulation environments and other engineering analysis tools.

- Ensure models remain aligned with approved requirements, architectures, and technical baselines.

System Integration, Interfaces & Verification

-

- Support system integration planning, interface definition, and interoperability assessments.

- Develop and maintain interface requirements, interface definitions, and ICDs.

- Collaborate with software, hardware, cybersecurity, and integration teams to identify and resolve technical dependencies.

- Support verification and
