What are the responsibilities and job description for the Senior MBSE Modeler position at Modern Technology Solutions, Inc.?
MTSI is seeking a Senior Model-Based Systems Engineering (MBSE) Modeler with expertise in SysML and Cameo Systems Modeler to support government and mission-focused digital engineering initiatives. In this role, you will lead MBSE model development across system-of-systems analysis, mission workflows, requirements modeling, architecture definition, and design verification. You will be responsible for delivering highquality Cameo-based system models, maintaining traceability across the Digital Thread, and ensuring modeling rigor aligned with DoW digital engineering objectives.
This role requires mature technical judgment and mastery of MBSE methods to support complex DoW systems and large-scale digital transformation efforts. Responsibilities Translate government technical direction into actionable MBSE modeling workflows and SysML model structures within Cameo. Lead the design, development, and maintenance of Cameo SysML models, ensuring coherence, completeness, and compliance with project standards.
Manage medium to largescale engineering tasks with a focus on integrating modeling activities across Digital Thread data, simulation tools, and engineering processes. Serve as the lead SysML modeler for mission engineering events, technical reviews, experiment planning, and integration activities requiring advanced MBSE expertise. Support integration and testing through the use of MBSE tools, including model execution, parametrics, and digital workflow automation.
Ensure timely delivery of MBSE artifacts, including model packages, viewpoints, architecture descriptions, and traceability analyses. Coordinate frequently with government technical representatives to align modeling products with mission requirements and system objectives. Mentor and guide junior engineers in MBSE best practices, SysML diagramming, Cameo usage, and model quality assurance.
Operate independently with minimal oversight while addressing highly complex modeling and engineering challenges. Required Skills Advanced proficiency with SysML, including structure, behavior, parametrics, and requirements modeling. Handson expertise with Cameo Systems Modeler, Teamwork Cloud, and model governance workflows.
Ability to translate complex customer needs into MBSE solution architectures, model structures, and executable system representations. Experience directing complex systems analyses, architecture studies, or mission workflows and expressing them in formal SysML models. Skilled in identifying optimal modeling approaches, defining modeling style guides, and allocating resources to support architecture development.
Strong communication skills and business acumen for interfacing with senior government customers. Demonstrated leadership in MBSEcentric technical initiatives, modeling committees, digital engineering proposals, and communities of practice. Commitment to innovation in digital engineering, including Digital Thread, Digital Twin, and enterprise modeling ecosystem development.
Qualifications U.S. Citizenship is required. Active Secret Clearance required
Bachelor's degree in an engineering discipline. At least 5 years of experience with significant involvement in model-based system design and analysis. Demonstrated ability to develop solutions for complex engineering challenges requiring in-depth analysis of both tangible and intangible factors.
Experience working within multidisciplinary teams of engineers, analysts, designers, and modelers. Knowledge of Digital Thread, Digital Twin, UAF, UML, SysML, and DoDAF concepts, with practical experience preferred. Strong written and verbal communication skills to collaborate and explain technical details to colleagues, management, and sponsors.
OCSMP certifications or equivalent MBSE credentials (desired). Clearance Ability to obtain a TS/SCI Clearance is desired. #LI-JJ1.
