Principal Model-Based Systems Engineer

Accountabilities:

As a Principal Model-Based Systems Engineer, you will lead the adoption and implementation of rigorous MBSE practices, helping engineering teams deliver reliable, traceable, and well-integrated system architectures aligned with defense program requirements.

• Lead development programs through the systems engineering lifecycle using MBSE approaches that support Department of Defense digital engineering goals.

• Architect complex systems and guide multidisciplinary teams in applying structured systems engineering methods.

• Develop, maintain, and review SysML models using Cameo (MagicDraw) or comparable modeling tools.

• Establish and implement rigorous MBSE practices that maintain architectural integrity and traceability from requirements analysis through system and software development to production deployment.

• Customize and automate Cameo capabilities to support engineering workflows and enable compliance with digital engineering objectives across multiple programs.

• Integrate model-based requirements management and traceability with software development processes, including agile approaches where appropriate.

• Collaborate with domain experts, software engineers, and other technical stakeholders to translate program needs into effective system designs.

• Support the adoption of open architectures and modeling practices for software-intensive systems.

• Provide technical leadership, mentorship, and training to systems engineers, strengthening organizational expertise and improving modeling standards.

• Identify opportunities to improve systems engineering practices and demonstrate the value of MBSE through practical implementation.

• Contribute to advanced defense and national security programs involving sensors, cybersecurity, and other complex technical domains.

Requirements:

The ideal candidate is an experienced systems engineering leader with a strong background in digital engineering, systems architecture, and model-based methodologies, along with the ability to guide teams through complex technical development programs.

• Active U.S. Department of Defense Secret Security Clearance, with the ability to obtain a Top Secret clearance.

• U.S. citizenship, as required for government security clearance eligibility.

• Bachelor's, master's, or Ph.D. degree in Systems Engineering, Aerospace Engineering, or a related technical discipline.

• At least 10 years of professional experience in systems engineering or a related field.

• At least 5 years of experience working with SysML models in Cameo (MagicDraw) or a comparable modeling tool.

• Experience leading technical projects or engineering teams.

• Demonstrated experience applying MBSE methodologies to the development of Department of Defense systems.

• Strong understanding of systems engineering processes and the full systems development lifecycle.

• Experience working with software-intensive systems and open architectures.

• Ability to communicate complex engineering concepts, collaborate across disciplines, and mentor less experienced engineers.

Preferred qualifications:

• Active Top Secret Security Clearance.

• 10 or more years of experience architecting systems using modeling tools.

• Domain expertise in one or more of the following areas: radar, electronic warfare, acoustics, antenna apertures, sensor resource management, sea, air or space systems, large-scale platform test systems, cyber-physical systems, or open system architectures.

• Familiarity with government open architecture frameworks, such as Open Mission Systems, UCI, OMS, or COARPS.

• Proficiency in one or more high-level programming languages, including Java, C/C++, or Python.

• Experience with agile software development methodologies.

• Interest in advancing digital engineering practices and improving the integration of systems modeling with software development.

Benefits:

• Annual salary: $206,000–$284,000, depending on experience, education, training, critical skills, security clearance, and prevailing market and business conditions.

• Fully remote work arrangement.

• Opportunity to contribute to advanced research and development programs supporting defense, intelligence, and national security.

• Collaborative, technically challenging environment with opportunities to work alongside leading experts.

• Opportunities to mentor colleagues, share technical expertise, and help advance engineering practices.

• Support for continuous learning and professional growth.

• Equal employment opportunity and reasonable accommodations throughout the recruitment process.
