•

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.
