Embark on a career putting innovative, reliable, and agile products and ideas into orbit and beyond. Northrop Grumman has opportunities waiting for you that play a vital role in human space exploration, national defense, and scientific discovery, supporting multiple programs across the universe. With us, you'll discover a culture of curiosity and collaboration that will have you Defining Possible from the day you start. Our space systems connect and protect millions of people on Earth every day, now and for the future. Explore your future and launch your career today.

This Systems Engineer role is located in Dulles, VA, supporting our National Security Space Systems programs that include technical roles at the mission, segment, and component levels. They span the entire program life cycle from early concept studies, design development, system integration/test, launch and early operations, mission operations/sustainment, and system disposal. Programs range from small feasibility studies to medium-sized on-orbit technology demonstrations and large-scale national systems. Successful candidates for this position will work in a technical role for a space program in Dulles, VA, in the National Security Space business area within the Tactical Space Systems Division. Model-Based Systems Engineering (MBSE) is gaining more visibility as the preferred systems engineering approach for space system architects and engineers within both industry and government. The selected candidate will be responsible for leading system modeling efforts performed by multi-disciplinary teams for complex, space- and ground-system development programs by maturing the descriptive system model & building a cadre of capable systems & software engineers that can perform their responsibilities “in the model”. This position utilizes abilities to interact in an organized and solutions-oriented manner, with external entities who are contributing elements of the integrated system. Duties:
  • Maintain and evolve program descriptive-system models, supporting program profiles/repositories (re-usable model libraries/patterns, design patterns, product architecture, and design-artifact templates) to enable efficient implementation of program model-based systems engineering efforts for a space-system development program.
  • Work closely with the program Lead Systems Engineer and Engineering Team Leads to ensure the system-architecture models are in sync with the system design & correct.
  • Model space-system architectures (functional and physical) at multiple levels of abstraction using Cameo Systems Modeler or Cameo Enterprise Architect to:
    • Develop the system’s Concept of Operations (ConOps), including mission threads and use cases, mission phases, and mission activities.
    • Define the functions at each architectural layer, trace them to the developing requirements, and trace them to the other architectural layers.
    • Define the physical implementation of alternative design solutions (capturing composition, interfaces, performance) and mature the selected design throughout development.
    • Capture the system verification and validation plan, map V&V activities to the system elements/requirements and support system V&V and customer buyoff.
    • Facilitate review by the program team, subject-matter experts, stakeholders, and customers throughout development (and operations, if applicable).
    • Exercise the models to perform impact assessments of proposed changes and support design decisions, and modify the model to capture approved changes as the design matures.
    • Support the Division MBSE Architect in developing domain-specific language (DSL) profile extensions to codify ontologies in various engineering and operations disciplines to reflect standards/best practices and enable seamless integration with other model-based applications.
    • NoVASpace

Basic Qualifications:
  • Bachelor’s degree in STEM (Science, Technology, Engineering, Math) or related area) and 9+ years of experience, Master’s Degree and 7+ years, or PhD and 4 years of experience. Preference for degrees in systems engineering and computer science.
  • Must have U.S. Citizenship with active or current Top Secret level security clearance.
  • Extensive experience with Systems Modeling Language (SysML) and Unified Modeling Language (UML), including experience with developing SysML profiles to extend the language for domain-specific purposes.
  • High proficiency with either Cameo Systems Modeler or Cameo Enterprise Architect
  • Strong systems engineering skills, including ConOps development, activity/scenario analysis, requirements definition/allocation, functional decomposition, interface definition, verification & validation, requirements traceability to the test plans, & life-cycle management.
  • Broad technical and MBSE experience, across multiple platforms, and encompassing the entire product development lifecycle.
Preferred Qualifications:
  • Experience with Unified Profile for DoDAF and MoDAF (UPDM), Unified Architecture Framework (UAF), and/or the Department of Defense Architecture Framework (DoDAF)
  • Experience with java, java script, python, OCL and/or groovy (in an MBSE context).
  • Experience with Velocity Template Language (VTL), Cameo Collaborator, and related methods for extracting information from the descriptive model by use of other software applications.
  • Experience with autocode-generation from Cameo/SysML models.
  • Experience with various technical analysis tools, such as MATLAB, STK, ModelCenter, etc.
  • Experience in all levels of space systems engineering at the mission-, vehicle-, and lower-levels of the system architecture.
  • U.S. Citizenship with Top Secret/SCI level clearance preferred.
