Our employees are not only part of history, they're making history. Northrop Grumman Space Systems is seeking a Systems Engineer – Level 3 or 4 with a focus on Model‑Based Systems Engineering (MBSE), located in Chandler, Arizona. The MBSE Systems Engineer is responsible for using Cameo to capture and maintain the system architecture and ensuring robust requirements traceability between the Cameo system model and the baseline requirements in DOORS. This role serves as a key integrator between traditional requirements‑based systems engineering and model‑based representations, enabling consistent, traceable, and analyzable system definitions. This position is 100% on site in Chandler, AZ. Salary Level 3: $98,400 - $147,600 Salary Level 4: $122,800 - $184,200 Key Responsibilities System Architecture Modeling (Cameo) * Develop and maintain system‑level and subsystem‑level models in Cameo, including structural, behavioral, and interface views. * Capture system functions, interfaces, states, and data flows in the model to reflect the authoritative system architecture. * Support architecture trade studies by representing alternatives in the model and coordinating with stakeholders to assess impacts. Requirements Traceability (Cameo ↔ DOORS) * Establish and maintain traceability between DOORS requirements and Cameo model elements (e.g., blocks, activities, interfaces). * Implement and maintain links, stereotypes, and relationships that support bidirectional traceability and impact analysis. * Regularly reconcile the Cameo model with the DOORS requirement baseline, ensuring consistency after requirement changes or model updates. Model & Requirements Integration * Collaborate with systems engineers and domain leads to ensure that the Cameo model accurately reflects allocated requirements, interfaces, and constraints. * Support definition and refinement of modeling conventions, naming standards, and modeling patterns to align with program and enterprise MBSE practices. * Generate model‑based views, reports, and dashboards (from Cameo) that support design reviews, requirements reviews, and stakeholder communication. Review & Configuration Support * Support technical reviews (e.g., SRR, PDR, CDR) by providing architecture views and traceability evidence from Cameo and DOORS. * Assist in the configuration management of the system model and associated requirement artifacts, ensuring proper version control and baselining. * Identify gaps, inconsistencies, or ambiguities in the architecture or requirements trace and propose corrective actions. Cross‑Team Collaboration & Training * Work closely with systems, software, and hardware teams to ensure model content supports their planning and analysis needs. * Provide guidance to other engineers on how to interpret and use the model and its traceability information. * Contribute to the continuous improvement of MBSE processes, tooling, and best practices on the program.
