Our culture thrives on intellectual curiosity, cognitive diversity and bringing your whole self to work — and we have an insatiable drive to do what others think is impossible. Our employees are not only part of history, they're making history.

Northrop Grumman Space Systems—Missile Defense Integration offers an excellent opportunity for a Staff Systems Engineer (Lead) (26-499) to join our team of skilled and diverse professionals. Based in Colorado Springs, CO, or Huntsville, AL, this role is essential to supporting the U.S. President, the Secretary of Defense, and combatant commanders at the strategic, regional, and operational levels.

This position does not provide relocation assistance and requires on-site work with no remote options.

Position Overview

The Command and Control, Battle Management, and Communications (C2BMC) program is a key component of the Missile Defense System. It is a vital operational system that enables the U.S. President, the Secretary of Defense, and combatant commanders at strategic, regional, and operational levels to plan ballistic missile defense operations systematically, collectively monitor the battle, and dynamically control networked sensors and weapon systems to achieve global and regional mission goals. C2BMC supports layered missile defense capabilities that enable an optimized response to threats across all ranges and flight phases. It serves as a force multiplier by networking, integrating, and synchronizing autonomous sensor and weapon systems and operations, both globally and regionally, to improve performance. C2BMC is essential for all ground and flight tests that verify and demonstrate the current and future capabilities of missile defense systems.

Essential Functions

• Lead and mentor a regional systems engineering team (~30 junior and senior engineers) while continuing to execute core engineering tasks, including capability concepts, modeling, analysis, test support, and requirement verification

• Set technical priorities for the regional SE team, create and review capability concepts, and conduct rigorous technical reviews to ensure high-quality engineering products

• Remain “hands-on” by actively producing and reviewing key engineering artifacts, including requirements, architecture views, and interface documentation

• Demonstrated leadership of multidisciplinary engineering teams while remaining actively engaged in technical work

• Strong track record of delivering decomposed, traceable requirements linked to a validated system architecture for large-scale defense programs

• Experience with regional C2BMC implementations, including sensor management, tasking, cueing, and discrimination, as well as an understanding of BMDS operational constraints and environments

• Proven ability to collaborate directly with multiple customer and contractor organizations (government, DoD, industry) in a complex, multi-stakeholder environment

• Excellent written and oral communication skills, with the ability to translate model-based analyses into clear, actionable recommendations for senior leaders and operators

• Ability and willingness to travel occasionally to support program and customer needs

Basic Qualifications

##

Please list your current security clearance and IAT or relevant certifications on your resume, if applicable.

##

• A Bachelor’s Degree in STEM Computer Science, Systems Engineering, Software Engineering, Project Management, Mathematics, Physics, or a related field from an accredited university, along with 12 years of experience; or a Master’s degree (preferred) in a STEM -related field with 10 years of relevant work experience; or a PhD in a related discipline with 8 years of relevant work experience

• Applicants must have a current, active Government-Issued 8140 certification at IAT Level II or higher (such as Security+ CE, CISSP, CCNA-Security, CySA+, CND, etc.) at the time of application, which is required to start. The candidate is responsible for maintaining their 8140 certifications throughout the entire contract period

• Applicants must have a current, active in-scope Government-issued Secret security clearance at the time of application, which is required to start

• Extensive systems engineering background with hands-on MBSE experience ( SysML/UML modeling , requirement decomposition, architecture development) within missile defense or other high-complexity, mission-critical domains

Model-Based Requirement Decomposition

• Lead the systematic breakdown of high-level operational needs into traceable, hierarchical system and interface requirements linked directly to architectural elements

• Capture warfighter, operator, and stakeholder intent in a model-based repository (e.g., DOORS Next, Jama Connect ) and maintain a single source of truth

• Perform functional decomposition using SysML Use Case and Activity diagrams to derive system-level functions, sub-functions, and allocated capabilities

• Decompose functional requirements into hierarchical, traceable low-level system and interface requirements; link each low-level requirement to the originating stakeholder need and to the relevant architectural element

• Maintain bidirectional traceability (needs, functional requirements, logical and physical requirements, and verification) throughout the product lifecycle; use model queries to assess the impact of changes automatically

• Facilitate requirement workshops with customers and subject matter experts to validate decomposed requirements and capture clear acceptance criteria

Architecture Development & Management

• Lead SE teams in creating, validating, and maintaining robust, model-based system architecture that supports regional C2BMC functional and performance objectives

• Develop coherent logical and physical architectures using SysML Block Definition Diagrams (BDD), Internal Block Diagrams (IBD), and parametric diagrams as needed

• Define subsystem boundaries, interfaces, and data flows that support regional C2BMC functions such as sensor management, cueing, tasking, and discrimination

• Create architecture viewpoints (operational, systems, services, allocation, behavior) aligned with DoDAF and UAF standards to communicate design intent to diverse audiences clearly

• Perform architecture trade studies (e.g., performance, cost, risk, survivability) within the model environment and generate quantitative results (timing, bandwidth, processing load) that feed back into requirement refinement

• Validate architectural compliance with C2BMC operational concepts and regional constraints (latency, bandwidth, threat environment) using model-based simulation and analysis tools (e.g., MATLAB/Simulink, STK , or integrated SysML simulation environments)

Model-Based Analyses & Verification

• Lead the team in conducting trade studies and reliability assessments directly from the system model

• Partner with Integration and Test teams to generate model-derived test cases and automate verification of requirement satisfaction against the model

• Analyze test results, update models to reflect observed behavior, and close the verification loop to ensure accurate, current digital representations of the system

Interface Control & Management

• Direct the d
