RELOCATION ASSISTANCE: No relocation assistance availableCLEARANCE REQUIRED FOR START: YesCLEARANCE TYPE: SecretTRAVEL: Yes, 10% of the TimeDescriptionAt Northrop Grumman, our employees have incredible opportunities to work on revolutionary systems that impact people's lives around the world today, and for generations to come. Our pioneering and inventive spirit has enabled us to be at the forefront of many technological advancements in our nation's history - from the first flight across the Atlantic Ocean, to stealth bombers, to landing on the moon. We look for people who have bold new ideas, courage and a pioneering spirit to join forces to invent the future, and have fun along the way. 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 verificationSet technical priorities for the regional SE team, create and review capability concepts, and conduct rigorous technical reviews to ensure high-quality engineering productsRemain “hands-on” by actively producing and reviewing key engineering artifacts, including requirements, architecture views, and interface documentationDemonstrated leadership of multidisciplinary engineering teams while remaining actively engaged in technical workStrong track record of delivering decomposed, traceable requirements linked to a validated system architecture for large-scale defense programsExperience with regional C2BMC implementations, including sensor management, tasking, cueing, and discrimination, as well as an understanding of BMDS operational constraints and environmentsProven ability to collaborate directly with multiple customer and contractor organizations (government, DoD, industry) in a complex, multi-stakeholder environmentExcellent written and oral communication skills, with the ability to translate model-based analyses into clear, actionable recommendations for senior leaders and operatorsAbility and willingness to travel occasionally to support program and customer needsBasic 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 experienceApplicants 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.
