Northrop Grumman Innovation Systems designs, builds and delivers space, defense and aviation-related systems to customers around the world. Our main products include launch vehicles and related propulsion systems; missile products, subsystems and defense electronics; precision weapons, armament systems and ammunition; satellites and associated space components and services; and advanced aerospace structures.

System Safety Engineering utilizes System engineering processes and tools to drive the overall system design to meet Safety requirements to minimize the risk inherent in launch vehicle operations while maximizing mission reliability and success. At Northrop Grumman Launch Vehicles Division, System Safety Engineering is involved in all phases of a program life cycle, from proposal generation to launch operations. System Safety Engineering interfaces with the various Ranges to ensure that our launch vehicles meet safety requirements while providing high reliability to the customer.

The Lead System Safety Engineer is responsible for leading a System Safety Engineering team that will develop key deliverables, and support system safety activities including ground safety, range safety and flight safety throughout the OmegA program life cycle. The System Safety Engineering deliverables are the only documents that provide a complete, true system description of the components, systems, launch vehicle and mission design, and as such require a high level of understanding of the entire design.  The System Safety Engineering effort includes interacting as part of a multi-disciplined engineering team to develop the launch system architecture and constituent elements for new and existing flight programs, as well as new business concepts and proposals. This position may include launch campaign support at remote launch sites.


  • Interact  with key internal and external customers and partners on a daily basis (30th  and 45th Space Wings, FAA, Aerospace, KSC Site Safety).
  • Lead a small team of System Safety engineers in defining, implementing and verifying System Safety requirements to ensure that the inherent risks are mitigated.
  • System Safety Engineers are responsible for understanding the entire mission, including the launch vehicle, payload, ground support equipment, range infrastructure and range safety interfaces.
  • System Safety Engineers are expected to understand how the different components, subsystems, systems and integrated launch vehicle function and interact, with a focus on System Safety.
  • Apply the systems engineering process to define and verify launch vehicle and ground support equipment requirements to ensure safe operations and conduct system safety analyses to architect and implement a safe and      robust system.
  • Define and verify launch vehicle-to-payload interface requirements and support space vehicle launch campaign management activities at both Cape Canaveral and Vandenberg AFB (VAFB) launch sites. 
  • Manage interface with customer safety and launch integration personnel (US Air Force, NASA, etc.), and support ground operations and launch mission working groups.
  • Support launch vehicle design and development to ensure that customer and internal goals for safety, mission success, and performance are met.
  • Analyze Integration and Test processes to demonstrate customer and internal requirements are met for both safety and mission success, whether at the launch site (KSC and VAFB), or at our facilities in Chandler, AZ.
  • Conduct system level analyses to architect and design next generation mission concepts to maximize mission success without compromising compliance with customer, government and internal flight safety requirements.
  • Describe, analyze and explain launch vehicle designs to External customers to explain how applicable safety requirements for design, build, and test are met.



  • Bachelor’s degree or higher in an Engineering or related field (or equivalent experience).
  • 10+ years of experience.
  • Experience with launch vehicle system design, testing or Mission Operations.
  • Exposure to the systems engineering discipline and its application for system safety.
