Principal Engineer Systems - Fault Management and System Autonomy

At 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 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.
Successful candidates for this position will work in a technical role fora spaceprogram in Dulles, VA in the NSS business area within the Space Systems Group.

Fault Management and System Autonomy (FMSA) job responsibilities include:

  • Develop and apply FMSA policies, practices, requirements, plans and schedules
  • Establish and guide the requirements/principles/practices for the architecture, design and implementation of all FMSA products.
  • Establish and guide the FMSA requirements/principles/practices for the integrated verification and validation (via both analysis and test) of all FMSA products.
  • Develop the system Concept of Operations (ConOps), including the identification of mission phases, system-level activities, mission/vehicle/module/subsystem states and modes, and system threads (scenarios), with particular focus on the fault management and system autonomy philosophy to be applied in each phase/activity/mode to best meet stakeholder objectives, requirements, and goals.
  • Interpret mission/system requirements and ConOps, customer specifications, and applicable industry standards to develop appropriate FMSA requirements at each layer of the system architecture. This includes fault tolerance requirements for mission objectives, mission- and safety critical functions, and critical sequences.
  • Perform a wide variety of FMSA analysis tasks, including generation and/or rigorous review of functional analysis, activity analysis, timeline analysis, fault tolerance analysis, fault trees, functional risk/hazard analysis, fault interaction analysis, fault dynamics analysis, common-mode analysis, FMEA/FMECA, software system safety analysis, system/subsystem hazard analysis, fishbone/root-cause analysis, reliability analysis.
  • Based on these analyses, develop the FMSA architecture, and identify/deploy appropriate autonomy and failure mitigation strategies (prevention, tolerance and resilience) to best meet the program needs.
  • Develop and execute system-level tests and simulations to verify FMSA requirements and validate expected system behavior. This will include the identification of needed capabilities for test-bed/simulator platforms, development of test scenarios to support comprehensive system-level V&V, writing of test procedures and scripts, executing tests and simulations, and writing test reports.
  • Evaluate Engineering Change Proposals, perform impact analyses (including schedule and cost estimates), and formulate recommendations for consideration by program management.
  • Identify opportunities for improvement based on review of failure data from both ground tests & simulations and flight operations, and support development and implementation of system design improvements.
  • Work closely with System Safety engineering to identify & analyze hazards, develop & implement appropriate hazard controls, and follow-through to ensure controls are appropriately implemented in training, designs, procurement, manufacturing, assembly, test, storage, and hazardous operations by personnel supporting assigned programs
  • Apply FMSA engineering principles to assess design compliance of complex aerospace systems and synthesize rationale and justification for waiver requests and product non-compliances.
  • Conduct system-level analyses to architect/design next-generation mission concepts (satellite servicing, space logistics, etc.) to maximize mission success without compromising compliance with customer, government and internal flight safety requirements.


Basic Qualifications:
This position requires a BS degree in Engineering or related technical field and at least 5 years of applicable experience, or an MS degree and 3 years of applicable experience.

Must have U.S. Citizenship with current or active Top Secret level Clearance.

Preferred Qualifications:

Fault management systems engineering experience.
