Principal / Sr. Principal Mechanical Analysis Engineer
About The Position
Northrop Grumman Mission Systems is hiring a Principal or Senior Principal Mechanical Analysis Engineer for its Engineering and Sciences organization in Woodland Hills, California. The role supports senior mechanical engineers in designing military avionics, including inertial navigation and measurement systems and mission computers for the Sentinel program. The position is 100% on-site and is not eligible for remote work; relocation assistance may be available. The engineer will contribute to the organization’s enterprise-wide digital transformation using model-based engineering and agile practices, within a collaborative, team-oriented environment focused on continuous learning and automation. The engineer serves as a technical individual contributor on the Analysis Engineering Team. Work includes assessing structural viability for certification; conducting structural analyses of metallic structures, mechanical and electromechanical systems, and equipment; building and manipulating finite element models; reviewing drawings and material and structural requirements; calculating margins; documenting analysis methods; and supporting structural test planning, design reviews, material review boards, and nonconformance dispositions. Analyses may be performed by hand and with program-approved automated methods. The position may be filled at either the Principal or Senior Principal level. The standard work schedule is 9/80, with nine-hour days Monday through Thursday and every other Friday off. Travel is 10% of the time. An active U.S. Government Secret clearance and U.S. citizenship are required.
Requirements

- U.S. citizenship.
- Active U.S. Government Secret clearance.
- Experience developing finite element analysis (FEA) models and conducting analyses in ANSYS.
- Experience in at least three of the following: system/subsystem FEA modeling or analysis, piece parts, static analysis, modal analysis, buckling, dynamic analysis (sine, random, or acoustic), thermal strength or distortion, and bolted-joint analysis.
- Ability to verify simulation results using hand calculations and/or comparison with heritage programs, and to perform bolted-joint analyses.
- Ability to work on site in Woodland Hills, California.
- Background in loads development, preliminary and detailed design, static analysis, FEA, damage tolerance and durability, fatigue, bolted and bonded interfaces, repair, structural testing, and in-service modifications, repairs, and extensions.
- Ability to collaborate in a team environment, prioritize and adjust tasks, manage multiple responsibilities, and analyze complex problems and develop solutions.
