Standard Job Description
Analyzes, researches, and develops structural engineering specifications involving metals, non-metallic or composite structural materials for product design, or operation of product to include structures, mechanical, hydraulic, electrical and electronics, power plant, armament, heating and ventilating, equipment, and maintenance designs. Analyzes damage tolerance, durability, design allowables, and structural modeling. Specific structural engineering specialties may include dynamics and loads, stability, stress, fatigue, and thermal analysis. Tools utilized may include CATIA, IDEAS, ProEngineer, and a variety of software applications.
About The Role
The Structural Integrity Engineer (SIE) is a senior technical specialist who analyzes, develops, and validates the mechanical integrity of complex structural systems across light-weight and heavy-weight platforms. The role encompasses metallic, non-metallic, and composite materials, covering design, production, testing, and maintenance phases. Core responsibilities include damage-tolerance, durability, and structural modeling across dynamics, loads, stability, stress, fatigue, and thermal analyses. The duty cycle uses a broad array of engineering tools, notably MSC Nastran, MSC Marc, Siemens Simcenter, Beta CAE, ANSA, and PTC Creo.
