Mechanical Integrity Engineer – Gas Turbine Structures

Quest Defense Systems & Solutions is seeking a Mechanical Engineer, Integrity/Structures, to support structural analysis and substantiation work for gas turbine engine components. The role involves using finite element analysis and collaboration with engineering teams to evaluate designs and provide analysis-backed recommendations.

Responsibilities:

• Perform structural and mechanical integrity analysis for gas turbine engine components and systems
• Use finite element analysis (FEA) and hand calculations to support design decisions, technical substantiation, and customer requirements
• Evaluate component durability, strength, low-cycle fatigue, fatigue life, and fracture mechanics considerations
• Build, modify, and analyze models using CAE tools such as ANSYS Classic, ANSYS Workbench, Siemens Simcenter, Nastran/Patran, and ABAQUS
• Support geometry and mesh preparation for analysis activities, including working with Siemens Simcenter and Siemens NX when needed
• Review analysis results, identify risks or areas of concern, and provide clear technical recommendations
• Participate in technical reviews, program reviews, and customer discussions to communicate analysis findings and support engineering decisions
• Collaborate with internal engineering teams, customer stakeholders, and cross-functional groups to solve complex structural/mechanical challenges
• Document analysis plans, assumptions, methods, results, and conclusions in accordance with customer and program requirements
• Prepare technical reports and presentations that clearly communicate findings, substantiation, and next steps
• Manage multiple tasks and deadlines while supporting changing program priorities

Requirements:

• Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or a related engineering discipline from an accredited university
• 2+ years of experience in gas turbine structural analysis, mechanical integrity, durability, or related aerospace structures work
• Strong understanding of low-cycle fatigue, fatigue life, fracture mechanics, strength, and durability principles
• Experience using finite element analysis and/or hand calculations to support structural or mechanical design decisions
• Working knowledge of CAE tools such as ANSYS Classic, ANSYS Workbench, Siemens Simcenter, Nastran/Patran, ABAQUS, or similar analysis tools
• Ability to document analysis plans, assumptions, methods, results, and conclusions in a clear and organized manner
• Strong written and verbal communication skills, with the ability to explain technical findings to engineering teams, managers, and customer stakeholders
• Ability to work collaboratively in a cross-functional engineering environment
• Must be a U.S. Citizen due to the nature of the work
• Experience supporting gas turbine engine components, aerospace propulsion systems, or rotating machinery
• Hands-on experience with geometry cleanup, mesh preparation, model setup, analysis, and post-processing
• Proficiency with Siemens Simcenter, Siemens NX, ANSYS Classic, ANSYS Workbench, Nastran/Patran, ABAQUS, HEEDS, or similar tools
• Experience evaluating strength, fatigue, durability, low-cycle fatigue, crack growth, or fracture mechanics of metallic components
• Familiarity with aerospace materials, manufacturing processes, part standards, and design practices
• Ability to translate analysis results into clear technical recommendations, reports, and customer-ready presentations
• Experience participating in technical reviews, design reviews, program reviews, or customer-facing engineering discussions
• Strong time management skills with the ability to support multiple priorities, meet deadlines, and work effectively in a remote or hybrid team environment
• Demonstrated ability to collaborate across engineering disciplines, including design, analysis, manufacturing, program, and customer teams
