Damage Modeling Architect Principal Engineer P4 (Onsite)

Damage Mechanism Lead

At RTX, the world largest aerospace and defense company, 185,000 great minds are united by purpose and inspired to make a difference solving the world's most complex problems. With our three market leading businesses, world-class operations and investments in research and development, we offer capabilities and opportunity no one else can. Together, we push the boundaries of known science and find new ways to connect and protect our world.

Pratt & Whitney is a world leader in the design, manufacture and service of aircraft engines and auxiliary power systems and has been revolutionizing modern flight for over 100 years. Join us and help shape the future of aerospace and defense.

Only candidates internal to Pratt & Whitney Engineering will be considered for this role.

What You Will Do:

Hot Section Engineering (HSE) at Pratt & Whitney is seeking an experienced and self?motivated individual to join our HSE Core Durability group as the Damage Mechanism Lead supporting improvement of the Durability Design System (DDS). DDS enables durability?focused designs and thermal analyses for turbine airfoils, blade?outer?air?seals (BOAS), and combustor components. The ideal candidate will possess strong analytical skills, deep understanding of hot?section damage mechanisms (including creep, thermo?mechanical fatigue, CMAS infiltration, and coating spallation), and experience in solid and fracture mechanics. A major deliverable is the development of reduced?order models for critical damage mechanisms and their implementation into DDS to improve hot?section lifing predictions. The role also includes formalizing processes and documentation to ensure consistency and traceability across durability tools. Close collaboration is expected with Materials and Process Engineering (MPE), as well as external research partners, to advance modeling capabilities, validate mechanisms, and integrate new material data. Familiarity with geometry creation and morphing in Siemens NX is valued for supporting tool development and model integration.

Key Responsibilities :

• Develop physics?based models for creep, thermo?mechanical fatigue, CMAS infiltration, and thermal barrier coating spallation.
• Apply solid and fracture mechanics principles to improve durability predictions and reduced?order damage models.
• Create and formalize processes, workflows, and documentation for durability modeling, integration, and validation.
• Coordinate with MPE to define material testing needs and support data interpretation.
• Develop reduced?order models to be incorporated into hot?section lifing tools and DDS.
• Support geometry creation, manipulation, and morphing in NX to enable consistent model setup and tool workflows.
• Advocate for and coordinate university research efforts; oversee relevant data collection to support mechanism development.
• Benchmark emerging research, modeling techniques, and material characterization relevant to gas turbine damage mechanisms.

Qualifications You Must Have:

• Bachelor's degree in Science, Technology, Engineering or Mathematics (STEM)
• 8 years of engineering experience, or an Advanced degree in a related field and 5 years of related engineering experience.

Qualifications We Prefer:

• Advanced degree in Mechanical Engineering or Material Science.
• Understanding of damage mechanisms associated with turbine hardware.
• Experience with solid mechanics and fracture mechanics
• Experience with geometry operations within NX.
