Damage Modeling Architect Principal Engineer P4; Onsite

What You Will Do

Hot Section Engineering (HSE) at Pratt & Whitney is seeking an experienced, 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.

• 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.

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

• 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.
