Lead Thermodynamic Performance Engineer

About the role

We are seeking a Senior Thermodynamic Performance Engineer to lead the analysis, prediction, and optimization of engine thermodynamic performance across the full operating envelope. In this role, you will be a technical leader for cycle performance, fuel efficiency, and operating margins, partnering closely with design, controls, test, and services teams.

Responsibilities

• Develop and own cycle and performance models (steady-state and transient) for engines across the operating envelope
• Predict thrust/power, fuel flow, temperatures, pressures, and margins versus altitude, Mach, and mission conditions
• Plan and support engine performance testing, including defining test matrices and key performance points
• Correlate test data to models, perform uncertainty analysis, and update maps/models based on results
• Create and refine component maps and limits (fan/compressor/turbine maps, operating lines, surge and temperature margins)
• Collaborate with controls engineers on schedules (VGV, bleeds, fuel flow) to balance performance, operability, and hardware life
• Analyze fleet and in-service performance data to identify trends, degradation, and improvement opportunities
• Lead performance trade studies and optimization for efficiency, fuel burn, and operating margins
• Support certification and customer programs with validated performance data and technical justifications
• Provide technical leadership and mentoring to junior engineers and drive best practices in thermodynamic performance
• Work cross-functionally with design, aero, mechanical, systems, test, and services teams to ensure performance requirements are met
• Improve gas turbine thermodynamic and operability modeling techniques
• Engage in research, design, development, and enhancement of technologies to improve performance, operability, and cost
• Document technical data and results in accordance with engineering policies and procedures
• Communicate significant technical issues, risks, or developments in a timely manner
• Participate in organizational initiatives and technical/program reviews
• Support technical program managers and mentor less experienced engineers
• Make decisions within a defined framework and engage senior team members on complex issues
• Contribute independently to projects while supporting senior engineers in advancing performance related technologies
