Job Description:
Senior Gas Turbine Performance Engineer: AI Accelerated Engineering
Why this role
If you love the rigor of thermodynamics and the satisfaction of making models match reality, and you’re excited about using modern AI tools to amplify engineering impact, this role is built for you. You’ll sit at the crossroads of engine physics, product decisions, and real operating data, building performance models and software that influence everything from new product definition to test cell execution to fielded fleet operations.
What the Performance Group does
The Gas Turbine Performance Group leads concept and advanced cycle studies and delivers calibrated performance predictions for new and upgraded engines. We oversee performance during engine development, support production and acceptance testing, and enable product support teams worldwide with the tools needed to analyze, predict, and guarantee engine performance.
A core part of our mission is building and maintaining the ecosystem (models, workflows, automation, and data pipelines) that turns thermodynamics, test, and field data into decisions. Increasingly, our transient cycle models and calibrated physics tools are the foundation for AI enabled digital twins, unlocking longer service intervals, better cycle count capability, and improved efficiency through operational flexibility.
What you will do
Turn data into engineering decisions.
Analyze acceptance test and fleet/field datasets to trend performance, troubleshoot issues, and monitor aeromechanical/operability behavior across product lines.
Own high-stakes performance predictions.
Build, calibrate, and defend steady state and transient performance models for new products, upgrades, and investigations, where accuracy matters and assumptions must be explicit.
Build the tools engineers rely on.
Develop and maintain the internal software used across design, sales/applications, customer services, overhaul, and customer sites, improving usability, automation, traceability, and confidence in results.
Accelerate engineering with AI.
Apply modern AI techniques:
- speeding up calibration and uncertainty exploration,
- enabling anomaly detection and diagnostics,
- creating reducedorder models that stay grounded in physics,
- supporting digital twin workflows using physicsguided learning approaches.
Collaborate across disciplines.
Work shoulder to shoulder with design, controls, test, operations, and digital teams to solve urgent problems quickly while also building long term capability.
What youll love about the work
- Physics first engineering with direct line of sight to real hardware and customer outcomes.
- High leverage: your models and tools scale across programs, teams, and global sites.
- A modern toolchain mindset: automation, reproducibility, and AI assisted workflows are part of the job, not a hobby.
What you will bring (required)
- B.S. / B.Eng. in Mechanical or Aerospace Engineering (or closely related field) plus experience with multiple design cycles within industry and performance engineering to real world problems.
- Foundation of knowledge for growth in gas turbine performance and thermodynamics (cycles, maps, matching, operability concepts, off-design behavior).
- Ability to work through ambiguity, manage priorities, and deliver high-quality results under schedule pressure.
- Clear written and verbal communication. You can explain assumptions, results, and risks to both technical and nontechnical partners.
- Proven habit of finishing work with thoroughness and reliability (validation, documentation, and follow-through).
What sets top candidates apart (preferred)
- Applicable experience in gas turbine performance, aerodynamics, instrumentation, real world testing or closely related area.
- Applied knowledge of model calibration and troubleshooting of gas turbine performance/operability in steady state and/or transient.
- Strong engineering software skills, building scripts, code, or automation that makes other engineers faster and improves quality.
- Familiarity with controls and control logic and controls software.
Tools & technologies (typical, not exhaustive)
- 1D multiphysics engine performance tools (e.g., NPSS, PROOSIS, GasTurb, pyCycle or similar)
- Programming/scripting: Python (strongly preferred), and/or C/C++/C#/Fortran/VBA
- Engineering computing: MATLAB / Simulink
- Analytics & visualization: Tableau (or similar), plus modern data tooling as applicable
- Standard productivity tools (Microsoft Office suite)
