About The Position

In the Lead Propulsion Modeling & Simulation Engineer role, you will be an integral part of the Future of Flight Performance and Operability team supporting GE Aerospace’s next generation of commercial propulsions systems. You will work across both novel and derivative engine architectures, helping to define concepts that drive performance, efficiency, and sustainability for future products. This role focuses on supporting the aerothermal component and propulsion system modeling necessary to support Preliminary Design, Steady-State Performance, Transient Analysis, Operability, Controls, and other disciplines. You will have a chance to further grow your technical and leadership skills, while influencing the direction of the Performance Methods team. The primary focus of this position is to develop, enhance, and maintain NPSS-based thermal cycle models for next generation engine concepts. You will: • Build and refine analytical NPSS thermal models for emerging engine architectures • Diagnose and resolve model issues, ensuring robustness, stability, and fidelity • Optimize model structure and code for speed, usability, and scalability • Create and document modeling approaches that can be reused across programs This role is ideal for an engineer who enjoys hands-on modeling, solving complex system level problems, and translating analysis into strategic recommendations that directly impact the future of commercial aviation.

Responsibilities

• Developing physics-based aerothermal system models that behave reasonably throughout the operational envelope.
• Resolving model issues through understanding both the physical system, the modeling that represents it, as well as the numerical iteration methods used to solve the system.
• Packaging models for delivery to customers and integration into rigs or simulators.
• Creating, developing, and integrating aerothermal models of individual components, physical processes, and subsystem models, that constitute an overall system model.
• Leading design reviews of modeling approach, functionality, and validity.
• Executing and assisting others with the analysis / evaluation of assigned projects that meet business standards, practices and procedures and the product / program requirements.
• Assuring proper documentation of technical data generated for the assigned projects and/or tasks consistent with engineering policies and procedures.
• Interfacing with tool organizations and commercial teams to improve and standardize processes such as data reduction and class code development.
• Managing and communicating project status, business issues and significant developments.
• Participating as a presenter and reviewer in technical and program reviews.
• Actively supporting the Performance Technical Community and Design Board.
• Leading strategic initiatives and aligning efforts to FLIGHT DECK.
