Additionally, your responsibilities will include:
- Lead programs & projects working with internal & external customers to create propulsion solutions for the next generation of aircraft across a wide range of commercial products, including business, regional, narrow-body, and wide-body aircraft.
- Build, optimize & execute aero-thermal models of new concept & derivative engines, aligning input from component design teams to customer requirements.
- Partner with Preliminary Mechanical Design engineers to build multidisciplinary design optimization (MDO)
- Coordinate with a cross-functional team of adjacent disciplines (aero, mechanical, systems) to assess technology capability & maturity in support of business objectives.
- Communicate with leadership to help shape the future propulsion strategy.
- Execute the analysis and evaluation of assigned projects that meet business standards, practices and procedures, and the product or program requirements.
- Ensure proper documentation of models developed for the assigned projects and tasks consistent with engineering policies and procedures.
- Provide timely communications on significant issues or developments to program and engineering leadership.
- Participate in organizational efforts in assigned projects and tasks including establishment of processes and best practices.
- Participate as a presenter or reviewer in technical and program reviews across engine programs.
- Lead the GE Aviation cultural transformation coaching and mentoring, fostering inclusive environments, and driving a systematic approach to Lean.
