• Collaborate effectively with cross-functional teams and demonstrate a strong understanding of related disciplines, including Controls, Thermals, Air Systems, Lifing, and Design, to ensure integrated and optimized propulsion system solutions.
• Solve complex and unique performance challenges to drive product improvement.

Basic Requirements:

• Bachelor`s degree in Engineering, Physics or Mathematics with 5+ years experience in thermodynamics, gas dynamics, fluid mechanics and/or engine design
• A Master`s degree in Engineering, Physics or Mathematics with 3+ years experience in thermodynamics, gas dynamics, fluid mechanics and/or engine design OR;
• A PhD in Engineering, Physics or Mathematics
• Eligible to obtain and maintain security clearance (requires USA citizenship).

Preferred Requirements:

• Expertise in computer programming language such as NPSS, Python, Fortran, C++, MATLAB, etc.
• Demonstrated technical leadership to delivery in complex project with ambiguity
• Demonstrated expertise in gas turbine engine steady-state performance, transient performance, engine operability, or data systems for performance.
• Industry Leading Expertise in the performance-related support of the design and/or development of gas turbines
• Experience in simulation/modeling of gas turbine cycles, hybrid electric systems, cycle analysis, engine operability, sizing, and/or preliminary design analysis.
• NPSS Expertise in multiple thermodynamic cycle models
• Experience with transient performance, including stability margin accounting and operability test planning and analysis for multiple engine programs
• Ability to define and detail functional data for design and follow design iteration processes.
• Authoritative knowledge in robust design techniques and visualization including statistical software such as JMP and Python
