What You Will Do:

The Hot Section Engineering Mechanical Design team is seeking an experienced Senior Principal Mechanical Engineer, preferably with turbo machinery experience. If you have relevant mechanical design background and experience in these areas and possess the skills and motivation to bring new ideas into practice, we would like to like to hear from you.

The mechanical designer will work with the other disciplines of the Integrated Product Team (IPT) including project, structures, durability, aero-thermal, and product definition. The mechanical designer will also need to interface with other Hot Section Engineering IPTs as well as other departments such as Customer Technical Support, Global Services Engineering, and Product Safety, Certification and Validation & Development Operations to complete these tasks.

The candidate could work either commercial or military programs, which will be determined based upon candidate qualifications and program needs. Depending on the phase of the program, the tasks will vary, but may include clean sheet design, delivering development hardware to test engines, facilitating the delivery of hardware to production engines, processing engineering changes to improve the production configuration, and support of fielded engines.

Key Responsibilities:

• Resolution of mechanical engineering problems of difficult and complex scope, seeking a balanced system solution, ensuring engineering excellence, all with some supervisor oversight.
• Review and approval of product definition data (prints and models).
• Generate development hardware design solutions that meet the objectives of the test engines and facilitate the delivery of the development hardware to the test engines on schedule.
• Work with Operations to address production issues and evaluate hardware nonconformances to facilitate the timely delivery of production hardware.
• Process technically sound engineering changes within program schedule that meet performance metrics such as cost, weight, and part life.
• Work with our Customer Technical Support (CTS) team to respond to customer questions, review deteriorated hardware, and update engine maintenance manual limits.
• Utilize standard work and CORE/ACE tools to continuously improve the design process.

Qualifications You Must Have:

• Bachelor of Science in Science, Technology, Engineering or Mathematics (STEM)
• 10 years of engineering experience or 7 years of experience with an advanced degree
