Pratt & Whitney is seeking an Intern - Externals Design to support our Mechanical Systems, Externals, & Nacelles (MSEN) Engineering organization through execution of design tasks, field investigations, development engine test support and production engine assembly support.

Mechanical Systems, Externals, & Nacelles (MSEN): The MSEN Engineering organization is responsible for the design, development, and in-service support of power transmission systems; bearing compartments and rotor support design and analysis; oil and thermal management systems; engine externals packaging and architecture; and nacelles for both commercial and military engine models. Key technical disciplines include Project Engineering, Mechanical Design, Structural Analysis, Product Definition, and System Modeling.

External hardware encompasses a wide range of components such as tubes, brackets, electrical harnesses, and mounting structures strategically packaged on the outside of the engine. Externals Designers routinely interface with every module of a Pratt & Whitney gas turbine engine and integrate multiple systems, including lubrication, electrical, fuel, and air systems. They also support operational engines by working with customer support teams to troubleshoot issues and return engines to service. During engine overhauls, Externals Design collaborates with overhaul shops to investigate findings and establish part limits for continued service.

As an Externals Design Engineer Intern at Pratt & Whitney, you will……

→Execute design tasks, support field investigations, support development engine testing and support production engine assembly.
→Create and modify externals designs to meet project requirements.
→Collaborate with cross-functional teams to deliver engineering solutions.
→Support build and teardown activities, ensuring designs are implemented correctly.
→Utilize engineering drawings and follow written and verbal instructions.
→Apply knowledge of CAD and PDM tools, such as Siemens NX and Teamcenter, to develop models and drawings.
→Work closely with engineering teams to ensure project success

→Develop technical knowledge in key design discipline areas, including blueprint interpretation, GD&T, externals component design, solid modeling, tolerance stack analysis, root cause assessments
→How to engage cross‑disciplinary teams to perform design tasks.
→How externals are designed and how their functions play a crucial role in engine operation
→How to communicate complex technical topics effectively to design and Integrated Product Team (IPT) members
→How to independently plan and execute the technical path for small design tasks
→Engineering Interns at Pratt & Whitney work on challenging, meaningful, and impactful projects across our business.
→Our intern program seeks to help you develop an understanding of the aerospace industry and learn about our company and its operations.
