Pratt & Whitney is a world leader in the design, manufacture and service of aircraft engines and auxiliary power systems and has been revolutionizing modern flight for over 100 years. Join us and help shape the future of aerospace and defense.

Pratt & Whitney is seeking a Thermo-Fluids Engineer to join its Mechanical Systems, Externals, and Nacelles (MSEN) engineering team. In this role, you will support the design and analysis of gas turbine mechanical systems for aircraft applications, focusing on bearing compartments, gearboxes, and oil/air service tubes. You will perform thermal and fluid-flow analyses, develop physics-based methods and tools, and collaborate with multidisciplinary teams to deliver robust engineering solutions.

What You Will Do:

Perform thermo-fluid design analysis for gas turbine bearing compartments, gearboxes, and oil/air service tubes used in aircraft applications.
Develop and apply physics-based methods, numerical models, and tools to evaluate designs and improve heat transfer and fluid-flow analysis capabilities, including conduction, convection, and radiation.
Use programming tools such as Python and MATLAB, along with data analytics and machine learning methods, to support engineering analysis, investigate real-world data, and develop analytical tools.
Collaborate with design, structures, lubrication systems, and project engineers to develop integrated solutions for gas turbine mechanical systems.
Communicate technical progress, analysis results, challenges, and proposed solutions effectively to peers and leadership teams.

Travel Requirement: less than 10% (Domestic and International).

What You Will Learn:

Gain deeper knowledge of gas turbine mechanical systems, including bearing compartments, gearboxes, and oil/air service systems.
Develop expertise in thermodynamics, heat transfer, fluid mechanics, and thermal management for aircraft engine applications.
Build experience developing physics-based analysis methods, numerical models, and engineering tools.
Strengthen technical capabilities using industry-standard simulation, CAD, and programming software.
Gain exposure to data analytics, machine learning, and cross-functional engineering collaboration.

Qualifications You Must Have:

Bachelor of Science degree in Mechanical Engineering or Aerospace Engineering with 2 years of relevant experience, or an Advanced degree in a related field. Relevant experience in aviation, industrial gas turbines, turbomachinery, or automotive engine industries with engineering knowledge applicable to thermodynamics, heat transfer, and fluid-flow analysis.

Qualifications We Prefer:

Advanced degree in Mechanical Engineering or Aerospace Engineering, with coursework in thermodynamics, heat transfer, and fluid flow.
Knowledge of analysis software such as ANSYS Mechanical, Siemens Simcenter, Fluent, STAR-CCM, or DYMOLA for thermal and fluid-flow applications.
Experience with CAD tools such as UG, NX, Design Modeler, Workbench, or SpaceClaim.
Prior aircraft engine design and analysis experience, including familiarity with lubrication systems.
Proficiency with Microsoft Office (PowerPoint, Excel, Word, and OneNote), numerical modeling tools, and programming languages such as Python or MATLAB.

What We Offer:

Eligible for Relocation.
