Internship - Fall 2026 - Sustainable Propulsion Performance Analysis and Methods Development

RTX • Mississauga, ON

10d • Onsite

About The Position

Pratt & Whitney Canada (P&WC) is a global leader in aerospace innovation, proudly headquartered in Longueuil, Quebec, since 1928. They design and manufacture next-generation aircraft engines that power the world’s largest fleet of business, general aviation, and regional aircraft and helicopters. For nearly 100 years, their teams have been at the forefront of propulsion technology, pushing boundaries to make flight more efficient and reliable. Their engines support missions that truly matter, from transporting people and essential goods, to enabling emergency medical services, humanitarian operations, and wildfire suppression around the world. P&WC was named one of Canada’s Best Employers for 2026 by Forbes for the 11th consecutive year and ranked #1 employer in the aerospace and defense industry in the country. The student will be part of the advanced performance engineering team and will have access to the experience, tools, and data available within this organization. The focus will be on research, modeling, and analysis of engine performance and non-CO2 climate impacts, particularly how these are quantified in engine performance.
