About The Position

Pratt & Whitney Canada (P&WC) is a global leader in aerospace innovation, proudly headquartered in Longueuil, Quebec, since 1928. We 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, our teams have been at the forefront of propulsion technology, pushing boundaries to make flight more efficient and reliable. Our 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. Pratt & Whitney Canada was named one of Canada’s Best Employers for 2026 by Forbes, marking the 11th consecutive year the company has earned this recognition. Pratt & Whitney Canada also ranked #1 employer in the aerospace and defense industry in the country. In addition, our headquarters continue to be recognized among the top employers in the Montreal region. Together, these distinctions reinforce our reputation as an employer of choice in Montreal, across Canada, and around the world. Structural Systems engineers are responsible for load, deflection and stress analysis and experimental testing of gas turbine engines and sub-systems from the early concept phase through certification and field service. We have three main sub-discipline's in Structures Systems: 1) Structural Integration - support concept development of engine architecture, generate full engine system models for load, deflection and stress analysis, generate, document and manage static and dynamic loads, integrate the engine structure with the airframe. 2) Engine Impact Dynamics - utilize LS/Dyna to generate full engine models to predict engine system response to highly dynamic short duration impact events such as turbofan blade off, bird ingestion, hail impact and turboprop/shaft engine system response to stage blade off, shaft shear and overspeed. 3) ECN Stress Analysis - analyze, develop and test hardware designed within the ECN module including engine mounts, composite aerostructures, tubes, support hardware, fairings, accessories, bleed systems and nacelle interfaces.

Requirements

Be eligible to work in Canada.
Be enrolled in a Canadian university throughout your internship.
Be able to work on-site in the province where you are hired if applicable.
Have completed at least 2 academic years (4 semesters) towards a university degree in mechanical or aerospace engineering.
Knowledge of load, stress, and fatigue life analysis for metallic and composite structures.
Appreciation of gas turbine static and rotating structures.
Strong practical mechanical aptitude
