Multi Body Dynamics Engineer Jobs (NOW HIRING)

The PACCAR Technical Center is seeking an experienced CAE – Structural & Dynamics Engineer to drive innovation in heavy-duty truck development. You will leverage advanced Finite Element Analysis (FEA) and vehicle dynamics simulation to deliver best-in-class durability, ride quality, handling, and NVH performance.

In this role, you'll partner directly with Kenworth and Peterbilt engineering teams to predict design viability, validate concepts through simulation-to-test correlation, and translate complex technical findings into actionable recommendations. You'll balance technical excellence with project leadership—managing timelines, and cross-functional resources while staying at the forefront of emerging vehicle technologies (electrification, autonomous systems, alternative fuels).

The ideal candidate combines 5+ years of CAE expertise with strong analytical skills, proven project management ability, and a commitment to continuous process improvement in a fast-paced, collaborative environment.

PACCAR is a Fortune 500 company established in 1905. PACCAR Inc is recognized as a global leader in the commercial vehicle, financial, and customer service fields with internationally recognized brands such as Kenworth, Peterbilt, and DAF trucks. PACCAR is a global technology leader in the design, manufacture and customer support of high-quality light-, medium- and heavy-duty trucks under the Kenworth, Peterbilt and DAF nameplates. PACCAR designs and manufactures advanced diesel engines and also provides customized financial services, information technology and truck parts related to its principal business.
