The Transmission Mechanical Engineer will be responsible for the design of transmissions and gear boxes for military ground vehicles including tanks, howitzers, and infantry fighting vehicles. Projects will range in scope from advanced research, development, and testing of future transmissions to failure analysis and incremental improvements of existing products.

Location: Muskegon, Michigan, United States

Essential Functions:

● Responsible for transmission and transmission sub system design, including analysis, integration, and
performance in the combat vehicle application.
● Develop innovative technical concepts and perform mechanical, hydraulic, and thermal analysis to ensure
new designs meet requirements.
● Develop & release detailed CAD models and drawings and release them for development qualification and
production activity using Engineering Change Proposals.
● Interface with cross functional teams, customers, and suppliers.
● Compose design verification test plans using a Systems Engineering approach that capture all performance
data to assess requirements compliance.
● Plan and oversee qualification activities including bench, dynamometer, and vehicle level testing.
● Lead failure analysis investigations on transmissions and gear boxes.
● Write and present internal & external engineering reports & presentations.


● Bachelor of Science (BS) in Mechanical Engineering from an accredited university required, with minimum 4
years relevant experience (2 years with MS or equivalent).
