Job Description

Caterpillar is the world’s largest manufacturer of construction & mining equipment, diesel engines, and industrial gas turbines. With over 10,000 engineers worldwide, Caterpillar has been developing class-leading machines and engines for decades. We have an exciting opportunity for a Combustion Simulation Engineer/ Low C Fuels. The Energy & Transportation Technology (E&TT) team is part of Caterpillar’s Integrated Components & Solutions Division (ICS), which has global responsibility for advancing technologies to support future product needs. Many exciting hardware and software technologies are being identified, researched, and developed for future powertrains for off-road machines, including approaches for increased power density, high-efficiency hybrid powertrains, alternative (low-Carbon-intensity) fuels, waste heat recovery, energy management, electronics and controls, advanced power sources, dual-fuel engines, and ultra-low exhaust emission technologies. For the highly-transient, high power requirements of heavy-duty off-road applications, a spectrum of low-to-zero Carbon solutions will be needed for the future. These applications provide a significant de-carbonization challenge, and talented, innovative engineers are required to deliver customer-focused solutions.

Job Duties:

  • The successful candidate will have the technical skills, initiative, and communication skills necessary to execute and deliver on simulation technology development projects in the energy and power systems space.
