Performance/Simulation/Application Engineer

About the Role

As a Performance/Simulation/Application Engineer with the Large Power Systems Division (LPSD), you will serve as an experienced contributor on complex projects that support and enhance Caterpillar product performance, durability, reliability, and quality. LPSD designs and manufactures large diesel and natural gas engines, powertrains, and key engine systems for power generation, industrial, marine, oil & gas, rail, services, and Cat® machine applications worldwide. You will partner with global teams, provide technical guidance, and stay abreast of innovative technology while growing your professional network.

This position is onsite 5 days a week in either Mossville, IL (Building AC) or Lafayette, IN (Lafayette Engine Center, Building A). Domestic relocation is available, but sponsorship is not. Travel requirements are up to 10%.

Responsibilities

• Perform finite-element (FEA) projects for engine core components, including cylinder heads, blocks, liners, and pistons.
• Execute coupled coolant CFD-heat transfer analysis, structural analysis, and thermo-mechanical fatigue (TMF) simulations to assess component performance and durability.
• Collaborate with cross-functional teams to define simulation requirements for new product development, current product issue resolution, and cost reduction projects.
• Prepare clear documentation of analysis objectives, assumptions, methods, results, and conclusions.
• Interpret simulation results and provide actionable recommendations for design improvements.
• Collaborate with engine test teams to improve simulation tool capabilities.
• Stay current with emerging technologies and contribute to the development of new simulation methods and tools.

Requirements

• Master’s degree in mechanical engineering, aeronautical engineering, or a related engineering discipline.
• Strong proficiency in structural FEA, including nonlinear material behavior, contact modeling, and non-metallic seal materials (e.g., rubbers and gaskets).
• Experience performing thermal and thermo-mechanical coupled (TMF) simulations for durability assessment.
• Ability to conduct fatigue life prediction (HCF, LCF, TMF) using industry-standard or Caterpillar fatigue analysis methods and tools.
• Proficiency with major CAE solvers such as Abaqus or ANSYS Mechanical.
• Strong capability with pre/post-processing workflows using tools like Abaqus, Simlab, or HyperMesh.
• Strong analytical and problem-solving skills, with the ability to handle increasingly complex assignments.
• Excellent communication skills for conveying technical information to team members and other teams.
• Demonstrated project leadership capabilities.

Skills

• Understanding of internal combustion engine loading, kinematics, and durability drivers.
• Knowledge of high-temperature material behavior, cyclic thermal gradients, and engine thermal-stress mechanisms.
• Knowledge and experience in manufacturing processes, such as casting, forging, welding, and heat treatment.
• Experience with scripting and automation (Python, C/C++, FORTRAN) to streamline pre/post-processing and batch simulation workflows.
• Experience with fatigue/durability tools such as fe-safe.
• Accuracy and attention to detail in completing tasks with high precision.
• Effective communication, including delivering feedback, listening without defensiveness, and avoiding technical jargon when inappropriate.
• Problem-solving experience, including organizing resolution efforts and analyzing alternative strategies.
• Technical excellence in developing solutions to significant technical challenges.
• Basic project management skills, including planning, organizing, and monitoring projects.
