We don't just talk about progress and innovation here - we make it happen, with our customers, where we work and live. Together, we are building a better world, so we can all enjoy living in it.

About the Role

Caterpillar's Corporate Engineering Intern program seeks students currently enrolled in a four-year university to work alongside engineering professionals to learn and apply themselves to project work within their teams.

Interns will have assignments that provide them with experience and significant learning opportunities. In addition to this work, Interns can network with management throughout the company to learn about Caterpillar areas outside their assigned team. Students can deepen their business skills in their assignments through team and business partner interactions, develop their skills, conduct presentations, and measure their success through the performance and evaluation process.

You'll join a team with diverse project responsibilities and have valuable networking opportunities with all levels of Caterpillar employees. The internship is a 40-hour-per-week assignment lasting 12 weeks.

You can focus on building technical abilities in roles including (but not limited to):

• Product Design: Engineer components & systems for Caterpillar products to meet our customers' needs. Deliver solutions by leading collaboration with cross functional teams throughout our value chain starting from the initial concept through production.
• Simulation/Performance Analysis: Engage with analysis methods such as CFD - Computational Fluid Dynamics (ANSYS), FEA - Finite Element Analysis, 3D modelling, root cause investigation; system/subsystem/component design optimization, structural dynamics, development and optimization of Engine, Aftertreatment, Battery, Fuel Cell, Powertrain, and/or Machine System performance.
• Test/Validation/Hands on: Apply strong mechanical engineering understanding in a test/validation (hands-on) environment, troubleshooting issues, and collaborating with others for optimal results.
• Controls Development: Develop/Implement control system algorithms using MATLAB/Simulink for various control systems including but not limited to engine controllers, machine implement controllers as well as powertrain controllers. Will be responsible for understanding the feature requirement, implementing it as well as testing it prior to a production roll out.
• Electronic Components: Design and test various electronic control modules as well as various electronic components. Work with various internal Caterpillar clients to understand controller/component requirements, work with suppliers on design and validation of the components, as well as testing the components in various environments. Other duties may include design of Printed Circuit Board schematics as well as perform digital/analog/power circuit analysis & testing and ensuring that FMEAs [Failure Mode and Effects Analysis] are conducted and documented to meet stringent Caterpillar quality requirements.
