Mechanical Engineer Opportunity At Marathon Petroleum

An exciting career awaits you at MPC, we're committed to being a great place to work – one that welcomes new ideas, encourages diverse perspectives, develops our people, and fosters a collaborative team environment. Responsibilities: As a Mechanical Engineer at a Marathon refinery, you can expect to become familiar with industry codes and best practices, build critical thinking skills, and gain an understanding of how all engineering disciplines work together as a cohesive team. You will also gain knowledge of various aspects of a refinery by working with a team of professionals who run a specific portion of the refining process. Most often, Mechanical Engineers will have an opportunity to work on more than one area of the refinery, leading to a broad understanding of how the plant operates. Finally, you will have the opportunity to expand your written and verbal presentation skills in a professional work environment.

The majority of Mechanical Engineering co-ops and interns enter into the following positions:

• Area Refining Engineer/Project Engineers develop and use project management skills to create project scopes, estimates, and schedules. Once a project is developed and approved, you, as the project manager, will oversee the design effort and assist in the construction process.
• Reliability Engineers support the refinery's Maintenance Department through design and development of equipment related improvements. Such improvements include root cause failure analysis, optimization of maintenance programs in rotating equipment (pumps, compressors, etc.), and troubleshooting fixed equipment (refinery pressure vessels, heat exchangers, piping systems, etc.). Reliability Engineers will also be continuously challenged to find new technology in design, materials and repair methods to achieve refinery goals of longer running times at lower costs.
