Responsibilities
As an Electrical Engineer at a Marathon refinery, you will 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, Electrical 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 Electrical Engineering co‑ops and interns enter into the following positions:
Electrical & Instrumentation (E&I) Project Engineers
, Reliability Electrical & Instrumentation (E&I) Engineers
, and Process Control / Technical Service Engineers
.
Electrical & Instrumentation (E&I) Project Engineers work on a variety of real‑world electrical and instrumentation projects in a refinery setting. During your time at MPC, you will develop and utilize project management skills including scope alignment, cost and schedule development, and teamwork through multiple engineering phases. You will also support the area teams. We are committed to developing engineers into professional project managers who successfully manage projects of all sizes.
Reliability Electrical & Instrumentation (E&I) Engineers troubleshoot Electrical & Instrumentation issues at the refinery. As a reliability intern, you will help analyze failures of equipment, develop solutions for recurring equipment difficulties, submit Project Request Forms (PRF’s) to implement solutions, and understand equipment maintenance strategies. There will be opportunities to use electrical analysis software to solve coordination issues and run Arc Flash studies for the power system, as well as learn and understand about how our critical Refinery Safety Instrumented Systems (SIS) are applied.
Process Control / Technical Service Engineers can work on a wide array of projects in support of the process control systems installed throughout the refinery and product movements areas. The process control systems in the refinery provide real‑time control and data acquisition functions in support of operating the refinery process and electrical equipment. Typical college co‑op assignments include troubleshooting system power supply problems, control system programming, hardware and software lifecycle replacement projects, installing and troubleshooting communication networks, and monitoring control system performance metrics.
