Job description

An exciting career awaits you

At MPC, we’re committed to being a great place to work – a place that welcomes new ideas, encourages diverse perspectives, develops our people, and fosters a collaborative team environment.

Responsibilities

As a Chemical Engineer at a Marathon refinery, you can expect to become familiar with process equipment fundamentals 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, Chemical 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.

Specific Roles

Process / Technical Service Engineers

May work on a variety of projects in the Technical Services Department together with your mentor that put your classroom experience as a Chemical Engineer into practice. The versatility of this role provides exposure to the refining environment and technical aspects of the refinery. Typical tasks include developing and leading test runs to optimize refinery operations, performing process engineering calculations, monitoring and making recommendations on catalyst and adsorbent selection, and completing projects that provide improvements to refinery processes and equipment.

Operations Research Engineers

Assist in developing planning, blending, scheduling, and process models for refinery engineers. The models are used to optimize crude oil purchasing, refinery production, blending and finished product scheduling, and overall refinery production. Typical assignments include validating production data and mass‑balancing, process modeling, and building graphical interfaces for refinery process units.

Environmental Engineers

Work on projects that involve refinery compliance, applying engineering principles and calculations to environmental projects. Responsibilities include performing calculations for the Risk Management Plan, conducting physical surveys of refinery process units, working on wastewater treatment plant projects, and participating in inspections and testing conducted by federal, state or local authorities.

Products Control / Economics Engineers

Handle projects that cover operations, blending, and refinery economics. The role includes analyzing refinery process flow data, identifying equipment failures, updating gasoline blend and tank sample information, and developing applications to better present process data for operating decisions.
