What does a refinery process engineer do?

A Refinery Process Engineer is responsible for designing, optimizing, and troubleshooting processes within an oil refinery to ensure efficiency, safety, and regulatory compliance. They analyze data, monitor equipment performance, and recommend improvements to enhance productivity and reduce costs. Additionally, they work closely with operations, maintenance, and safety teams to implement process modifications and resolve technical issues. Their role is crucial in maximizing yield, minimizing energy consumption, and ensuring environmental compliance.

What are some of the typical day-to-day responsibilities for a refinery process engineer?

As a Refinery Process Engineer, your main responsibilities typically include monitoring and optimizing production processes, troubleshooting technical issues, and ensuring compliance with safety and environmental regulations. You may also be involved in analyzing process data, implementing improvements, and coordinating with operations, maintenance, and other engineering teams to maintain efficient plant performance. Your day could involve both desk work—such as process modeling and reporting—and fieldwork in the refinery, observing equipment and working closely with plant personnel. This blend of tasks helps ensure the refinery operates safely, efficiently, and at peak capacity.

What are the key skills and qualifications needed to thrive as a refinery process engineer, and why are they important?

To excel as a Refinery Process Engineer, a strong background in chemical engineering, process optimization, and safety protocols is essential, typically supported by a relevant engineering degree. Proficiency with process simulation software (such as Aspen HYSYS or CHEMCAD), knowledge of distributed control systems (DCS), and familiarity with industry certifications like Six Sigma or Professional Engineer (PE) licensure are highly valued. Problem-solving abilities, strong communication, and teamwork skills help professionals navigate dynamic refinery environments and coordinate with cross-functional teams. These competencies are crucial for ensuring efficient, safe, and compliant operations within complex refinery processes.

Job description

Department Summary
The Institute for Carbon Management (ICM) is a cross-campus technology-translation entity at the University of California, Los Angeles (UCLA). ICM translates pioneering carbon management strategies from the laboratory/bench-scale to pre-commercial/commercial-scale devices, prototypes, and software solutions. ICM's activities span two major focus areas: (1) Technologies for CO2 removal (from the atmosphere and the ocean), utilization, and avoidance (2) Technologies for creating new supply chains, and processing approaches for critical materials and elements (e.g., Li, Ni, Co, Mn, Mo) that are foundational to accelerating the clean energy transition, as well as reducing the carbon footprint of extractive processes. ICM is organized into action teams that are convergent, agile, and world-class. Prominently, these action teams have enabled ICM-born technologies to be awarded the NRG COSIA Carbon XPRIZE and the 2021 Liveability Challenge, among others. ICM's technologies are now being commercialized via spin-out companies, including CarbonBuilt Inc., Concrete-AI Inc., and Equatic Inc.
Position Summary
ICM is seeking an experienced Senior Process Engineer to join a multidisciplinary team of engineers and scientists developing carbon removal technologies with global impact. This role will lead projects from early-stage feasibility and pre-FEED through the design, construction, and delivery of demonstration-scale plants, requiring a strong blend of process engineering and project engineering expertise. Reporting to the Institute Director and Project Lead, this individual will drive day-to-day research and development activities, working closely with both internal teams and external stakeholders, including partners and vendors. The role requires hands-on technical leadership, effective cross-functional collaboration, and the ability to translate innovative concepts into scalable, real-world solutions. The successful candidate will collaborate with a diverse group of subject matter experts in a fast-paced, mission-driven environment focused on delivering measurable results.
Salary & Compensation
