Linear Programming Engineer

Aramco energizes the world economy.

Aramco occupies a unique position in the global energy industry. We are the world's largest producer of hydrocarbons (oil and gas), with the lowest upstream carbon intensity of any major producer.

With our significant investment in technology and infrastructure, we strive to maximize the value of the energy we produce for the world along with a commitment to enhance Aramco’s value to society.

Headquartered in the Kingdom of Saudi Arabia, and with offices around the world, we combine market discipline with a spanning view of the future, born of our nine decades experience as responsible stewards of the Kingdom’s vast hydrocarbon resources. This responsibility has driven us to deliver significant societal and economic benefits to not just the Kingdom, but also to a vast number of communities, economies, and countries that rely on the vital and reliable energy that we supply.

We are one of the most profitable companies in the world, as well as amongst the top five global companies by market capitalization.

Overview

We are seeking a Linear Programming Engineer to join the Central Planning & Modeling Division.

The division is responsible for optimizing crude allocation and the operations of global manufacturing facilities in order to maximize revenue, increase profitability, and capture international market opportunities. The division also acts as the LP gatekeeper for wholly owned refineries and the global MPIMS model, and maintains an integrated global planning model which is used for optimizing global crude allocation and exploration of new international markets and integration options.

Your primary role is to consult on complex engineering and LP problems, review existing and new rigorous simulations in order to update or build up shift vectors for sub-models in PIMS structure, and maintain rigorous simulation accuracy to conduct LP backcasting, recommending improvements as required. This role will also have the opportunity to build a new grassroots refinery rigorous simulation, mentor and train less-senior LP engineers and process engineers, and provide specialized technical service in recognized engineering fields.

Key Responsibilities

The successful candidate will be required to perform the following:

1. Run the rigorous simulation in order to identify deviation from simulation and actual conditions.
2. Run the wide refinery model after short-range operating model (SROP) optimization to identify operational opportunities in the refinery.
3. Define data and work processes required to maintain and update rigorous simulations.
4. Develop non-linear equations to reflect operational variables into the Process Industry Modeling System (PIMS) Advanced Optimization (AO) model.
5. Keep the hybrid model for LP Engineers accurate.
6. Work with process engineers to guarantee accurate simulation output and debottleneck constraints to maximize refinery benefits.
7. Perform “back-casting” and issue a monthly report on the rigorous simulation gap along with required mitigations.
8. Support stakeholders in creating new models to evaluate new projects for downstream business.
9. Support ASSAY experts to calibrate the True Boiling Point (TBP) and cut points to reflect the actual column efficiency.

Minimum Requirements

The successful candidate must hold a Bachelor’s degree in Chemical Engineering or a related field; a Master of Business Administration (MBA) or a relevant advanced degree is strongly preferred.

1. Minimum of 9 years of professional experience in consulting and/or refinery industries, with an in-depth understanding of rigorous simulation for refinery processing units.
2. Expertise in developing rigorous simulations to extract shift vectors and process objectives, with at least 7 years of experience in Aspen Technology’s HYSYS model or PETROSIM.
3. Experience in developing rigorous simulations for hydrocracking, FCC, DHT, catalytic, and coker reforming units, and building a rigorous simulation model of a complete refinery (Wide Refinery Model).
4. A thorough knowledge of engineering practices, economic principles, and calculation methods.
5. Expertise in international business and cross-cultural professional practices.
6. Experience in developing integration between rigorous simulation models and ASPEN PIMS.

Working Environment

Our high-performing employees are drawn by the challenging and rewarding professional, technical, and industrial opportunities we offer, and are remunerated accordingly.

At Aramco, our people work on truly world-scale projects, supported by investment in capital and technology that is second to none. As a global energy company, we are faced with addressing some of the world’s biggest technical, logistical, and environmental challenges, and we invest heavily in talent development.

We have a proud history of educating and training our workforce over many decades. Employees at all levels are encouraged to improve their sector-specific knowledge and competencies through our workforce development programs – one of the largest in the world.
