Core Responsibilities

Primary Functions

Monitor and analyze the daily performance of assigned process units, including yields, product quality, catalyst performance, and energy consumption, to ensure operations meet production plans and quality specifications.
Develop and implement sophisticated process optimization strategies to enhance unit throughput, improve energy efficiency, and maximize the overall profitability of the refinery.
Act as the primary technical resource for troubleshooting complex operational upsets, conducting thorough root cause analysis (RCA), and providing effective, timely engineering solutions to prevent recurrence.
Lead or actively participate in critical Process Hazard Analyses (PHAs), such as HAZOP studies, Layer of Protection Analysis (LOPA), and What-If scenarios, to identify, evaluate, and mitigate process safety risks.
Manage a portfolio of small to medium-sized capital and expense projects from initial concept and justification through to detailed design, commissioning, and post-startup support.
Develop, review, and maintain essential process engineering documentation, including Process Flow Diagrams (PFDs), Piping & Instrumentation Diagrams (P&IDs), and safe operating limits.
Conduct detailed performance testing and health monitoring of critical process equipment such as distillation columns, reactors, heat exchangers, furnaces, and pumps to ensure reliability and efficiency.
Design and execute plant test runs to evaluate new catalysts, process chemicals, or innovative operating procedures aimed at driving continuous improvement and competitive advantage.
Provide essential engineering support during major plant turnarounds (shutdowns), including defining the work scope, planning inspections, and leading post-turnaround startup activities.
Build, validate, and maintain advanced process simulation models using tools like Aspen HYSYS or Pro/II to predict unit behavior, evaluate debottlenecking opportunities, and test optimization scenarios.
Serve as a key technical advisor to the Operations team, providing clear guidance on process control strategies, alarm management, and handling deviations from normal operation.
Ensure strict compliance with all local, state, and federal environmental regulations by monitoring emissions, managing waste streams, and preparing necessary regulatory and compliance reports.
Author, review, and champion Management of Change (MOC) requests, ensuring that any modifications to process, equipment, or procedures are rigorously evaluated for safety, environmental, and operational impact.
Develop and update comprehensive operating procedures and training materials for console operators and field personnel to ensure consistent, safe, and efficient plant operation.
Perform detailed heat and material balance calculations to accurately track unit performance, identify losses, and pinpoint opportunities for efficiency gains.
Collaborate closely with the maintenance and reliability departments to diagnose equipment issues, improve asset uptime, and develop long-term equipment strategies.
Participate in or lead incident investigations, leveraging your technical expertise to determine causal factors and recommend robust corrective and preventive actions.
Evaluate emerging technologies and process improvements from across the industry, developing economic justifications and proposals for their implementation at the facility.
Mentor and coach junior engineers, interns, and co-op students, providing them with technical guidance and supporting their professional growth and development within the organization.
Prepare and deliver clear, concise technical reports, project justifications, and performance updates in presentations to various levels of management.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis to answer complex operational questions.
Contribute to the organization's long-term technology and process improvement roadmap.
Collaborate with commercial and planning teams to translate market needs into tangible engineering requirements and operational targets.
Participate in agile project management frameworks for executing improvement projects and initiatives.
