• Experience with P&ID/PFD development, equipment sizing, and capital project execution.
• Demonstrated ability to lead multidisciplinary reviews and mentor junior engineers.
• Strong communication skills and ability to convey technical content to cross-functional teams.
• Willingness to support field activities, turnarounds, and confined space entries.

Responsibilities

• Support the Project Team with project engineering requirements, process design input, technical reviews, scope definition, and alignment with engineering standards and best practices.
• Identify and evaluate capital and optimization projects aligned with safety, environmental, and economic goals and standards.
• Collaborate with business team, technical, and project teams resources to advance initiatives.
• Perform equipment sizing and specification (pumps, heat exchangers, columns, reactors, piping, etc.).
• Evaluate existing processes for performance improvements, yield enhancement, energy efficiency, and cost reduction.
• Research and assess technologies to improve unit operations and develop site-specific implementation plans.
• Support Front-End Engineering Design (FEED) and detailed engineering phases.
• Develop and optimize process flow diagrams (PFDs), piping and instrumentation diagrams (P&IDs), and heat and material balances.
• Lead multidisciplinary reviews of project designs addressing process design, safety, environmental compliance, reliability, operability, constructability, and cost estimation.
• Ensure project development complies with PBF's capital project best practices, industry design standards, and site-specific requirements.
• Participate in PHAs, HAZOPs, and safety reviews.
• Perform Safety Relief Reviews (SRRs) and maintain the PSPPM database.
• Ensure process designs comply with regulatory and environmental standards.
• Interface with construction and project execution teams during construction, commissioning, and startup of new and refurbished facilities.
• Provide field verification and troubleshooting support to ensure accurate implementation of process designs.
• Support the area process engineers during unit turnarounds, including confined space entry and inspections as needed.
• Collaborate with operations, maintenance, reliability, safety, and environmental teams to ensure effective and compliant process designs.
• Mentor process engineers in areas of expertise.
• Collaborate with the revision and update of PBF's engineering practices and document lessons learned.
• Active participation in the site's Loss Prevention System (LPS) and use of its tools.
• Support and participate in best practice networks as needed.
• Collaborates with the Process Engineering Leads as needed to support technical tasks requiring an experienced process engineer or expertise beyond the scope of the area Process Engineers.
• Utilize digital tools (e.g., PI System, Seeq) for process monitoring, troubleshooting, and optimization.
• Support and contribute to process modeling efforts, collaborating with the process engineering team to optimize and troubleshoot refinery operations.
• Prepare technical reports, documentation, and presentations to communicate project progress and recommendations.
• Utilize Aspen HYSYS (and other applicable simulation tools) to develop, tune, and maintain rigorous process models that enable unit optimization, troubleshooting, constraint identification, debottlenecking, evaluation of operational changes and capital projects, including support for design basis development and engineering studies.
