• Two or more years of mechanical engineering experience in refining, petrochemical processing, chemical manufacturing, or a similar continuous-process industry.
• Working knowledge of refinery fixed and rotating equipment, mechanical design, failure analysis, corrosion and damage mechanisms, and maintenance practices.
• Familiarity with OSHA Process Safety Management requirements and applicable API, ASME, ANSI, ASTM, and National Board codes and standards.
• Ability to read and interpret engineering drawings, piping and instrumentation diagrams, isometrics, equipment data sheets, inspection reports, technical specifications, and vendor documentation.
• Proficiency with Microsoft Office applications and refinery engineering, inspection, maintenance, or project-management systems relevant to the role.
• Strong analytical, troubleshooting, organizational, written communication, and verbal communication skills.
• Ability to manage multiple priorities and work effectively with refinery employees, contractors, equipment vendors, and cross-functional teams in an operating environment.

Nice To Haves

• Engineer-in-Training certification or Professional Engineer licensure.
• Direct experience in an oil refinery or petrochemical facility.
• Experience with refinery mechanical integrity programs, API inspection standards, fitness-for-service evaluations, and recognized corrosion or damage mechanisms.
• Experience with reliability improvement, root-cause analysis, vibration analysis, condition monitoring, or risk-based inspection.
• Experience managing refinery mechanical projects from concept through commissioning, startup, and closeout.

Responsibilities

• Provide mechanical engineering support for refinery fixed and rotating equipment, including pressure vessels, piping systems, heat exchangers, fired heaters, storage tanks, pumps, compressors, turbines, valves, and associated systems.
• Evaluate equipment performance, degradation mechanisms, recurring failures, and operating concerns; lead or support root-cause analyses and develop corrective actions.
• Support the refinery mechanical integrity program by reviewing inspection findings, fitness-for-service assessments, remaining-life evaluations, repair plans, and equipment recommendations.
• Develop scopes of work, technical specifications, equipment data sheets, engineering calculations, cost estimates, schedules, and design packages for maintenance, turnaround, and capital projects.
• Review drawings, piping and instrumentation diagrams, calculations, vendor proposals, inspection reports, and design documents for technical accuracy and compliance.
• Provide field support for equipment troubleshooting, repairs, installation, commissioning, startup, shutdown, and performance testing in operating process units.
• Participate in management-of-change reviews, process hazard analyses, pre-startup safety reviews, incident investigations, risk assessments, and other process safety activities.
• Ensure engineering designs and recommendations comply with refinery procedures, OSHA Process Safety Management requirements, environmental and safety regulations, and relevant API, ASME, ANSI, ASTM, and National Board standards.
• Coordinate with Operations, Maintenance, Inspection, Reliability, Process Engineering, Procurement, contractors, and equipment vendors to execute work safely and efficiently.
• Provide engineering support during planned outages, unit shutdowns, turnarounds, equipment repairs, and unplanned operational events.
• Develop and maintain equipment strategies, preventive and predictive maintenance recommendations, engineering files, equipment records, and technical documentation.
• Monitor project costs, schedules, quality, contractor performance, and technical risks; communicate status and emerging issues to refinery leadership and project stakeholders.
• Identify opportunities to improve equipment reliability, energy efficiency, unit availability, refinery throughput, and lifecycle cost while maintaining process safety and environmental compliance.
• Provide technical guidance and mentoring to less-experienced engineers, inspectors, technicians, and maintenance personnel as assigned.

Benefits

• 401(k) match of up to 10%, with a one-year vesting timeline.
• Medical benefits starting on the first day of employment, with a 30% annual premium rebate.
• Free access to the Calm app for meditation, stress management, and sleep support.
• Potential additional annual incentives through the performance management program.
