• Provide technical support to the inspection department, including specifying data needs for the safe and reliable operation of process plant and equipment.
• Assist in the implementation, management and optimisation of Risk Based Inspection (RBI) initiatives for the assigned areas of responsibility.
• Assist in formulating, implementing, maintaining and auditing Preventive Maintenance (PM) and Predictive Diagnostic Maintenance (PdM) programs.
• Develop, maintain and ensure continuous improvements of the refinery PM/PdM program.
• Assist Operations, Product Control, and Maintenance Departments in developing procedures, training, and processes to ensure equipment is operated within its design parameters.
• Advise engineering on new capital designs and installations to ensure that equipment reliability, operability, and maintainability are addressed.
• Develop and review equipment specifications and standards for reliability improvement.
• Develop and track cost justifications for reliability improvement.
• Provide quality control/assurance services for shop and field repairs.
• Lead and support Root Cause Failure Analyses and CauseMap investigations to ensure lessons learned from process plant and equipment failures.
• Ensure/follow up on the execution or implementation of reliability derived recommendations.
• Develop basic engineering packages for improvement projects, generating early phase Approval for Expenditure (AFE) documentation for justification and Management endorsement.
• Support safe and reliable operation of the process plant and equipment through Process Hazard Analyses (PHA) and ensure appropriate asset change management through Management of Change (MOC).
• Specify equipment according to standards and established practices prior to purchase, including the engineering review of repairs to process plant and equipment, both temporary and permanent.
• Utilise reliability database, SAP and other electronic tools to track cost, equipment histories and preventive/predictive maintenance.
• Manage the health and status of assigned asset areas and equipment within a multi-discipline team including Operations and Engineering representatives.
• Lead in preparation and planning of the routine reliability reviews with Management, identifying and recommendations for addressing Bad Actors where appropriate.
• Be responsible for the development of maintenance or repair scope for the assigned areas of responsibility for online and offline maintenance events.
• Must be able to complete defined periods of on-call, as well as provide out of hours support to Refining operations, with short notice, participating in troubleshooting on an as needed basis.
• Must be able to travel to Valero Headquarters in San Antonio, Texas on an infrequent basis for training and networking.
• Perform other duties as assigned.

Required:
Bachelor’s or higher level degree in Engineering.

Preferred:
Chartered Engineer status with the Institute of Mechanical Engineers (IMechE) is preferred.
5 years of experience in reliability or maintenance engineering preferred.
Experience in computer‑aided engineering (CAE) simulation software such as Caesar II and/or Plant Manager.
Experience in the use of Plant Condition Management Software (PCMS) to locate, understand, and manage equipment inspection data, history and schedules.
Ability to complete API 579-1/ASME FFS-1 Level 1 and Level 2 Fitness-For-Service (FFS) assessments to demonstrate safe operation of plant and process equipment.
Knowledge of pressure vessel and piping component design including material, temperature, fabrication, examination and testing considerations, including ASME Section VIII Div1 & Div2 for process vessels and ASME B31.3 for process piping systems, or equivalent.
Knowledge of metallurgy, alloy selection, basic welding concepts, plus an overview of corrosion and materials damage mechanisms in the major refining process units.
Knowledge of Risk-Based Inspection (RBI) practices including industry standard API RP 580.
Knowledge of welding processes and how to select the optimal method for specific applications, aligned to ASME, API as well as NBIC repair standards.

This is a full-time site-based role.
