MAINTENANCE MECHANICAL ENGINEER

About the Role
Support the safe, reliable, and efficient operation of an Oil & Gas storage terminal by providing technical engineering expertise, maintenance supervision, troubleshooting, equipment reliability improvement, and maintenance execution support. The Maintenance Mechanical Engineer is responsible for ensuring that assigned maintenance activities are properly engineered, planned, executed, inspected, and documented in accordance with applicable engineering standards, manufacturer recommendations, approved procedures, and HSSE requirements. This position plays a key role in improving asset performance, developing maintenance strategies, supervising technical execution, and strengthening the competence of Maintenance Technicians and Technical Assistants.

Key Responsibilities
Maintenance Engineering & Execution

• Provide technical engineering support for preventive, predictive, corrective, and breakdown maintenance of mechanical equipment and terminal infrastructure.
• Supervise and coordinate maintenance activities involving centrifugal pumps, mechanical seals, valves, piping, loading arms, firefighting systems, and other rotating and static mechanical equipment.
• Review maintenance work orders, technical scopes, work instructions, spare parts requirements, manpower, tools, and execution methodologies.
• Coordinate with Maintenance Planning and Operations to establish maintenance priorities, schedules, equipment availability, and resource requirements.
• Ensure maintenance activities are executed in accordance with approved engineering specifications, drawings, manufacturer recommendations, and quality requirements.
• Review maintenance findings, inspection results, equipment testing, and reinstatement requirements before recommending equipment return to service.

Equipment Reliability & Asset Integrity

• Investigate equipment failures, recurring defects, and abnormal operating conditions, identifying root causes and recommending corrective and preventive actions.
• Support development and optimization of preventive and condition-based maintenance strategies.
• Review equipment maintenance history, failures, performance trends, and work order data to identify reliability improvement opportunities.
• Support equipment criticality assessments, Failure Mode and Effects Analysis (FMEA), and Reliability-Centered Maintenance (RCM) initiatives.
• Coordinate equipment inspections, condition monitoring, and integrity assessments with relevant specialists.
• Identify and escalate asset integrity concerns, overdue inspections, and safety-critical equipment deficiencies.
• Support reliability improvement initiatives to reduce equipment failures, maintenance backlog, and unplanned downtime.

Engineering & Technical Documentation

• Develop, review, and improve mechanical maintenance procedures, work instructions, inspection checklists, and technical specifications.
• Review mechanical drawings, P&IDs, equipment manuals, and technical documentation required for maintenance execution.
• Prepare technical scopes of work, material specifications, and engineering justifications for maintenance-related modifications and repairs.
• Provide engineering support for equipment modifications, replacement, upgrades, and minor improvement projects.
• Ensure maintenance records, inspection findings, equipment histories, and technical documentation are accurate and traceable.
• Support Management of Change (MoC) processes, technical risk assessments, and engineering reviews within delegated authority.

HSSE, Process Safety & Quality

• Ensure assigned maintenance activities comply with terminal HSSE requirements, Permit to Work (PTW), isolation procedures, Life Saving Rules, and applicable engineering standards.
• Participate in Job Safety Analyses (JSA), risk assessments, incident investigations, and technical safety reviews.
• Verify that maintenance activities have appropriate technical controls, work instructions, inspection requirements, and acceptance criteria.
• Identify unsafe conditions, technical deviations, quality deficiencies, and potential equipment integrity risks.
• Exercise stop-work authority when activities are unsafe or required controls are not established.
• Support inspection, testing, and quality verification of contractor maintenance activities.
• Ensure corrective and preventive actions arising from maintenance failures, audits, inspections, and incidents are properly followed up.

Team Coordination & Competence Development

• Provide technical guidance and supervision to Maintenance Technicians, Junior Maintenance Technicians, and contractors.
• Support structured training, practical competency assessments, and development of junior maintenance personnel.
• Coordinate technical activities with Operations, Maintenance Planning, Procurement, Warehouse, HSSE, and Projects.
• Review work execution performance, identify technical capability gaps, and recommend training or improvement actions.
• Promote safe working practices, technical discipline, accountability, and continuous improvement within the Maintenance team.

Maintenance Performance & Resource Management

• Monitor maintenance performance indicators, including preventive maintenance compliance, corrective maintenance backlog, equipment reliability, and work order quality.
• Support maintenance budget preparation, cost estimates, material requirements, and resource optimization.
• Review spare parts requirements, technical specifications, material suitability, and stock criticality.
• Evaluate contractor technical performance, work quality, productivity, and compliance with approved scopes.
• Prepare maintenance engineering reports, technical recommendations, failure analyses, and improvement proposals for management review.
• Support shutdown planning, major equipment overhauls, commissioning, and maintenance readiness activities.

Qualifications and Experience

• Bachelor's degree in Mechanical Engineering or a related engineering discipline.
• Minimum 10 years of relevant experience in mechanical maintenance engineering within Oil & Gas, petrochemical, refinery, bulk liquid storage terminals, or similar process industries.
• Practical experience with centrifugal pumps, mechanical seals, valves, piping systems, rotating equipment, and mechanical maintenance activities.
• Good understanding of preventive, predictive, corrective, and condition-based maintenance strategies.
• Experience in equipment failure investigation, troubleshooting, root cause analysis (RCA), and reliability improvement.
• Knowledge of relevant engineering standards and industry practices, including applicable API, ASME, and ISO standards.
• Familiarity with Process Safety Management, PTW, isolation procedures, Management of Change, and industrial HSSE requirements.
• Ability to interpret P&IDs, mechanical drawings, technical specifications, and equipment documentation.
• Experience with maintenance management systems such as HxGN, SAP, INFOR EAM, or equivalent.
• Experience in technical contractor coordination, maintenance planning, and equipment inspection is advantageous.
• Good written and verbal communication skills in English.

Required Skills and Competencies

• Strong mechanical engineering fundamentals and practical troubleshooting capability.
• Ability to assess technical failures, evaluate maintenance findings, and recommend engineering solutions.
• Good understanding of equipment reliability, mechanical integrity, and maintenance quality requirements.
• Ability to prepare technical scopes, maintenance procedures, inspection requirements, and engineering reports.
• Strong planning, coordination, problem-solving, and decision-making skills.
• Ability to supervise technical execution and verify work quality within delegated responsibilities.
• Knowledge of risk assessment, process safety principles, and maintenance-related hazards.
• Effective communication and coordination with multidisciplinary teams, contractors, and Operations.
