Mechanical Engineer - Centrifugal Compressor

Role scope

Installation and mechanical service

• Execute installation, pre-commissioning, mechanical inspections, overhauls, and commissioning of centrifugal compressors and auxiliary systems.
• Perform internal clearance measurements, shaft laser alignment, dial indicator alignment, and piping strain checks.
• Install, inspect, and troubleshoot dry gas and wet seals, journal and thrust bearings, labyrinth seals, and lube oil and seal gas skids.
• Lead compressor bundle removals and insertions, rotor swaps, and heavy-lift rigging operations.

Troubleshooting and reporting

• Diagnose mechanical faults, high vibration, bearing temperature anomalies, rotor dynamics issues, and lube oil or seal gas system malfunctions under outage deadlines.
• Support retrofits and upgrades to legacy mechanical components and integrate them with existing plant piping and infrastructure.
• Prepare daily progress reports, root cause analyses, punch lists, redlined mechanical drawings, and technical field service reports.
• Follow site-specific Lockout/Tagout protocols, Permit to Work requirements, and industry safety standards.

Required technical competence

• Hands-on operational and engineering knowledge of Baker Hughes (Nuovo Pignone) centrifugal compressors, including horizontally split and vertically split barrel configurations.
• Practical experience with precision measuring instruments such as micrometers, dial indicators, and bore gauges, and with laser alignment equipment such as Pruftechnik or Fixturlaser.
• Knowledge of compressor thermodynamics, aerodynamics, surge phenomena, dry gas seal operation, and API vibration limits.
• Knowledge of heavy-duty gas turbines, steam turbines, and high-speed multi-stage gearboxes.
• Ability to read and redline P&IDs, general arrangement drawings, mechanical cross-sections, and bills of materials.

Education and experience

• A bachelor's degree in Mechanical Engineering, Industrial Engineering, or a related technical discipline is required; significant direct field experience may substitute for formal education.
• At least 5 years of experience as a Field Service Engineer, Mechanical Advisor, or Millwright working specifically with heavy rotating equipment and centrifugal compressors is required.

Location and work setting

• The role is based in Qatar and requires on-site field service work at facilities.

Compensation

• Gross monthly salary is USD 3,500–4,500.
