About the role

Air Liquide Maritime, part of Air Liquide's InnoTech business, is looking for a Senior Turbo Expander Skid Design Engineer for its Global Engineering & Construction division. As technical lead, you will design, integrate and package turbo expander rotating machinery and their auxiliary skids (lube oil systems, seal gas panels and process piping), supporting Cryogenic Air Separation Units, Hydrogen Liquefaction plants and Carbon Capture initiatives.

Key responsibilities

• Develop complete skid layouts and structural analysis, including lifting lug calculations, and generate assembly drawings, P&FDs, fabrication drawings, BOMs and technical specifications.
• Integrate instrumentation, valves and electrical junction boxes in line with hazardous area classifications.
• Lead standardised mechanical layouts and modular designs for turboexpander skids to cut lead times and costs.
• Draft technical specifications, validate mechanical, fluid and thermal calculations (hydraulics, pressure drop, heat exchanger sizing, PSV sizing, lifting criteria) and evaluate vendor proposals.
• Take part in FAT and mechanical running tests at vendor facilities.
• Work with process, instrumentation and electrical engineers, and lead HAZOP and 3D model reviews.
• Share lessons learned and stay current with industry standards and mechanical design advances.

Required profile

• Bachelor's degree in Mechanical Engineering.
• Minimum 10+ years designing, packaging and integrating high-speed rotating equipment (turbo expanders, centrifugal compressors or steam turbines) in oil & gas, petrochemical or industrial gas.
• Proven track record delivering modular skid packages from concept to fabrication.
• Preferred: turbo expander design experience, structural design knowledge, Chinese language, and experience with risk mitigation, quality compliance and process governance.

Required skills

• API 617, API 614, ASME B31.3 and ASME Section VIII.
• SolidWorks and ANSYS; Aveva E3D/PDMS mentioned as examples.
• Cryogenic materials selection and thermal insulation (below -150°C).
