PRINCIPAL MECHANICAL ENGINEER (PE REQUIRED)

About the Role

The Principal Mechanical Engineer is knowledgeable in multiple pipeline facilities and is qualified to handle large projects. Works independently with a wide latitude of technical authority and full work responsibilities, as well as limited administrative responsibilities within each project. This role is the primary producer of mechanical deliverables for the project scope but may also assign, guide, and review the work of lower-level engineers and designers. Work is periodically reviewed by the Chief Mechanical Engineer for accomplishment of objectives.

Open to both short and extended term assignments to the site, client’s office, or similar as may be requested by management.

Responsibilities

• Prepares, reviews, or approves mechanical engineering calculations.
• Prepares, reviews, or approves mechanical specifications and data sheets.
• Prepares, reviews, or approves material requisitions for equipment, materials, and subcontracts.
• Prepares, reviews, or approves technical bid evaluations for equipment and materials in cooperation with the Procurement Department.
• Prepares, reviews, or approves lists (equipment, valve, piping, tie-in, and specialty items).
• Coordinates, reviews, or approves PFDs, P&IDs, piping plans, and site layouts.
• Coordinates with client personnel relative to mechanical and piping activities.
• Reviews and approves vendor drawings and documents.
• Observes factory acceptance testing of equipment when required.
• Prepares or reviews mechanical engineering deliverable status reports and work plans.
• Reviews the mechanical scope of work to ensure it matches deliverable logs, project specifications, and/or contract documents when functioning as LME.
