• Procurement & vendor management: Prepare mechanical equipment specifications and requisition packages, support technical bid evaluations, and assist with vendor selection.

• Design & code compliance: Review drawings and ensure mechanical systems meet applicable codes and regulations, including ASME, API, and local safety requirements.

• Cross-functional collaboration: Work with multidisciplinary EPC partners and internal teams (process, structural, piping, electrical, instrumentation, and construction management) to deliver integrated, buildable engineering packages.

• Technical documentation: Develop and maintain engineering drawings, specifications, and project documentation.

• Budget & timeline management: Track project costs and schedules to help ensure alignment with capital plans.

• Commissioning & safety reviews: Support checkouts, startup planning, and Pre-Startup Safety Reviews (PSSRs) to transition new installations safely into active plant operations.

Key Qualifications and Skills

• Technical knowledge: Deep technical knowledge and broad practical experience to ensure mechanical designs, specifications, vendor deliverables, fabrication approaches, and field execution plans are technically sound.

• Software proficiency: Strong experience with 2D and 3D modeling tools such as AutoCAD or SolidWorks.

• Education: Bachelor’s degree in mechanical, industrial, manufacturing, construction engineering, or a related field.

• Attention to detail: Demonstrated experience across the full capital project lifecycle—from concept and detailed design through procurement, fabrication, construction, commissioning, and Management of Change.
