  • Pumps, Compressors, and Turbines

• Apply knowledge of manufacturing and fabrication methods, including machining, grinding, welding, assembly, and inspection, together with materials engineering, metallurgy, and material selection.

• Provide independent technical review of project PPFDs, PFDs, and P&IDs for constructability, operability, and multidisciplinary coordination.

• Develop and maintain standardized engineering procedures, calculation methods, and design practices that support consistent technical quality.

• Ensure project compliance with applicable codes and standards, including:

  • Title 49 CFR Parts 190-199, 40 CFR 112, 40 CFR 264
  • ASME BPVC-VIII Pressure Vessel
  • API 620, API 650, API 12C Tank Design
  • Piping Design Systems, ASME B31.3, B31.4, B31.8
  • API 610 Pumps, Centrifugal Pumps (1 hp to 10,000 hp)
  • API 674/675/676, Positive Displacement Pumps
  • API 682, Shaft Sealing Systems for Centrifugal and Rotary Pumps
  • Mechanical Seal Design Systems
  • API 520/521 Pressure Relief Devices

Project Engineering & Deliverable Management

• Serve as Project Engineer for assigned projects, with responsibility for scope, schedule, budget, and coordinated technical execution across engineering disciplines.

• Coordinate multidisciplinary deliverables and serve as the primary day-to-day technical point of contact for the client.

• Develop and maintain core project documentation, including design basis documents, scopes of work, deliverable lists, and progress reports.

• Support procurement through RFQs, technical bid evaluations, and purchase recommendations for mechanical and rotating equipment; review vendor quotations, data sheets, and drawings for compatibility with the intended design.

• Perform QA/QC reviews of drawings and cross-discipline deliverables to verify safe, code-compliant designs that align with project objectives.

• Incorporate company standards, client and municipal requirements, and applicable regulatory codes into project deliverables.

• Respond to RFIs, technical queries, design changes, and construction issues throughout the project lifecycle with clear, timely technical guidance.

• Conduct field assessments and walkdowns, and review site-specific geotechnical, survey, and civil information to support design development.

• Provide engineering support during construction, commissioning, and startup, including punch list resolution and as-built documentation.
