Post-Contract Process Engineer
Posted Updated
Key Responsibilities
- Translate preliminary pre-contract designs, Process Flow Diagrams (PFDs), and Piping & Instrumentation Diagrams (P&IDs) into finalized, execution-ready process engineering packages.
- Perform detailed hydraulics, pump sizing, mass balances, chemical consumption calculations, and equipment line sizing across UPW, reclaim, and wastewater process units.
- Review and approve vendor technical submittals, equipment data sheets, instrument specifications, and component selections (e.g., pumps, resin vessels, RO/EDI skids, UV systems, ozone destructors).
- Coordinate closely with Mechanical, Piping, Electrical, and Automation teams to resolve technical interfaces and develop process control philosophy.
- Assist in pre-commissioning, chemical cleaning/sanitization, flushing, and media/resin loading sequences.
- Troubleshoot operational bottlenecks, process instabilities, and analytical anomalies during startup phases.
- Serve as the primary technical point of contact for client representatives, owners' engineers, and managing contractors during the execution phase.
- Prepare comprehensive operations and maintenance (O&M) manuals, process testing protocols, commissioning procedures, and final validation documentation for handover.
