• Support design of modular, scalable desalination packages with standardized interfaces.
• Contribute to internal engineering standards and long-term design architecture.
• Optimize modularization to increase manufacturability and reduce field construction costs.
• Initiate pre-FEED and FEED design work; develop bid packages for EPC and engineering consultants.
• Manage engineering deliverables through clearly defined scopes of work, performance metrics, and earned-value progress tracking.
• Review and approve drawings, specifications, and construction packages; provide technical feedback to EPC partners.
• Drive accountability and alignment between owner and EPC through contract and risk management principles.
• Collaborate with project management, process, and controls teams to ensure integrated delivery of mechanical systems.
