Benefits: Health, Dental and Vision Insurance, 401K, PTO

Basic Responsibilities

• Lead mechanical and thermal integration for desalination and BOP systems (cooling, water, and power).
• 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.
• Contribute technical insights to client-facing proposals for industrial and data-center applications.

Required Qualifications

• Minimum bachelor's degree in mechanical engineering
• Licensed Professional Engineer (P.Eng. or PE) preferred.
• 10+ years of experience in mechanical systems integration, modular fabrication, and EPC management.
• Demonstrated ability to write and manage scopes of work, evaluate unit-rate vs. reimbursable contracts, and implement performance-based progress tracking.
• Strong understanding of risk allocation and incentives in EPC and modular project delivery.
• Experience with desalination, thermal power, or nuclear balance-of-plant systems preferred.
• Excellent communication and documentation skills.
