Mechanical Design Engineer

JOB DESCRIPTION SUMMARY

The Mechanical Design Engineer will be responsible for designing, developing, reviewing, and improving mechanical systems, desalination units, piping layouts, skid-mounted RO systems, and related engineering solutions that support SAWACO’s operational and strategic growth objectives.

The role ensures that designs are technically sound, cost-effective, compliant with applicable engineering standards, and suitable for manufacturing, installation, operation, and maintenance. The position also supports business initiatives such as Mobile Water Rental Units, Ultra-Pure Water Systems, Water-as-a-Service (O&M), and plant expansion projects.

DUTIES AND RESPONSIBILITIES

• Prepare mechanical designs for RO plants, skid-mounted desalination units, piping systems, pumping stations, and supporting equipment.
• Develop General Arrangement (GA), fabrication, assembly, and installation drawings.
• Perform equipment sizing and selection for pumps, pressure vessels, piping, valves, and other mechanical components.
• Review engineering specifications, customer requirements, and project documentation.
• Coordinate mechanical designs with electrical, instrumentation, civil, and process engineering disciplines.
• Support proposal preparation by providing technical layouts, equipment lists, and engineering calculations.
• Prepare Bills of Materials (BOMs), material specifications, and technical procurement documentation.
• Support Procurement during the technical evaluation of suppliers and equipment.
• Review vendor drawings and approve technical submittals.
• Participate in design reviews, constructability reviews, and project meetings.
• Support commissioning, troubleshooting, and technical problem-solving during project execution.
• Maintain engineering documentation, drawing revisions, and design records in accordance with document control procedures.
• Recommend engineering improvements to enhance efficiency, reliability, maintainability, and cost optimization.

Skills

QUALIFICATIONS AND EXPERIENCE
