Job description

Project Engineer

Job Summary

We are seeking an experienced Mechanical Engineer with a strong background in construction oversight and the design of water and wastewater treatment systems. You will lead the step-by-step mechanical design, planning, and site construction execution for pumping stations, water treatment plants (WTP), and sewage treatment plants (STP)

Key Responsibilities

1. Step-by-Step Design Phase

• Phase 1: Requirements & Analysis – Review project specifications, flow capacities, and regulatory standards to calculate fluid dynamics, pressure drops, and equipment sizing.

• Phase 2: Conceptual & Schematic Design – Develop initial mechanical concepts, process flow diagrams (PFDs), and piping and instrumentation diagrams (P&IDs) for water and waste networks.

• Phase 3: Detailed Engineering & CAD Modeling – Create comprehensive 2D/3D layouts using tools like AutoCAD Plant 3D or similar modeling software for piping, ductwork, and equipment placement.

• Phase 4: Equipment Selection – Select efficient pumps, valves, blowers, screens, and chemical dosing systems tailored to municipal or industrial waste demands.

• Phase 5: Technical Documentation – Prepare bills of materials (BOM), technical datasheets, and design calculation reports for procurement and regulatory compliance.

2. Construction & Site Supervision Phase

• Oversee mechanical installation activities on-site to ensure strict alignment with approved design drawings and contract documents.

• Coordinate with civil, electrical, and plumbing teams to resolve clashes and streamline on-site workflow.

• Review contractor submittals, inspect mechanical equipment delivery, and manage Requests for Information (RFIs).

• Conduct site safety checks and enforce compliance with local and international engineering codes (e.g., ASTM, NFPA).

3. Testing, Commissioning & Handover

• Plan and execute hydrostatic testing, flushing, and mechanical run-tests for pumps and piping networks.

• Troubleshoot system anomalies during plant commissioning and hand over fully operational assets to facility management teams.

Qualifications & Requirements

• Education: Bachelor’s Degree in Mechanical Engineering (Professional Engineer / Registered Mechanical Engineer license preferred).

• Experience: Minimum of 5 to 8 years of total engineering experience, with at least 4 years focused specifically on the design and construction of water supply, wastewater, or stormwater infrastructure.

• Technical Skills:

  • Advanced proficiency in AutoCAD Plant 3D or specialized piping design software.

  • Deep understanding of fluid mechanics, rotating equipment (pumps/blowers), and piping networks.

  • Working knowledge of international and local construction codes and safety standards.

• Soft Skills: Strong cross-functional coordination, problem-solving abilities, and clear written/verbal communication skills.
