• Manage mechanical engineering packages from design through to installation, commissioning and handover
• Review designs, drawings, specifications and technical documentation to ensure constructability and compliance
• Coordinate the procurement of mechanical equipment, materials and specialist packages
• Work directly with suppliers, subcontractors and construction teams to resolve technical and site issues
• Support the planning and delivery of mechanical installation works, including pumps, pipework, valves, treatment equipment and associated systems
• Provide engineering support during construction, testing and commissioning
• Assist with project programming, cost control, forecasting and commercial management
• Manage QA documentation, inspections, ITPs, technical queries and project close-out requirements
• Build strong working relationships with clients, consultants, suppliers and subcontractors
• Contribute to the safe, environmentally responsible and successful delivery of projects

This is an opportunity to build your career with a specialist infrastructure contractor, gaining hands-on experience across the complete project lifecycle while helping deliver critical water infrastructure across Western Australia

 You Will Bring:

• Experience in project delivery, construction or a related engineering environment A degree or relevant qualification in  Mechanical Engineering
• Strong mechanical engineering knowledge with a practical, solutions-focused approach
• The ability to manage competing priorities and deliver to project deadlines
• Strong communication skills and the ability to build relationships with clients, subcontractor, suppliers and project teams.
