Responsibilities:

3D Modeling & Detailed Engineering

• Develop detailed 3D models of treatment plants, including Integration of mechanical equipment, tanks, vessels, pumps, filters, piping systems, valves, fittings and instrumentation.
• Translate P&IDs and engineering requirements into detailed piping, motors, instrumentation and valves layouts, and coordinated 3D models.
• Design piping routes, equipment arrangements, maintenance access, drainage and installation interfaces.
• Design piping supports, including support arrangements, details and load considerations, in coordination with structural engineers.
• Coordinate the 3D model with civil, structural, mechanical, electrical and instrumentation disciplines.
• Perform model reviews and clash detection.

Engineering Drawings & Documentation

• Prepare General Arrangement (GA) drawings, layouts, plans and sections.
• Generate piping isometric drawings and construction details.
• Prepare detailed drawings of tanks, vessels, columns and skids, including openings and connections.
• Prepare piping support drawings and details.
• Generate and validate Bills of Materials (BOM)
• Ensure consistency between 3D models, P&IDs, specifications and engineering drawings.

Engineering Standards & Infrastructure

• Establish, develop and maintain standardized 3D design procedures, engineering guidelines and drafting standards.
• Build and maintain a comprehensive 3D component library, including equipment, piping components, valves, fittings, instrumentation and piping supports.
• Develop and maintain AutoCAD Plant 3D catalogs, piping specifications (Pipe Specs), templates and component databases.
• Establish standardized project templates, drawing formats, naming conventions and model structures.
• Develop and maintain the digital design infrastructure, tools and workflows required for efficient and consistent engineering activities.
• Lead the implementation of standardized 3D design methodologies and best practices across engineering projects.

Training & Professional Development

• Lead technical training and knowledge transfer for engineers and designers in AutoCAD Plant 3D and 3D design methodologies.
• Develop training materials, technical guidelines and internal working procedures.
• Provide ongoing technical support, guidance and mentoring to engineering team members.

Requirements:

Education

• Bachelor's degree (B.Sc. or equivalent) in Mechanical Engineering – advantage.
• A degree in Environmental /Chemical /Water and wastewater Engineering or a related engineering discipline will also be considered.
• Alternatively, a Mechanical Engineering diploma or equivalent technical qualification, combined with at least 7–10 years of proven experience in 3D plant design and piping engineering.
• Previous experience with other 3D design and plant modelling software is a significant advantage, particularly for candidates who have worked as design engineers or piping designers with independent engineering responsibilities, rather than solely as CAD drafters.
• Preference will be given to candidates with a strong practical engineering background in piping design, industrial process plants, and water and wastewater treatment facilities.

Professional Experience

• Minimum 5 years of experience in 3D plant design and piping design.
• Proven experience in water and wastewater treatment plants, desalination facilities.
• Advanced proficiency in AutoCAD Plant 3D and AutoCAD.
• Excellent written and spoken English is mandatory, including the ability to conduct technical meetings, prepare engineering documentation and train engineers in English.
• Strong engineering mindset, problem-solving abilities, attention to detail and ability to work independently with international multidisciplinary teams.
