Senior Mechanical Engineer Water Treatment EPC Projects

About the Role

Burjline Builders is seeking a Senior Mechanical Engineer to join their team in Riyadh. This full-time role focuses on mechanical design, equipment engineering, and fabrication for industrial water treatment, desalination, and wastewater treatment EPC projects. The ideal candidate will possess hands-on experience in mechanical calculations, pressure vessel and tank design, piping systems, fabrication drawings, and equipment specifications, and will be capable of independently managing mechanical engineering deliverables.

Key Responsibilities

• Perform mechanical design and engineering for water and wastewater treatment equipment and packaged systems.
• Prepare and review General Arrangement Drawings (GADs), fabrication drawings, mechanical datasheets, and equipment specifications.
• Design and review pressure vessels, storage tanks, filters, skid-mounted equipment, and piping systems.
• Perform mechanical calculations for vessels, tanks, supports, nozzles, pumps, and equipment foundations.
• Review piping layouts, isometrics, material specifications, and equipment interfaces.
• Coordinate fabrication activities, vendor drawings, welding documentation, inspections, FAT, and hydrotesting.
• Prepare material take-offs (MTOs), bills of materials (BOMs), and technical procurement documents.
• Support site installation, pre-commissioning, commissioning, and final documentation.

Qualifications and Experience

• Bachelor’s degree in Mechanical Engineering.
• 8–10+ years of relevant mechanical design and engineering experience, preferably in water treatment EPC projects.
• Strong knowledge of pressure vessel design, process piping, storage tanks, and industrial equipment fabrication.
• Familiarity with ASME Section VIII, ASME **, API 650, AWWA, and relevant ASTM standards.
• Experience with GRP/FRP tanks and piping systems is highly desirable.
• Proficiency in AutoCAD and 3D engineering tools such as Plant 3D, SolidWorks, or equivalent.
• Strong understanding of welding, NDT, hydrotesting, material selection, and corrosion protection.

Candidate Profile

This position is suited for a hands-on mechanical design engineer with a focus on design deliverables. Experience with an EPC contractor, pressure vessel manufacturer, skid fabricator, or water treatment equipment OEM will be considered a strong advantage. Candidates whose experience is primarily limited to maintenance, site supervision, or CAD drafting are not the primary focus for this design-oriented role.

Work Type and Location

This is a full-time position based in Riyadh. Salary information will be discussed during the interview process.
