As a Design Manager – Mechanical Infrastructure, you will lead the multidisciplinary mechanical design delivery for complex water and wastewater infrastructure projects, including pump stations, water treatment plants (WTPs), wastewater treatment plants (WWTPs), desalination systems, and associated mechanical/process systems.
You will be responsible for driving design integration, technical excellence, quality assurance, constructability, risk management, and programme certainty across all stages of project delivery—from concept through detailed and construction design.
Working closely with Project Managers, Discipline Leads, and Sector/Regional Leadership, you will plan, coordinate, and assure the technical execution of mechanical design packages, while mentoring and developing engineers across global teams.
Key duties include:
- Lead and manage mechanical design for water/wastewater pump stations, treatment plants, and associated mechanical/process systems.
- Develop project-specific mechanical design strategies ensuring multidisciplinary integration, alignment with project requirements, and risk mitigation.
- Oversee preparation and coordination of mechanical deliverables:
- Equipment sizing & selection
- Mechanical design calculations
- Pumping system calculations & hydraulic checks
- P&IDs, equipment layouts, plant general arrangements
- Mechanical data sheets and specifications
- Review and validate vendor documents, datasheets, and shop drawings; ensure integration with overall design.
- Lead mechanical engineering inputs for Design for Design‑Build (D for DB) and EPC delivery models: constructability, staging, installation methodology, O&M requirements.
- Support and lead HAZOP/HAZID, value engineering, risk workshops, failure mode assessments, and operability/maintainability reviews.
- Manage and own key design management documents:
- Project Responsibility Matrix
- Basis of Design
- Overall Design Programme
- Schedule of Deliverables
- Design Risk Register
- Design Change Register
- Coordinate with process, civil, electrical, ICA, BIM, structural, and architectural teams for holistic design delivery.
- Engage with clients through workshops, presentations, design reviews, and technical clarifications.
- Ensure design outputs comply with quality standards, codes, project specifications, and HSE requirements.
- Support the preparation of technical proposals, LOE estimates, design execution plans, and project scheduling.
- Mentor, coach, and provide performance feedback to engineers to strengthen organisational capability.
- Collaborate with global delivery centres to ensure consistent design practices and effective resource utilisation.
