As part of the Design Team, the Senior Mechanical Design Engineer will lead the design and development of mechanical systems for water and wastewater treatment projects for various clients This role involves taking technical responsibility for mechanical engineering designs, ensuring they meet project, regulatory, and client requirements while coordinating with multidisciplinary teams. The Senior Mechanical Engineer will mentor junior engineers, manage the design process from concept to completion, and provide expert input throughout project delivery. They will also ensure that designs promote safety, sustainability, and efficiency, and are completed within budget and on schedule. Lead the mechanical design process for water and wastewater treatment projects, ensuring technical excellence and compliance with regulatory standards. Develop detailed mechanical designs including 3D Models, schedules, equipment layouts, mechanical specifications, and calculations for pumps, pipelines, tanks, valves, and filtration systems. Ensure designs comply with industry regulations, standards (including HSE and environmental regulations), and client specifications, while focusing on energy efficiency and sustainability. Collaborate with multidisciplinary teams (civil, EICA and process) to ensure seamless integration of mechanical systems with other project components. Review and approve technical design documents, including mechanical drawings, specifications, equipment schedules, and reports. Conduct technical reviews and design audits to ensure project quality and adherence to both internal and external standards. Provide leadership during the procurement, installation, and commissioning phases, offering expert mechanical design support to ensure system functionality and operational safety. Manage project risks related to mechanical design, conducting design risk assessments, and proposing mitigation strategies. Mentor and support junior mechanical engineers, providing technical guidance and championing professional development within the team. Liaise with clients, contractors, and regulatory authorities to ensure the mechanical design meets project objectives and aligns with stakeholder expectations. Stay up to date with the latest developments in mechanical engineering, materials, and technologies to drive innovation in mechanical system designs. Participate in design reviews, value engineering, and sustainability initiatives to improve project outcomes and reduce costs.
