Senior Mechanical Design Engineer

Job Purpose 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. Job Responsibilities 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. Candidate Specification Personal Attributes Strong leadership and mentoring abilities, with a track record of managing and guiding engineering teams. Excellent problem-solving skills with a focus on delivering innovative, efficient, and cost-effective mechanical solutions. Highly organised, with the ability to manage multiple projects simultaneously while maintaining high standards of accuracy and quality. Strong communication skills, with the ability to present technical information clearly to clients, team members, and stakeholders. A collaborative team player, open to feedback and willing to work across disciplines to deliver the best project outcomes. Technical Specification Experience Required 7-10 years of experience in mechanical design engineering, preferably within the water or wastewater industry. Proven experience designing water and wastewater treatment projects, working with multidisciplinary design teams. Strong knowledge of mechanical equipment used in water treatment, such as pumps, piping systems, valves, blowers, and filtration systems. Strong understanding of relevant industry standards, codes, and regulations (HSE, environmental standards, etc.) for mechanical systems in water treatment. Experience in mechanical system commissioning, including troubleshooting and optimisation during installation. Essential Qualifications Bachelors degree in Mechanical Engineering or related discipline. Chartered Engineer (CEng) status or actively working towards it. Proficiency in mechanical design tools and software, such as AutoCAD, SolidWorks, or similar programs. Desirable Qualifications Masters degree in Electrical, Control, or Automation Engineering. Familiarity with BIM (Building Information Modelling) and other advanced digital design tools. Experience in sustainable design practices, including energy-efficient mechanical systems and life-cycle cost analysis.
