Senior Water/Wastewater Treatment Engineer
We are seeking a Senior Water/Wastewater Treatment Engineer to lead the planning, design, and delivery of complex water and wastewater treatment projects. This role will involve developing practical, cost-effective, and sustainable solutions across the full project lifecycle, from feasibility and concept development through detailed design, construction support, commissioning, and operational optimisation. You will work with multidisciplinary teams, clients, contractors, regulators, and other stakeholders to ensure projects meet technical, environmental, safety, programme, and budget requirements.
Key responsibilities will include preparing and reviewing process designs, treatment calculations, technical specifications, drawings, reports, and procurement documentation. You will assess existing treatment assets, identify performance improvements, and develop solutions for water quality, process efficiency, resilience, and regulatory compliance. The role will also involve managing technical workstreams, mentoring engineers and junior staff, contributing to bids and project proposals, reviewing contractor submissions, supporting site activities, and providing technical guidance during construction and commissioning. You will be expected to identify project risks, resolve complex engineering issues, and communicate recommendations clearly to both technical and non-technical audiences.
Applicants should hold a degree in chemical, civil, environmental, process, or a related engineering discipline, together with substantial experience in water or wastewater treatment design and delivery. Strong knowledge of treatment processes, hydraulic principles, process modelling, relevant standards, and environmental regulations is essential. Experience with design software, technical assurance, project management, and working within regulated infrastructure environments will be highly valued. Professional registration or a clear commitment to achieving it is desirable. The successful candidate will be organised, commercially aware, and confident leading technical discussions, with the ability to manage competing priorities and build effective relationships. A commitment to health and safety, quality, sustainability, and continuous improvement is essential.
