Senior​/Principal Mechanical Engineer - Water

Senior / Principal Mechanical Engineer - Water

Access Talent Group are looking for experienced Senior Mechanical Engineers to join a growing water engineering team and play a key role in delivering reliable, efficient solutions across the water and wastewater sector. This position offers the opportunity to take ownership of complex engineering designs and support the delivery of major infrastructure projects, including treatment facilities, pumping stations, and transmission systems.

The role is ideally suited to candidates based in Leeds or Cardiff, though applications are welcomed from several UK locations, including Birmingham, Manchester, Sheffield, and Liverpool, with flexible working arrangements available.

You will work on technically demanding, high-value projects within long-term delivery frameworks for major UK water utility providers. The role involves leading key mechanical engineering activities, applying technical expertise throughout the project lifecycle, and supporting the development of less experienced engineers. Building effective working relationships with clients, partners, and internal teams is a core part of the position.

As a Senior Mechanical Engineer, you will lead mechanical design and project delivery from feasibility through detailed design and construction. You will provide technical leadership to multidisciplinary teams, focusing on water and wastewater treatment processes, pumping solutions, and pipework systems. Responsibilities include reviewing and overseeing design outputs, ensuring compliance with industry standards, and maintaining high technical quality across all stages of delivery.

The role includes direct engagement with clients to define technical solutions, manage programme and cost constraints, and support successful project outcomes. You will also contribute to business development activities, including bid preparation, proposal development, and participation in technical discussions with clients. Digital engineering tools such as BIM and Plant 3D will be used to support efficient, coordinated design, alongside a strong emphasis on innovation, quality, and operational efficiency.

These positions are suited to senior-level engineers with demonstrable experience in the water sector, particularly in treatment works, pumping installations, and mechanical systems. You should be self‑motivated, adaptable to project and client demands, and comfortable working within multidisciplinary teams to deliver high‑quality engineering solutions.

• Proven experience delivering mechanical designs within the UK water utilities sector, including treatment facilities and pumping systems
• Chartered Engineer (CEng) status with IMechE or a relevant professional institution, or actively working towards chartership
• Strong understanding of current mechanical design standards and best practices within the water industry
• Experience using digital design tools such as BIM and Plant 3D
• Effective communication skills and the ability to collaborate across multidisciplinary teams
• A results‑focused approach, with the ability to manage competing priorities and deliver work to time and quality targets
• Employee ownership
• Extensive benefits package
• 37.5 hours a week
