Mechanical Engineering | MEICA | Water & Wastewater | Process Plant | Pipework | AMP Projects Want to Design Engineering Solutions That Actually Make It to Site? Join a growing multidisciplinary engineering business where you'll see your designs move from concept and calculations through to installation on critical water and wastewater infrastructure. We're looking for a proactive and technically strong Mechanical Design Engineer to join CHG Electrical, supporting the design and delivery of mechanical engineering solutions across clean and dirty water treatment sites. From pumps, pipework and valves to tanks and wider process plant, you'll develop practical mechanical solutions that integrate with civil, electrical and ICA systems and support successful MEICA delivery. If you've developed your mechanical design experience within water, utilities or infrastructure and want greater project exposure, collaboration and long-term progression, we'd love to talk. The Role at a Glance Mechanical Design Engineer Sheffield - Hybrid Working Available (1-2 days home based) £45,000 - £50,000 + Performance Bonus Full Time | Permanent Flexitime | 25 Days Holiday + Bank Holidays | CPD & Training Projects: Water | Wastewater | Utilities | AMP Infrastructure | MEICA Design: Pumps | Pipework | Valves | Tanks | Process Plant | P&IDs | GA Layouts Software: AutoCAD | Inventor | Pipework / Process Design Tools Knowledge: WIMES | CDM | Sewerage Sector Guidance | Mechanical / Process Standards Essential: Full UK Driving Licence Who We Are Founded in Sheffield in 2004, CHG Electrical has more than two decades of engineering heritage. Built on strong electrical engineering foundations, the business has evolved into a multidisciplinary engineering partner delivering complex projects across water utilities, rail, steel and manufacturing. Today, our capabilities span MEICA, EICAT, civil engineering, control-panel design and manufacture, automation, software and digital transformation. We support projects from initial design through installation and commissioning to long-term maintenance, combining practical, hands-on engineering experience with modern technology and intelligent thinking. Throughout that evolution, the principles behind CHG have remained consistent: technical excellence, exceptional quality, safe delivery and trusted long-term relationships. It's this proven heritage, combined with our ambition to keep innovating, that enables us to deliver reliable, future-ready solutions for some of the UK's most important infrastructure. The Opportunity This is an opportunity to become an important part of CHG's growing design capability, developing the mechanical engineering solutions that sit at the heart of water and wastewater infrastructure projects. You'll produce detailed layouts, pipework designs, equipment specifications and calculations to support the installation of process plant and MEICA equipment across clean and dirty water treatment sites. Working alongside civil, electrical and wider engineering specialists, you'll ensure mechanical designs don't simply work technically, but are practical to build, integrate effectively with other disciplines and meet the requirements of the project and water company. You'll also remain involved as projects move onto site, providing technical support during construction, resolving design queries and helping take your designs through to successful handover. Where You'll Make an Impact Design Practical Mechanical Solutions • Prepare mechanical engineering designs, drawings and calculations covering pumps, pipework, valves, tanks and process plant. • Support the development of P&IDs, GA layouts and equipment schedules for project mobilisation. • Interpret process flow information and equipment specifications to develop effective engineering solutions. Bring Engineering Disciplines Together • Coordinate with civil, electrical and wider project teams to ensure mechanical desi
