Mechanical & Electrical Design Engineer

Water & Wastewater Infrastructure

If you enjoy seeing your designs make a real-world difference, keep reading.

This is a hands-on Mechanical & Electrical Design Engineer role where your work directly shapes water and wastewater treatment facilities — from pump stations and treatment plants to complex network infrastructure.

Demand is growing, projects are increasing, and this role has been created to support a busy and expanding portfolio of work. You'll be joining a team that values practical engineering, collaboration, and ideas that actually get implemented — not parked in a drawer.

If you want responsibility, variety, and the chance to influence how things are designed and delivered, this Mechanical & Electrical Design Engineer role gives you exactly that.

• 
  
• Design mechanical and electrical systems for water and wastewater assets including pump stations, treatment plants, pipelines and valves
  
• Produce high-quality detailed designs using CAD tools (AutoCAD, Revit, etc.)
  
• Work closely with civil, process and instrumentation engineers to deliver fully integrated solutions
  
• Manage your own design deliverables, ensuring quality, programme and budget requirements are met
  
• Ensure all designs comply with industry standards, regulations and health & safety requirements
  
• Engage with clients to understand requirements, explain technical solutions and support decision-making
  
• Contribute ideas that improve efficiency, sustainability and long-term performance of assets
  

This is a collaborative, roll-your-sleeves-up environment — you'll have the freedom to step beyond a narrow job description and genuinely influence outcomes.

• 
  
• Enjoy solving practical engineering problems, not just producing drawings
  
• Like working across disciplines and learning how everything fits together
  
• Are comfortable taking responsibility and managing your own workload
  
• Want your ideas to be heard and used
  
• Care about sustainable, well-thought-out design
  
• Enjoy variety — office design work mixed with site exposure
  

• 
  
• 3-5+ years' experience in mechanical and/or electrical design engineering
  
• Experience within the water or wastewater sector (highly desirable)
  
• A degree in Mechanical Engineering, Electrical Engineering or a related discipline
  
• Strong CAD capability (AutoCAD, Revit or similar)
  
• Knowledge of relevant water industry standards and regulations (e.g. WIMES, DSEAR, BS / EU standards)
  
• A practical, sustainability-focused mindset
  

Chartered or working toward professional registration is beneficial, but not essential.

• 
  
• A mix of office-based design work and site involvement
  
• Site work primarily across the South of England, with occasional nationwide travel
  
• A varied workload across multiple projects rather than being tied to one narrow area
  
• A team environment that values flexibility, collaboration and proactive engineers
  

• 
  
• Real ownership of design work from concept to delivery
  
• Direct impact on critical water infrastructure and sustainability outcomes
  
• A growing workload that offers long‑term stability and development
  
• Exposure to a wide range of projects and engineering challenges
  
• A culture where engineers are trusted, listened to, and supported
