Location: Flexible – can be based in various locations across the UK

What You’ll Be Doing:

As a Mechanical Design Engineer, you’ll take ownership of mechanical design activities across the full project lifecycle, with a focus on water and wastewater infrastructure. This includes involvement at all AMP cycle stages – from early feasibility and outline design through to detailed design, construction support, and commissioning.

Working within multi-disciplinary teams (PMEICA and Civils), you’ll produce and manage mechanical designs in accordance with our Business Management System (BMS), CDM regulations, and client specifications. Your input will directly support treatment works for both clean and wastewater – covering pumping stations, screening, pipework, sludge handling, filtration systems, and associated M&E elements.

Key responsibilities also include:

• Providing technical input for procurement and supporting site teams during installation and commissioning.
  
  
• Assisting in the management of sub-contractors and external consultants to ensure high-quality design outputs.
  
  
• Supporting project teams with scheduling, resource planning, and risk management where required.
  
  About You:
  
  
• HNC/Degree-qualified in Mechanical Engineering or a related discipline.
  
  
• Experience working across clean water, wastewater, or broader process engineering projects.
  
  
• Understanding of Health & Safety legislation and CDM 2015 regulations.
  
  
• Awareness of commercial processes and sub-contractor management.
  
  
• Familiar with project delivery practices such as programming and resource planning.
  
  
• Working towards, or open to working towards, membership of a professional body (e.g. IMechE).
  
  What We Can Offer in Return:
  
  With an order book exceeding £3.8 billion, you’ll join a well-established principal contractor delivering high-profile water infrastructure schemes across the UK. You’ll be part of a forward-thinking and supportive team that encourages continuous growth, innovation, and flexibility.
