Role Overview

Our client is seeking a Mechanical Design Engineer to support the design and delivery of specialist water and wastewater treatment installations.

The role centres on developing detailed 3D models and engineering drawings using Autodesk Revit, alongside producing technical documentation and supporting project coordination. Working closely with project management and installation teams, you will help translate engineering concepts into practical, buildable solutions.

Key Responsibilities

• Develop and maintain 3D Revit models and 2D engineering drawings for mechanical and electrical plant installations.
• Produce equipment layouts, pipework arrangements, general arrangement drawings and fabrication details.
• Interpret engineering specifications, P&IDs and site information to deliver accurate, coordinated designs.
• Prepare and maintain equipment schedules, material take-offs, bills of materials and supporting technical documentation.
• Identify design clashes, installation constraints and potential engineering risks.
• Liaise with project managers, contractors and suppliers to resolve technical queries and support project delivery.
• Undertake occasional UK site visits for surveys, dimensional checks and installation support.
• Ensure all drawings and documentation meet relevant engineering standards and project requirements.

Candidate Profile

• A practical, proactive approach with the ability to work independently and collaboratively.
• Strong attention to detail, organisation and problem-solving skills.
• Good understanding of mechanical engineering principles, equipment layouts and installation requirements.
• Experience preparing engineering schedules and technical documentation.
• Working knowledge of AutoCAD and Microsoft Office, particularly Excel.
• At least 2 years’ practical experience using Autodesk Revit, ideally within mechanical, process or plant engineering.
• Ability to interpret technical drawings, specifications and P&IDs.
• Experience producing detailed 3D models and 2D engineering drawings.
• Willingness to travel occasionally to UK project sites.

Desirable: Experience in water treatment, wastewater, utilities or process engineering; familiarity with pumps, valves, pipework, fabrication and BIM principles.
An HNC, HND or degree in Mechanical Engineering, Building Services or a related discipline would be advantageous, although relevant practical experience will also be considered.


Role would be contracted to 40 hours per week, Monday - Friday. Primarily office based.
