Mechanical Design Engineer

Job description

Want to use your engineering skills to genuinely help the planet?

My client operates in the clean energy space, with a clear mission to significantly reduce carbon emissions across both residential and commercial environments.

They’re looking for a Mechanical Design Engineer to join the team and work across the full product life-cycle, covering design, development, engineering analysis and design for manufacture – seeing concepts through from initial idea to production.

This is an opportunity to play a hands-on role in developing real-world technology that makes a measurable environmental impact.

The Role

Working as part of a multidisciplinary R&D team, they will take ownership of mechanical design activities across new and existing products. This is a highly varied role, combining creative concept development with rigorous engineering analysis and practical manufacturing implementation.

They will be involved from early-stage ideation through prototyping, validation, and into full production - ensuring products are robust, cost-effective and optimised for manufacture and installation.

Key Responsibilities

• Design and engineering of new and existing products with a strong focus on Design for Manufacture (DFM)
• Selection of materials, manufacturing methods and production locations
• Creation and maintenance of bills of materials and parts lists
• Engineering analysis including stress and strain calculations, supported by FEA
• Conducting risk assessments and FMEA activities
• Evaluating and improving manufacturing, assembly, installation and servicing processes to reduce cost and increase reliability
• Hands-on prototype building, testing and design problem-solving
• Producing documentation for installation, servicing and maintenance regimes
• Ensuring compliance with relevant safety and testing standards (including CE marking and Machinery Directive considerations where applicable)
• Supporting ongoing engineering changes including substitute parts, suppliers and subcontractor management
• Managing assigned projects and work packages through to completion

What They’re Looking For

• 2:1 or above in Mechanical Engineering or related discipline (BEng or equivalent)
• Experience in a production or engineering design role within a manufacturing environment (SME experience highly beneficial)
• Strong 3D CAD skills (SolidWorks preferred)
• Good 2D CAD capability (SolidWorks preferred; AutoCAD beneficial)
• Experience with FEA and mechanical analysis
• Practical, hands-on ability to build and test prototypes
• Knowledge of MRP/ERP systems advantageous
• Experience working with subcontract manufacturers on bespoke assemblies desirable
• Understanding of structured DFM methodologies and Lean/5S/Kaizen/Poka-yoke principles beneficial
• Interest in expanding skills into programming, firmware, C+, or web-based tools welcomed
• Full right to work in the UK and a valid UK driving licence (or equivalent permitted licence)

Why Join?

• Work on technology that directly contributes to reducing global carbon emissions
• Full product lifecycle ownership – not just incremental design tweaks
• High-impact role within an agile and growing clean energy business
• Opportunity to influence product direction and manufacturing strategy
• A technically challenging environment with real-world engineering problems to solve

If they’re looking for a role where their mechanical engineering expertise translates into meaningful environmental impact - this is a rare opportunity to do exactly that.
