If you’re ambitious, innovative and eager to learn, we’ll provide the training, support and opportunities to help you develop.
The role
We’re looking for a Mechanical Design Engineer to support the development of new products from concept through to production, as well as the ongoing improvement of existing products. You’ll work across the full product lifecycle—helping translate requirements into practical designs, supporting testing and certification, and collaborating with internal teams and international manufacturing partners.
This is a hands-on role with opportunities to contribute to innovation, problem-solving, and continuous improvement.
What you’ll be doing
- Supporting new product development from early concept through to production design
- Contributing to the improvement of existing products by incorporating feedback from internal teams, customers, and partners
- Creating and maintaining technical design documentation, including drawings, specifications, and Bills of Materials (BOMs)
- Interpreting design requirements and helping define product specifications
- Designing mechanical components using 3D CAD tools
- Building and testing prototypes to validate designs
- Supporting product testing, certification, and type approval for UK and international markets
- Assisting with product launches, both internally and externally
- Supporting early installations and gathering feedback for further improvements
- Troubleshooting design and performance issues in existing products
- Adapting and customising products for new applications or markets
- Updating technical documentation in line with design changes and certification requirements
- Collaborating with overseas manufacturing partners to support production and quality
