R&D Mechanical Design Engineer

🏆 Queen's Award for Innovation recipient - one of the UK's most prestigious business honours.

The Role

This is a position sitting within our R&D team, reporting to the R&D Team Lead. You'll take ownership of the mechanical design of our sensor housings and measurement devices from early concept through to production-ready builds. You will be working across waterproofing, materials selection, prototyping, and iterative improvement.

This is a hands-on, independent role that suits someone who thrives solving real engineering problems with clean, considered design.

What You'll Be Doing

• Designing and developing waterproof housings and enclosures for electronic sensor equipment (IP67 and above, including subsea environments)
• Taking designs from concept to prototype using a variety of manufacturing methods and partners
• Conducting structured tests and maintaining thorough, documented results
• Ensuring designs are production-ready: optimised for manufacture, repeatability and cost
• Driving continuous improvement based on customer feedback and in-house testing
• Collaborating with the wider R&D team and third-party suppliers to develop and manufacture components
• Contributing to expanding the team's in-house simulation and testing capabilities
• Selecting the best materials for demanding environments (e.g. seawater, freshwater, chemicals, vibration and shock)

What We're Looking For

• Demonstrable experience in mechanical design for physical products, ideally sensors, instrumentation or similar precision devices
• Strong 3D CAD skills (Fusion 360, SolidWorks)
• Proven track record designing for waterproofing and environmental protection
• Experience taking products from prototype to production-ready designs
• Methodical approach to testing, documentation and iteration
• Comfortable working independently

Desirable: Injection moulding design experience; familiarity with sealing technologies, gasket design, optics and optical systems.
