RS Hydro

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 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, Solid Works) 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 if you have: injection moulding design experience familiarity with sealing technologies, gasket design, optics and optical systems.
