Are you a Junior Mechanical Design Engineer with a background in construction, manufacturing or a similar field, looking to start your career in a hands–on role where you'll receive full training and clear progression?

Join a specialist engineering company that is investing heavily in innovation and R&D. You'll be involved in developing bespoke roofing systems, working alongside Tier 1 contractors and architects on technically challenging projects – with the opportunity to physically build and test what you design.

In this junior role, you'll gain exposure to R&D projects from concept through to manufacture, working across CAD, prototyping, fabrication, and testing. This is not just a desk–based design role – you'll be involved in building and modifying physical prototypes in a workshop environment. Based in the Royston office, you'll collaborate closely with the R&D Manager and the wider business to deliver evidence‑led product development and grow your technical skills.

This role is ideal for a Junior Mechanical Design Engineer with a construction, manufacturing, or practical engineering background who enjoys hands–on engineering work and wants early ownership of projects in a fast–paced, innovative environment.

• Support early–stage concept development and feasibility assessments
• Assist in designing bespoke construction solutions using 2D and 3D CAD (AutoCAD / Inventor)
• Support prototype production, fabrication, and assembly of metal components
• Work with workshop tools and fabrication processes to build and modify models
• Assist with internal testing for functionality, structural performance, and weathering integrity
• Coordinate with external testing providers to ensure compliance with industry standards
• Help develop performance criteria, technical specifications, and summary reports

• Junior Mechanical Design Engineer with a background in Construction, Manufacturing, or similar
• Hands–on engineering experience (e.g. machining, fabrication, sheet metal, welding, workshop projects, Formula Student, apprenticeships, or similar)
• Comfortable working with metal components and physical assemblies
• Experience with AutoCAD and/or Autodesk Inventor
• Commutable to Royston
