Product / Mechanical Design Engineer (Opto-Mechanical Systems)
A growing technology company developing advanced sensing and instrumentation products is seeking a Product / Mechanical Design Engineer to join its multidisciplinary R&D team. The organisation builds next-generation hardware systems that combine mechanical, optical, and product-focused engineering, with a strong emphasis on hands-on development and rapid iteration.
This is an opportunity to join a fast-moving development environment where you’ll contribute directly to real-world products, working across concept, design, prototyping, and validation. The role is primarily based on-site to support collaboration and hands-on system development, with some flexibility for hybrid working where appropriate.
The Role
You will play a key part in the development of complex hardware products, with a particular focus on opto-mechanical systems and productised hardware. The role blends mechanical design, practical prototyping, and cross-disciplinary collaboration, working closely with engineers from adjacent domains.
You’ll be expected to take a systematic, hands-on approach to problem solving and to operate effectively in a dynamic, evolving product development environment.
Key Responsibilities
* Design and develop mechanical and opto-mechanical hardware for product-focused systems
* Produce detailed 3D CAD models, assemblies, and technical drawings
* Support materials selection and manufacturing process decisions
* Build and iterate prototypes using in-house and external fabrication methods (e.g. 3D printing, machining, laser cutting, cable assembly)
* Contribute to system integration, testing, and validation activities
* Create and maintain technical documentation including specifications, drawings, BOMs, and build instructions
* Work closely with cross-functional teams to deliver robust, manufacturable product designs
* Support continuous improvement of designs, processes, and documentation
Required Qualifications & Experience
* Degree, HND, or equivalent industrial experience in Mechanical Engineering, Engineering, or a related discipline
* Around 3+ years’ experience in product development within a multidisciplinary R&D or product development environment
* Demonstrated experience developing opto-mechanical or precision hardware systems
* Strong grounding in mechanical design principles, materials, and common manufacturing processes
* Proficiency in 3D CAD (SolidWorks or similar), including complex assemblies and detailed drawings
* Hands‑on prototyping experience (e.g. SLA/FDM 3D printing, basic machining, laser cutting, cable assembly)
* Comfortable working in a fast‑paced, evolving development environment
* Experience producing clear technical documentation (specifications, test procedures, build instructions, revision control, BOMs)
* Background in a start‑up, scale‑up, or new product development environment
* Exposure to product design or user‑focused design considerations
* Working knowledge of electronics, firmware, or adjacent engineering disciplines
What’s on Offer
* Opportunity to work on cutting‑edge, real‑world hardware products
* High‑impact role in a growing, technology-focused organisation
* Hands‑on involvement across the full product development lifecycle
* Collaborative, multidisciplinary engineering environment
* Strong scope for technical growth and ownership
