Senior Mechanical Design Engineer

Location: Glasgow, On-site

Employment Type: Full-time, Permanent

We are seeking an experienced Senior Mechanical Design Engineer to join our clients multidisciplinary engineering team. This is a hands-on, technically influential role working across a diverse portfolio of innovative products in sectors such as optical systems, imaging, industrial instrumentation and electro‑mechanical technologies.

You’ll work across the full product development lifecycle — from concept and detailed design through to prototyping, verification and manufacture — and play a key role in shaping mechanical design direction across multiple projects.

The Role

This position suits a rounded, versatile mechanical engineer with strong practical design capability and broad manufacturing knowledge. Projects vary significantly, so the ideal candidate will be comfortable switching between technologies, industries and engineering challenges.

A particularly important area is plastic product design and injection moulding, which is one of the most common and technically demanding manufacturing processes used across their projects.

Key Responsibilities

*

Lead mechanical design projects from concept through to manufacture.

*

Develop mechanical architectures, detailed designs, assemblies and manufacturing drawings using CAD.

*

Act as a mechanical design authority, providing technical leadership across projects.

*

Design products with strong DFM/DFA principles, materials knowledge and manufacturing insight.

*

Collaborate closely with electronics, optics, software and other engineering disciplines.

*

Support prototyping, testing, design reviews and iterative development.

*

Provide technical input on manufacturing approaches and liaise with external suppliers.

*

Mentor junior and mid-level engineers.

*

Contribute to project planning, estimating and technical problem-solving.

Experience Required

*

Strong experience in mechanical design and product development.

*

Excellent hands-on CAD capability (SolidWorks, Creo, Inventor, NX or similar).

*

Strong understanding of manufacturing processes and Design for Manufacture.

*

Practical experience with plastic component design and injection moulding is highly desirable.

*

Experience across a range of manufacturing technologies:

*

Injection/rotational moulding and overmoulding

*

Vacuum casting / soft tooling

*

3D printing

*

Casting, extrusion and metal forming

*

Machining

*

Strong understanding of materials selection, tooling and manufacturing considerations.

*

Comfortable working across multiple projects and multidisciplinary teams.

*

Ability to provide technical leadership and mentor other engineers.

*

Experience with FEA/CFD, precision engineering, medical devices, optical systems or instrumentation is advantageous.

Why Apply?

This is an opportunity to join a highly skilled company where no two projects are the same. You’ll work on innovative products, influence mechanical design from concept through to manufacture and gain exposure to a wide range of technologies — all while playing a key technical role within a collaborative engineering team.
