Job Description

Senior Mechanical Design Engineer

Are you an experienced Mechanical Design Engineer looking to take ownership of complex, high-precision products from concept through to manufacture? This is an exciting opportunity to join a leading engineering and manufacturing business working on innovative electromechanical systems used globally.

About the Role

You’ll play a key role in designing and developing advanced mechanical assemblies involving movement, motors, sensors, mechanisms, enclosures, precision components, heating and cooling systems, and other complex subsystems. This is a hands-on, full-lifecycle design role where you will work closely with production, electronics, testing and manufacturing teams to deliver robust, manufacturable, and high-quality products.

Key Responsibilities of the Mechanical Design Engineer:

• Lead mechanical design activities across the full product life-cycle — from concept and feasibility through to detailed design, prototyping, testing, and production release.
• Design complex precision mechanisms, electromechanical assemblies, drive systems, and sensor-integrated components.
• Develop cases, housings, frames, and thermal management solutions for reliability and performance.
• Apply Design for Manufacture (DfM) and Design for Assembly (DfA) to optimise production efficiency.
• Support build, test, validation, and production troubleshooting, ensuring products meet quality and regulatory standards.
• Create detailed CAD models, engineering drawings, BOMs, and documentation for prototypes and production.
• Collaborate cross-functionally with electronics, software, quality, and operations teams.

About You as a Mechanical Design Engineer:

• Strong mechanical design experience within an engineered product environment (e.g. electromechanical, automation, robotics, instrumentation, or similar).
• Proven background designing systems incorporating motors, actuators, sensors, mechanisms, and thermal management.
• Confident working with precision components, tight tolerances, and complex assemblies.
• Strong 3D CAD skills (any major platform).
• Excellent problem-solving skills, creativity, and engineering rigour.
• Comfortable working in a fast-paced environment with responsibility for taking products from concept to manufacture.

Why Apply?

• Work on technically challenging, meaningful engineering projects.
• Join a collaborative, forward-thinking team where your ideas matter.
• Genuine opportunities for progression and ongoing professional development.
