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

• Lead mechanical design activities across the full product life‑cycle— from concept generation 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

• 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.

If you’re a Senior Mechanical Design Engineer who thrives on solving complex mechanical challenges and driving product innovation, we’d love to hear from you.
