We are seeking a Senior Mechanical Design Engineer to support the development of complex electro-mechanical equipment within a highly regulated engineering environment. This role involves the design, development and integration of mechanical assemblies and structures for advanced technology programmes, working within a multidisciplinary team of mechanical, electrical, systems and manufacturing engineers.

The successful candidate will be involved throughout the product lifecycle, from concept development through detailed design, verification, manufacture and design review activities.

Key Responsibilities

• Develop detailed 3D CAD models and engineering drawings for mechanical and electro-mechanical assemblies.
• Create and maintain engineering Bills of Materials (BOMs) and associated product definition data.
• Perform tolerance analysis and design assessments to ensure robust product performance.
• Conduct mass property calculations including weight, centre of gravity and balance considerations.
• Support design for manufacture and design for assembly activities throughout the development lifecycle.
• Design and develop structural components, housings, brackets and supporting mechanical assemblies.
• Participate in formal design reviews and technical assessment activities.
• Collaborate closely with systems, manufacturing, electronics, test and project engineering teams.
• Ensure designs comply with relevant industry and engineering standards.
• Support product verification, integration and development testing activities.
• Contribute to continuous improvement of engineering processes and design practices.

Essential Skills & Experience

• Degree qualified in Mechanical Engineering or a related discipline.
• Significant experience in mechanical design and development of complex engineering products.
• Strong 3D CAD experience, ideally using PTC Creo.
• Experience creating and maintaining engineering BOMs.
• Proven ability to perform tolerance studies and dimensional analyses.
• Experience completing mass property calculations and design assessments.
• Strong understanding of Design for Manufacture (DFM) and Design for Assembly (DFA) principles.
• Experience of structural mechanical design.
• Familiarity with engineering standards and controlled design environments.
• Experience working within multidisciplinary engineering teams.
• Ability to communicate technical information clearly at design reviews and stakeholder meetings.

Desirable Skills

• Experience of cable harness routing and electro-mechanical integration.
• Environmental sealing and gasket design experience.
• Experience within defence, aerospace, maritime or safety-critical industries.
• Understanding of product lifecycle management (PLM) and configuration control processes.
• Familiarity with qualification, verification and validation activities.
• Knowledge of manufacturing techniques including machining, fabrication and assembly processes.
