Create, review and approve 3D CAD models, drawings and bills of materials in line with company standards
Produce and review design assurance documentation, including calculations, reports, test procedures and analyses
Support design investigations, root‑cause analysis and risk reduction activities to mature products and concepts
Act as a technical authority, supporting design reviews and approving solutions produced by other engineers
Interface across disciplines including mechanical, stress, thermal, V&V, industrialisation, configuration and quality
Provide technical guidance, mentoring and informal leadership to engineers within the project team
Support project reporting, milestone delivery and KPI achievement

Degree in Mechanical, Automotive or Aeronautical Engineering (or equivalent experience)
Strong experience delivering mechanical design work packages in a regulated engineering environment
Proven background in rotating machinery (shafts, bearings, seals, housings, structures)
Solid understanding of engineering materials and manufacturing methods
Substantial experience using 3D CAD tools for electromechanical design
Strong written and verbal communication skills
Ability to plan, prioritise and deliver work under tight project deadlines

Desirable:

Experience with high‑speed motors or power generation systems
