Review designs for accuracy, tolerancing, and completeness.
Monitor progress, workload, and deliverables for design work packages.
Engage with suppliers, customers, and partners to support design activities.
Key Skills and Experience:
Strong foundation in mechanical design and engineering principles.
Proficiency in CATIA V5 (V6 desirable) and PLM systems such as ENOVIA.
Experience with Design for Manufacture (DfM) and engineering change control.
Solid understanding of drawing standards (e.g. BS 8888) and GD&T.
Experience creating and managing BoMs.
Strong communication and stakeholder management skills.
Competence with tools such as Excel and PowerPoint.
Desirable Experience:
Background in the space or aerospace sector.
Experience working in multidisciplinary project environments.
Exposure to customer and supplier interactions.
Familiarity with advanced CAD modules such as sheet metal, pipe routing, harnessing, composites, kinematics, or additive manufacturing design.
Security Clearance Requirement:
Due to the nature of the work that we do at Thales, many of our roles are subject to security restrictions. This role requires Security Clearance (SC). It would be advantageous if currently held, however, if not currently held, it is a requirement that the successful applicant undergo, achieve, and maintain SC Clearance prior to commencing employment.
