• Degree in Mechanical Engineering, Product Design Engineering, or a related discipline.
• 10+ years of product development experience with significant experience in helmet systems, PPE, safety equipment, or other wearable products.
• Demonstrated experience leading products from concept through certification and production, with direct experience of ANSI Type I, ANSI Type II, and EN397 programmes.
• Expert‑level CAD capability (Solid Works or equivalent) and experience working directly with certification bodies, testing laboratories, and external manufacturing partners.

• Wearable electronics integration & thermal management
• Impact protection systems & structural safety design
• Injection moulding, tooling & production scale‑up
• Strong technical leadership & stakeholder management
• International compliance & certification programmes
• Hands‑on, practical approach to engineering challenges
