Senior Mechanical Design Engineer

Piper Maddox are supporting a global aerospace engineering organisation with the hire of a Senior Mechanical Design Engineer to join their R&D Technical function in Buckinghamshire. The business is a recognised leader in aircraft electrical systems and is playing a central role in the electrification of aviation, spanning power generation, distribution, motors and hybrid-electric propulsion technologies. The UK site is a key engineering hub focused on smart motor and power generation technologies, supporting both established aerospace platforms and next-generation electromechanical systems. This is a senior-level mechanical design position with real ownership. You will lead and deliver engineering work packages across R&D and R&T programmes, developing robust mechanical solutions for rotating electrical equipment — ensuring designs are technically sound, manufacturable, cost-conscious and aligned to programme milestones. The role blends hands-on design responsibility with technical leadership and cross-functional coordination. You’ll work closely with Mechanical Design, Stress & Thermal, Industrialisation, Supply Chain, V&V and Quality teams to ensure mature and robust engineering solutions are delivered against programme targets. This is a technically influential position within a business heavily invested in future propulsion and electrification technologies. It offers the opportunity to operate at a senior engineering level while remaining hands-on in product development.
