Meet The Team

Noel Tovey-Grindlay

Managing Director

Noel has 8 years of experience in the design of complex interconnection systems in the defence sector including the land,  maritime and energy sectors. During this time Noel has gained the skills to take a system from a rough concept to top level interconnection schematics through to detailed cable harness design and 3D routing of complex systems in 3D CAD environments.

Having worked in the defence sector on a number of high profile projects has given him the background knowledge to identify and develop new products for the defence sector.

He has a vast amount of experience on a number of design tools whilst working on large scale defence projects including Zuken E3, HarnWare, Fusion 360, AutoCAD Electrical and Inventor.

As well as the design of systems Noel has also worked closely with a number of suppliers to deliver cable harness to meet the project requirements and ensuring they meet the quality requirements of the client and ensuring the delivery is on time and meets the programme schedule.

With these skills, there is no project that is too complex for Noel to handle.
