About CJM

Independent engineering. Direct collaboration.

Design capability for manufacturers who need considered technical work and a clear point of contact.

Who we are

Built to support your team.

CJM Engineering is an independent design engineering practice founded by Cillian McCay in Northern Ireland. We work with manufacturers on mechanical and electrical design, CAD, scanning, and rapid prototyping.

Whether you need a component developed from scratch, an existing design modified, or an old part reconstructed, the work begins with the requirements and ends with agreed deliverables your team can use.

Cillian holds a BEng in Mechatronic Engineering and brings over five years of industry experience. Projects are scoped to fit the task, with direct communication throughout.
