About

I work where disciplines meet.

Portrait of Steve Hammond

I am most useful when a design is incomplete, the interfaces are messy and someone needs to connect CAD, analysis, suppliers, testing and production.

Over more than 20 years, I have worked across electric and autonomous vehicles, aerospace, rotary engines, manufacturing automation and medical products. The common thread is practical systems thinking: finding the hidden dependencies and turning them into something a team can build and support.

BEng (Hons), Integrated Engineering with Automotive Studies, Sheffield Hallam University.
