There is a lot to be said about the right culture in an Engineering Consultancy.

Stuffy, formal and over conservative … these maybe the terms traditionally used to explain the culture at your typical Engineering Consultancy, but that’s not what you will find at Wallace Design Group. In fact at WDG you will find a team of like minded professionals ready and willing to bounce ideas off each other, collaborating for the common goal of solving engineering problems for our clients.

We are experienced, open and inclusive offering a flexible workplace which assists with work/life balance.
