If you wish to stand out from the crowd, join us.  CO2nnsulting was set up because:

  • sustainability is not ticking the boxes;
  • we do not believe in filling in timesheets;
  • we would like to operate a politics-free office;
  • we can deliver quality work beyond expectation;
  • we do not have to align the quality of work with profit margin;
  • we would like to create a family of experts with a common goal;
  • we believe in working hard and playing even harder.

Here at CO2nnsulting, we look for people with passion, and not  those with an impressive transcript.   We look for young talents who have a long-term vision.   We have a proven track record of reformatting and transforming engineering and non-engineering graduates to solid consultants.  If you provide the  right mindset, we can provide the mentoring.
