The Next Generation of EM3

At EM3, we are continuously growing and expanding, and this wouldn’t be possible without the smart and committed individuals who make up our team. We truly believe in investing in our team, particularly the younger generation. For this reason, we actively hire graduates from an array of universities and institutes around the country. This year alone 8 new graduates have joined our team from MTU, UCC, LIT and NUIG.  We are committed to investing in a younger workforce to allow us to tackle real and important climate and environmental issues around the world.
