I work for a small engineering company that manufactures and maintains industrial chillers. They're sort of like a cooling system for large equipment. My official role is an administrator, though I predominantly deal with the supply of spare parts, and organising technicians to sites. I'm actually undertaking a technical degree in engineering so that I could potentially be more hands on.
What sort of studies are you doing at university?
And if you ever want more advice about GMing, or want to bounce ideas, feel free to ask.
