What we are looking for:

We are looking for someone with a B.S/B.E./B.A degree in a Mechanical Engineering discipline, and at least 10 years designing mechanical systems for data centres and knowledge of AI / HPC data centres. You should also have:

  • Mastery of ASHRAE TC 9.9, liquid-cooling best practices and ISO 14644 cleanliness classes

  • Strong vendor network across chillers, pumps, manifolds and coolant suppliers
  • PE/Chartered Engineer or equivalent credential preferred

What’s in it for you?

This is a fantastic opportunity to join a small, highly motivated team providing world-class supercomputing experience to its customers.
