AI has rewritten the data centre design brief. Rack densities that were exceptional a few years ago are now the baseline, liquid cooling has moved from niche to default, and electrical design has to carry far more power per hall. The engineers who have designed for these densities are a small, sought-after group.

T4X searches for heads of design and engineering, technical directors and specialist leads for operators, hyperscalers, AI cloud providers, and the design firms, contractors and OEMs that serve them.
