One signal

NVIDIA validation engineer Sakeena Fiza says her team tests AI hardware by trying to break it before customers have to rely on it. Her work covers everything from firmware and thermal behaviour to power integrity, high-speed signalling and manufacturing issues across systems that can scale from a board to a rack and cluster.

Why it matters

In NVIDIA’s account, the job is a reminder that AI infrastructure is not simply a contest to produce a quicker GPU. Engineers must make vast collections of components behave as one system under stress, sometimes tracing a failure to something as small as an overtightened screw or dust in a customer facility. That is a useful behind-the-scenes signal from the company’s Rubin-era hardware push: reliability work is where the grand AI factory meets the very ung grand reality of physics. Should chip companies spend more effort explaining this engineering layer, or is the hardware story destined to remain a footnote to the model race?
