Fiza says her role involves checking everything from high-speed signalling to the level of dust in a customer facility, as a single rack can contain half a million components. She describes the process as 'the Avengers assembling', where engineers from different disciplines race to make a system work. Her work ensures that the complex hardware required to run AI can be trusted in real-world conditions.

The engineer says validation is about being the 'first customers' for a product, exercising it to its limits before mass production. She notes that the pressure of the work is inseparable from the pleasure of it, as each failure mode offers a chance to make the next system better. Fiza says she is excited about the products in the pipeline, which she believes will 'change the world.'
