Cogna has appointed ex-Amazon AI leader Sam Ng as CTO.

Cogna uses AI to automate the IT consultancy process for critical infrastructure industries including utilities, construction, facilities management and logistics.

Ng brings nearly 20 years of engineering leadership experience at startups and public companies spanning Microsoft, Google, Amazon and more.

Most recently at Amazon, he led two major engineering programmes. In Amazon AI, his teams owned the language, compiler, framework, and tooling used to build training and inference workloads running on Amazon’s custom Trainium and Inferentia chips.

He also led a 300-person engineering organisation at Kindle, where he built two zero-to-one devices: Kindle Scribe, the first large-format Kindle with writing and notetaking, and Kindle Colorsoft, the first Kindle with a colour display.
