Dean Bryen has joined the London Stock Exchange Group (LSEG), as head of cloud engineering. He says his team will be engineering cloud platforms and products across AWS, Azure and GCP for the exchange's internal engineering teams. 

Prior to joining LSEG, Bryen was CTO of cloud and DevSecOps platforms at UBS for two and a half years. In a farewell post on social media, he complimented its "talented team" on having the "highest standards."

Bryen spent eight years working in Big Tech, starting at AWS then moving to Microsoft. At AWS he was the EMEA lead technology evangelist for Alexa, while at Microsoft he was a director of cloud and security engineering.

Bryen is the most senior hire LSEG have made so far this year. It lost one of its cloud leaders, infrastructure program director Simon Bannister, to hedge fund Qube in May.
