Balyasny Asset Management, the multi-strategy hedge fund based in Chicago, has been doing some significant quantitative and technology hiring in London. The fund, which recently ranked 23rd in Fortune's best small and medium finance workplaces list, has been busy recruiting both senior and junior staff from rivals. Dan Azzopardi joined this month as a managing director and head of macro technology from Rokos Capital Management, where he spent nearly three and a half years as CTO after nearly 11 years in markets technology at Barclays. Azzopardi will presumably be managing Balyasny's macro tech stack.
