The CTO has worked in senior roles at Thomson Reuters - where he is credited for overseeing the design and development of the Refinitiv Eikon system - as well as Amazon and Citadel.

Luma Financial Technologies, a multi-issuer structured products and annuities platform, has named Arun Kumar as chief technology officer, reporting directly to Tim Bonacci, president and chief executive of Luma. He takes over from Adam Hutcheson, who left Luma in August.

Based in Luma’s New York City office, Kumar will oversee the development and dissemination of the firm’s technology.

Kumar is joining Luma from Citadel LLC, where he was responsible for core platforms, enterprise data and analytics, enabling faster time to market from idea generation to trading strategies and trade execution. Previously at Amazon, he led a team of more than 450 engineers, product managers, scientists and operation managers to aggressively build and maintain their machine learning platforms powering the entire Amazon.com website.

Arun also spent time as the global head of development at Thomson Reuters where he is credited for overseeing the design and development of Thomson Reuters’ (Refinitiv) $2 billion revenue-generating premium Market Data platform - Eikon.
