Based in London, Gladkow will become the “ETF ambassador” in Europe for the securities arm of the Korean Asset Manager, according to his LinkedIn profile.
He will be responsible for enhancing the strategic direction of the firm as a trusted partner in the European ETF space.
Gladkow, who joined Mirae in August, spent almost nine years at Tradeweb, most recently based in New York for five years as the director of rates sales.
Prior to this, he was vice president for ETF and equity derivative sales at the firm in London where he spent over three years.
He started his career at Morgan Stanley in 2007 as a trader assistant on the ETF desk before becoming an equity sales specialist at the business in 2011.
Williams joined having spent 18 months at Lyxor before Amundi acquired its French rival.
In June, Mirae Asset Global Investments and Global X acquired ETF Securities Australia which houses roughly A$4.7bn assets under management (AUM).
Mirae is currently represented in the European ETF market by Global X, which it acquired in 2018, with the firm embarking on a rapid expansion of its European ETF range this year.
