Driss Ben-Brahmin will take on a partner position at the hedge fund company and will develop and head up a special situations platform â which will include the firm's existing $12 billion emerging markets department.
The former trader will also develop a global macro platform and a number of options designed to cater for sovereign wealth funds.
Manny Roman, joint chief executive of GLG, said: "Driss brings to GLG a unique combination of technical, investment and cross-asset class trading experience.
"His successful experience in developing an Emerging Markets trading and principal investment business for Goldman Sachs gives him a unique perspective on both global macro-economic themes and special opportunities."
Fellow chief executive Noam Gottesman, added: "Our New Markets franchise, including the Middle East, will be a clear beneficiary of his appointment, and he will be a key driver of GLG's new strategic development efforts."
