Julien Merceron is the new worldwide technology director for Konami Digital Entertainment, and will start work at the new European headquarters on October 1.
"Julien brings with him an incredible awareness of how to take games as an entertainment force forward," said Konami's European president, Shinji Hirano.
"He will be a key member of our talented development community and be integral to ensuring that future titles will push the limits of what can be technically achieved, while ensuring they retain Konami's famed gameplay. We welcome him and his talents to the team."
His duties will involve work on future iterations of Kojima Productions' FOX Engine.
Merceron makes the move from Square Enix, where he was also worldwide technology director. He joined the company in April 2009 as CTO, after more than three years with Eidos. He's also worked with Ubisoft as both a programmer and as worldwide technology director, and can be found on the BAFTA jury and GDC advisory board.
