The outflow of key personnel is fueling concerns of technology leaks and dangerous brain drain.
Naver Corp., the country's dominant Internet portal and search engine, earlier announced that its chief technology officer (CTO), Song Chang-hyun, will leave the company.
Song, who served as the head of Naver Labs -- the research and development arm of the company -- tendered his resignation following CES 2019. Details of his next destination have not yet been released.
The engineer had been cited as the one who led Naver's latest achievements and other breakthroughs in artificial intelligence (AI) and robotic technologies.
Kim Jun-seok, the man behind the development of translation service Papago at Naver Labs, also moved to the AI-focused R&D center AIR Lab at the country's leading automaker Hyundai Motor Co.
The country's tech giant Samsung Electronics Co. has also witnessed a number of executives opting to work for rivals, which have been speeding up their hiring of qualified experts, mostly in the AI sector.
Rhee In-jong, who led the development of Bixby voice assistant technology, joined Google Inc. in February. He is to lead the U.S. technology giant's Internet of Things (IoT) business.
The expert, who also served as a chief technology officer of Samsung's mobile division, played a significant role in developing Samsung's Knox mobile security system and payment service Samsung Pay.
Tim Baxter, who led Samsung's American business, meanwhile, retired from his post as president and CEO earlier this year, with his absence expected to be felt going forward. (Yonhap)
