Samsung's current chief technology officer for the mobile division, Rhee In-jong, has officially parted ways with the company, saying that he felt he could not fulfill his fatherly duties to his daughter while in his current employment. Rhee sent out an email to Samsung staff saying that his daughter had recently been deployed to Iraq as a member of the United States Armed Forces, and he needed to leave his role at Samsung in order to be there for her as he felt he should. His resignation is effective immediately, and there is reportedly no fixed time frame for when he will return, if he will be coming back at all.
Rhee joined Samsung back in 2011, after spending some time teaching computer science at North Carolina State University. Before falling in with Samsung, Rhee devoted his time to research, and wound up developing BIC and CUBIC, two of the TCP congestion algorithms at the core of how Linux-based systems worldwide handle internet traffic. His passion for development carried him during his time at Samsung, seeing him helping to develop the Knox security suite and Samsung Pay. He eventually wound up as the lead developer for Bixby, the voice assistant that debuted alongside the Galaxy S8 flagship family.
The engineering position where he accomplished all of those feats was actually not In-jong's current when the big corporate shakeup within Samsung happened at the end of October; he was already the mobile division's chief technology officer at that point, among other roles. With executives reshuffled into different divisions and some leaving the company entirely, the fact that In-jong was kept where he was serves as a testament to his accomplishments and his fitness for that particular position. The news of his daughter's deployment was enough to shake In-jong out of his newly-earned role after serving for just over a month. Rhee has yet to make any announcements on the matter. His LinkedIn page still lists him as being employed with Samsung. Likewise, Samsung has yet to officially say anything on the matter, and has thus not yet named a successor for In-jong's multiple positions.
