Rajagopalan was employed with Infosys from August'14. He headed the Design Thinking department that oversaw the creation and implementation of a user-centred approach to problem-solving.
His resignation was widely speculated though: earlier, former chairman R Seshasayee and co-chairman Ravi Venkatesan also quit amid the Sikka-Narayana Murthy battle.
However, Infosys refused to comment on "exits or appointments other than those of key management personnel".
Despite turbulence, Infosys isn't compromising on recruitment
Despite Sikka's resignation and turbulence over clashes between board members and founders over corporate governance issues, Infosys has announced that it will continue to recruit 6,000 employees per annum for the next two years.
The IT-giant has also stepped up recruiting drives in the US and European markets, as it looks to tap opportunities there and tide over visa-related issues.
