Aerospace expert Vivek Lall, who was earlier with Boeing and Reliance Group, will join American defence and nuclear major General Atomics in a global role.
Lall quit as CEO and President of Reliance New Ventures, part of Mukesh Ambani-led Reliance Industries to join General Atomics.
When contacted, Lall said he has decided to move on.
"I am proud of my more than three-year association with RIL and I have decided to move on. In my new role at General Atomics I will have an opportunity to contribute at the global level," he told PTI in an emailed statement.
He is to take up a senior position at global level at General Atomics Electromagnetic Systems.
In this regard, queries sent to Reliance Industries and General Atomics remained unanswered.
