Kumar was instrumental in the launch of Amazon India in 2013 and will succeed Manish Tiwary, effective October 1. He will also continue to oversee Amazon's consumer businesses in the Middle East, South Africa, and Turkey.
Tiwary stepped down last month after an eight-year tenure to explore opportunities outside the organization, as confirmed by Amazon, which did not provide further details.
This leadership change coincides with Amazon's aggressive expansion plans in India, where it aims to invest up to $26 billion by 2030, despite facing significant regulatory scrutiny.
Recently, Reuters reported that India's antitrust authority found Amazon and its main local competitor, Flipkart, in violation of laws for favoring certain sellers, prioritizing specific listings, and offering substantial discounts, which adversely affected other businesses.
The regulator may impose fines on these companies and require them to alter their business practices.
