HYDERABAD: E-commerce behemoth Amazon opened its largest campus building in the world in Hyderabad’s financial district on Wednesday at a time when it is taking on Walmart-owned Flipkart for supremacy in the Indian market.The campus is spread over 9.5 acres with a built-up space of 3 million square feet that can house 15,000 people. This the US giant’s first owned office building outside the US and has the capacity to house three times the number of people that its largest building in the US does.With this, Hyderabad will be home to not only a third of Amazon’s 62,000-plus headcount in India but also its largest employee base outside the US and the largest tech base outside Seattle.“This facility is the largest office building in Amazon’s global portfolio. With the addition of this building in Hyderabad, we will have 4 million square feet of office space across 8 buildings in the city,” said John Schoettler, Amazon’s vice-president of global real estate and facilities.Amit Agarwal, senior vice president and country manager, Amazon India, said the building would house the company’s tech manpower, including software development engineers and machine learning scientists, along with product managers, finance and other functions. “We have already migrated around 4,500 employees to the new campus and will be migrating more people from our other leased facilities,” Agarwal said.While Amazon officials refused to divulge investment figures for the new campus, they termed it as a reaffirmation of India’s importance in Amazon’s scheme of things in terms of market and talent.Agarwal said the company has already invested $5 billion in India and has committed another $500 million in food retail. The company was looking at hiring more people as it was planning for organic growth. He added that Amazon was also looking at stepping up exports from India to $5 billion over the next couple of years, which crossed $1 billion within two years of launch.Shrugging off any impact of a global slowdown on its India business, Agarwal said the Jeff Bezos-led company continues to invest across all its businesses with focus on improving affordability.“We haven’t seen any slowdown yet. One reason could be that e-commerce is a very small portion of retail, probably just 3% of retail consumption. When it is that small there is so much room to grow,” he said.Amazon, which started its operations in India in 2004 with Hyderabad, has also made the city home to its largest fulfilment centre in the country at 4 lakh sq ft, which is set to grow to 5.8 lakh sq ft by mid-2020.
