Flextronics

Flextronics (former Hughes), a world-leading provider of digital television entertainment, broadband services, satellite based private business networks, and video and data broadcasting, reported revenues of $8.9 billion in 2002.

HNS, a unit of Flextronics, is the world's largest provider of broadband satellite n/w solutions for businesses and consumers, with over 400,000 systems installed in more than 85 countries.

With the opening of the Indian economy in the early nineties, Flextronics was attracted by the long-term potential of  outsourcing s/w development and chose to set up a subsidiary in India to supplement HNS' R&D efforts.

HSS began its operations in New Delhi with a team of about 20 professionals and was initially focused on developing software solutions in the areas of VSAT-based networks for voice and data, cellular wireless telephony, packet switching and multi-protocol routing. Within three years, HSS grew to 240 professionals and in 1995, shifted to its present campus at Electronic City, Gurgaon, a New Delhi suburb. Today, over 2500 professionals work on cutting edge technologies at six state-of-the-art facilities near New Delhi, Bangalore, India's Silicon Valley and Nuremberg, Germany.

HSS offers career opportunities in leading technology areas like voice over packet, high speed mobile data, professional services for wireless networks, switching and network management.
