Job description
Why RingCentral? A Global Market leader in Cloud Telephony with strong presence in overall Unified Communications (Telephony, Video conferencing and Messaging) space is enthusiastically setting up their office in India. This is an opportunity to innovate at scale and create a meaningful impact on billions of lives. We are just laying the foundation of 2 of the largest innovation hubs for RingCentral (Bangalore and Gurgaon to start with) in the world. You have an opportunity to be a founding member and shape the future. https://www.ringcentral.com/us/en/blog/employees-know-best-ringcentral-ranks-18-on-glassdoors-2021-best-places-to-work-list/ Exclusive partnership with Avaya, Alcatel-Lucent and Atos gives exclusive access to ~200M enterprise phone customers who will likely move to cloud phones over the coming years, setting path for rapid growth for RingCentral. Every employee is a stakeholder in the company and the rapid growth trajectory provides a good wealth creation opportunity. Hyper Scale Problems: Communication technology by its nature has the largest scale of any businesses out there - much larger than social media, e-commerce or anything else. An extremely large scale, very low latency needs and a very high uptime (99.999% or better) need provides an opportunity to solve very complex problems and push the boundaries. A publicly traded sizeable company with a long track record provides a good stable environment while still being growth focussed. Hustle of a 0-1 journey of entering a new country; rigor of one of the largest scales in the world and of a publicly traded company provides the best of both worlds. Pure play software company: Only thing we build and sell is software: Cloud Telephony, Video and Audio conferencing, Messaging and Cloud Contact Center. As a software builder, you own the business. Great employees and customers centric culture. https://www.comparably.com/blog/best-engineering-teams-2021/ https://www.comparably.com/companies/ringcentral/employer-brand https://www.businesswire.com/news/home/20200427005117/en/RingCentral-Recognized-by-San-Francisco-Business-Times-and-Silicon-Valley-Business-Journal-as-Best-Place-to-Work-San-Francisco-Bay-Area https://www.ringcentral.com/us/en/blog/ringcentral-manila-named-asias-best-company-to-work-for/ Led by a well-known, innovative and seasoned technology leader in India: https://www.linkedin.com/in/anilgoel1/?originalSubdomain=in Skills : Java developer - Must have experience in developing and designing apis Experience : 5 to 9 years Interested candidates please send your CVs to prassana.kumar@ringcentral.com
