IRONDEQUOIT, N.Y. -- A celebration Thursday for a business that now employs hundreds of people at what used to be a vacant shopping center.

A ceremonial ribbon cutting was held at Conduent Incorporated at Skyview on the Ridge, the former Medley Centre in Irondequoit.

Conduent is described by Empire State Development as the world's largest business process services company, assisting clients in healthcare, commercial, transportation and the public sector.  

Among Conduent's clients are the New York E-ZPass sytem and the state's Worker's Compensation board, in addition to domestic and international businesses that have a presence in New York State. 

The locally-based customer experience call center opened late last year.

Conduent employs more than 600 workers at the Irondequoit location. The company says it plans to hire an additional 350 people by the end of the year.
