State Street was among six New England companies to be named to the list. "State Street is honored to receive this recognition for the second year in a row by a leading industry publication and, most importantly, by our own employees," said Joseph Antonellis, chief information officer for State Street. "This recognition as a best place to work for IT professionals can be attributed to our focus on technology and continual investment that keeps our customers and employees engaged at the leading-edge of development." Since 1994, Computerworld's annual "Best Places to Work in IT" feature has ranked the top 100 work environments for technology professionals, based on a comprehensive questionnaire regarding company offerings in categories such as benefits, diversity, career development, training and retention. In addition, this year Computerworld surveyed more than 20,400 IT workers for the list, and their responses factored heavily in determining the rankings. "This year's Best Places to Work rankings represent companies across the industry that recognize how a strong commitment to and investment in employees are synonymous with creating a great IT work environment," said Don Tennant, editor in chief of Computerworld. "Once again, we found that IT professionals are looking for rewarding and challenging projects, access to leading-edge technologies, career growth and development and a comfortable work/life balance. Our Best Places companies not only offer these benefits, but also do so in a manner that goes well above industry norms."
