Axiom is expanding its Centre of Excellence in the city by opening a new 3,000 square foot office.
Enterprise Minister Arlene Foster said the announcement reaffirmed Axiom's decision to choose Northern Ireland over other locations.
"These are high quality positions with salaries well above the Northern Ireland private sector median, contributing almost £4million a year to the local economy.
"Axiom's continued commitment to Northern Ireland through its plans for further hiring and office growth into 2013 reinforces the message that Belfast is a good place to do business. Invest Northern Ireland will continue to work with Axiom to support it in its plans," she added.
Employment and Learning Minister Stephen Farry added: "I welcome this news, which reinforces that Northern Ireland has graduates with the skills needed by potential investors. Through the Assured Skills programme, my Department has also engaged directly with Axiom over the last year.
"This will shortly result in the delivery of bespoke training developed in conjunction with the higher education sector."
