The development comes amid an organisational restructuring that co-founder and chairman NR Narayana Murthy is overseeing after he returned to the company in June to revive its sagging fortunes.
In July, Basab Pradhan had announced his decision to resign as global sales head of Infosys. Shaji Farooq, who served as senior vice-president and head of financial services for the Americas and had been with Infosys for a decade, quit last year to join rival Wipro.
In the June quarter, the North American market contributed 61.4% of Infosys' revenue of Rs. 11,267 crore. Banking and financial services account for 27% of revenue.
Murthy has made new appointments in its executive council as a part of his turnaround plan. Earlier this week, Infosys named Ranganath D Mavinakere, Binod Hampapur Rangadore and Nithyanandan Radhakrishnan to the high-level body that frames business strategy.
