Salaries for technology professionals rose 2% in 2014 to $89,450 on average annually, according to a salary survey released today by job board operator Dice Holdings Inc. Additionally, 37% of tech pros cited receiving a bonus in 2014, up slightly from 34% in 2013. The average bonus in 2014 rose 2% year over year to $9,538.

More than half, 61%, of technology professionals earned higher salaries in 2014, most frequently citing a merit raise as the reason for the increase. Another 25 percent say they received higher wages due to changing employers within the year.

The Pacific region as a whole saw the highest bump in salaries and tech professionals in Silicon Valley are again the highest paid in the country, earning $112,610 on average, up 4% year over year.

Big data and cloud dominate the skills which earn the highest paychecks in 2014:

“As demand for technology professionals rises and highly-skilled talent is harder to find, the pressure is being reflected where it counts: paychecks,” said Shravan Goli, president of Dice.com. “Still, tech pros are less happy with their earnings, signaling to companies that in order to recruit and retain the best candidates, offering more will be necessary.”

The Dice salary survey was administered online with 23,470 employed technology professionals responding between Sept. 29 and Nov. 17, 2014.
