Boston Fire Commissioner Roderick Fraser Jr., who has presided over a fractious fire force over the past seven years, is resigning his post, effective Jan. 6, to seek work in the private sector.
Fraser, 49, submitted his resignation to Mayor Thomas M. Menino Monday, ending his career at the oldest professional fire force in the nation and leaving open two permanent high-level positions on the Boston Fire Department, including a permanent fire chief.
“As I look back on my years here, I’m leaving a much better department than when I found it,” said Fraser. “And I’m proud of that. I felt it was time for me to move on and do something different.”
Fraser said he was not forced out and is leaving on his own terms, adding that he is “looking for new challenges in the private sector.” Full story for BostonGlobe.com subscribers.
