Employee Testimonials

Steve H.

"The biggest misconception about Tech at Liberty Mutual is that the technology shop here is outdated, boring and lacks opportunity. There is a strong push for failing fast, going agile, building microservices, using the latest technology tools and building a culture of innovation."

Matt W.

"I like working at Liberty Mutual because they treat their employees very well. Liberty understands the importance of a work-life balance. Because I have significant vacation time, and a flexible workplace schedule, I come to work happier every day. I don't feel the pressure that I may be fired if I need to take a few days off or can't make it into the office due an appointment."

Matt K.
