Atlassian is a blend of humor and serious follow-through, evident in its guiding principles which include “Don’t #@!% the Customer” and “Open Company, No Bullshit.” That mentality extends to its employees, who work hard but don’t take themselves too seriously. They describe the company as friendly, direct and collaborative. Plus, Atlassian offers a slew of other perks, including a beer car on Fridays, a paid week to volunteer, a free daily lunch service and unlimited vacation with their manager’s approval. “The company values really matter at Atlassian,” said one employee. “Not only does management talk about the values, but staff at all levels of the organization discuss them and integrate them into their work.” Read the Great Place to Work review.
