Pros
It's a company with an industry competitive remuneration (salary + bonus + shares), with great facilities, and great food!. But any top tier company provides those these days. What I love most about Atlassian is their culture. From day one they make sure that you feel included in the company, I always felt that I have a say in what's going on, and I as an employee is kept up to date on all the company decisions. These feels great and really makes us feel that we are the true owners of the company. Also it's a place with friendly people and when recruiting new Atlassians they place extra attention to make sure that new hires fit the company culture.
Kontras
Not enough remote working. It would be great if it was possible to work remotely since many of the employees have relocated to work with Atlassian.
