That way, Atlassians have more control over supporting their family, personal goals, and other priorities. We can hire people in any country where we have a legal entity. Interviews and onboarding are conducted virtually, a part of being a distributed-first company.

For this role, our current base pay ranges for new hires in each zone are:

Zone A: $221,400 - $289,050

Zone B: $199,800 - $260,850
