Software Development Sydney, NSW 10,001+ employees Founded 2002 Public Company

Atlassian operates a mature, multi-product suite (Jira, Confluence, Trello, Loom) serving 300,000+ companies across enterprise and mid-market. The tech stack reveals a company migrating infrastructure layers: adopting Kubernetes, Strimzi, Istio, and Linkerd while phasing out Data Center—a shift toward containerized, cloud-native operations. Hiring velocity is decelerating despite 578 open roles, with engineering (193 roles) and sales (119) dominating the funnel, alongside elevated activity in data (24) and security (23)—pointing to ongoing cloud-transition investment and AI integration work.
