Responsibilities
Wait, I don't have Java experience and you still want to interview me? That's right! At Atlassian, we hire engineers that can demonstrate their ability to learn and keep up with new and emerging technologies. It's true that Atlassian's stack is primarily written in Java and in the role you'll be coding primarily in Java, but we do believe in using the right tools for the job rather than being tied to the tool (e.g. Java). We happen to have a variety of languages within our stack including Kotlin, Golang, Python, and Ruby. For the interview process, we want to see you at your best. This means that during the interview, we want you to code in whatever language you feel you're best at. This will give us a sense of your capabilities as a developer, which is all we need to make an accurate assessment for this role.
In this role, you'll get the chance to:
Drive large, complex projects autonomously, from technical design to launch
Determine plans-of-attack on large projects
Tackle complex architecture challenges, apply architectural standards and start using them on new projects
Lead code reviews & documentation as well as take on complex bug fixes, especially on high-risk problems
Be an example for thorough, meaningful code reviews
Partner across engineering teams to tackle company-wide initiatives spanning multiple projects
Transfer your depth of knowledge from your current language to excel as a Java developer.
Mentor more junior members
Qualifications
Sound like an exciting opportunity? We think so too... In order to set you up for impact on day one, we'll expect you to have this on your first day:
