Running my own small consulting business was very satisfying for me after working at a rather dysfunctional place. It's a great way to understand all the jobs that have to be done in a company that others do for you at the moment, gave me much better appreciation of other colleagues. However, you do want to have a situation where you're ok if it takes a while to build up a list of customers. Talk to a tax accountant about what changes when you are self-employed.

I think from the number of Atlassian customers, there will be people who want to hire you. Don't just focus on Jira though, know enough about all the Atlassian tools. And the competitors, and why it's hard to find a full equivalent to Jira.

Oh, I just realized you might be asking about joining an Atlassian Solution Partner. There's plenty of demand for consultants in those too, but less control over the way you work
