This is a Melbourne-based fractional engagement, ideally 2–3 days per week for an initial 2–3 months, with potential for a longer-term opportunity.

We work by design, not by default. A select client model means the work is deliberate, the relationships are real, and your impact is measurable.

Being AI-native is not a positioning line. It shapes how every person here delivers. You will have the tools to move fast and a team that builds with AI every day.

We are serious about people. A safe, supportive environment shapes how we work, grow and lead. Real ownership. Direct access to leadership. A team worth showing up for.

If this sounds like the kind of strategic challenge you’d enjoy, we’d love to hear from you. Tell us about a piece of work you’re proud of, the impact it had, and how you used AI to improve your thinking or execution. That is what matters most to us.

Overdose is an equal opportunity employer. We welcome applications from all backgrounds and are committed to a fair and inclusive recruitment process.
