Principal Penetration Tester

We're looking for a senior or principal level offensive security professional to lead engagements - someone with the depth of a researcher and the judgment of someone who's done this long enough to know where scanners stop being useful.

About the Company

A highly technical Australian team doing adversarial work with enterprise clients in Australia and globally. Diverse engagements, genuine technical autonomy, and competitive compensation. They value how you think, not just what you've tested.

About You

You're an analytical problem-solver with a natural curiosity for how systems really break. You think in attack paths, chain weaknesses together, and ask "what would an attacker actually do next?" You're comfortable setting that standard for others, not just following it.

Ideally based in Sydney - but for the right level of seniority and expertise, remote within Australia may be considered.

What You'll Do
Lead offensive security engagements end-to-end
Think beyond single vulnerabilities to full attack chains




Set technical standards and mentor others
Build tooling to sharpen how engagements are run
Be a trusted technical voice for clients

What You'll Need
A strong offensive security background, with demonstrated experience
Solid technical fundamentals and the ability to build your own tools
Robust communication skills across technical and non-technical audiences

Titles and certifications matter less here - it's how you think and how you approach problems.

Why Join?
Real influence over methodology and tooling, not just execution
Varied, meaningful work with no cookie-cutter testing
A highly technical, collaborative team
Hybrid flexibility, meal allowances, fun team activities
Above-market compensation and strong advantages

Additional information
Permanent role
Sydney Based
Up to $200K + Super (dependent on experience)
