Cyber Security Specialist | AISA NSW Executive Committee | Helping Build Australia's Best Cyber Security Teams
Full-time role with competitive salary plus equity with real financial value!
Are you a Pen Tester, looking to be apart of something that is shaping the future of Penetration Testing and AI. You'll be the human behind the machine, validating and guiding AI-driven assessments.
About Company
We're working with a company that is redefining how penetration testing is done - combining AI automation with human expertise to deliver faster, smarter, and more reliable security testing. The platform simulates real-world attacker behaviour, automating repetitive tasks while expert testers validate and refine results for accuracy and actionable insight.
Backed by leading venture investors, we're building the next generation of AI-driven offensive security tools - empowering organisations to continuously test and strengthen their defences with speed, scale, and confidence.
The Role
We're looking for a Penetration Tester (4+ years experience) to join and become the human in the loop - the critical expert who keeps the machine honest.
In this role, you will:
* Validate and refine AI-generated test results - identify false positives, correct hallucinated findings, and ensure accuracy before reports go to clients.
* Perform hands‐on testing across web apps, APIs, and authentication layers - you'll have full autonomy to test and explore as you would in a real engagement.
* Collaborate with our AI engineering team - provide feedback on model behaviour, help improve the LLM's accuracy, and close gaps between human and machine understanding.
* Contribute to high‐quality pen testing reports - bringing consulting polish and precision to every client deliverable.
* Grow with us - You will be at the forefront of building the vision and the product, and grow with the business that's heading in a positive direction.
What we're looking for
* 4+ years of experience in penetration testing (web app, black box, API).
* OSCP certification (or similar industry certifications such as OSEP, CREST or GPEN).
* Strong consulting and communication skills - you can translate findings into actionable insights.
* Pragmatic, collaborative, and curious about AI, automation, and innovation in offensive security.
* Familiarity with industry frameworks (OWASP, ISO, SOC2, etc.).
Why This Role?
If you're tired of the same old pen test cycles and want to work on something more creative and impactful, this is your chance.
You'll have a direct hand in:
* Shaping how AI can augment and accelerate penetration testing.
* Partnering with engineers and security minds to train the next generation of security tools.
* Joining early in a venture that's already landed its first customers and is backed by top‐tier investors.
The Future Is Already Here
This isn't another PenTesting gig - it's a chance to be part of something new.
A bridge between human skill and AI capability.
A role that lets you keep your hands on the keyboard and your head in the future.
Join them early - or compete with them later.
