AI Penetration Tester (AI Security)


About the Role

What if your penetration testing skills could directly shape how safe and secure AI systems are for millions of users worldwide? We're looking for experienced AI Penetration Testers to probe, attack, and stress-test AI-powered applications and infrastructure—finding and documenting vulnerabilities before they can be exploited.

This is a fully remote, flexible contract role, where your offensive security expertise meets the cutting edge of artificial intelligence. You’ll work on high-impact projects that directly improve the security posture of AI systems used at scale.

  • Location: Remote
  • Commitment: 10–40 hours/week

Responsibilities

  • Conduct penetration tests against:
    • AI-powered applications,
    • APIs, and
    • infrastructure, to uncover security vulnerabilities
  • Identify and exploit weaknesses in:
    • AI/ML pipelines (including prompt injection, model manipulation, data poisoning vectors, and authentication flaws)
  • Perform:
    • web application,
    • network, and
    • API security assessments using industry-standard tools and methodologies
  • Simulate real-world attack scenarios, from reconnaissance through exploitation and post-exploitation
  • Document findings in clear, structured reports, including:
    • Severity ratings,
    • Evidence, and
    • Actionable remediation guidance
  • Evaluate AI-specific attack surfaces, including:
    • Adversarial inputs,
    • Jailbreaks, and
    • Data exfiltration risks
  • Stay current with emerging AI security threats and contribute insights to improve testing methodologies
  • Work independently on task-based engagements on your own schedule

Reasons to use Rodeo

I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?

Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.

Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.

Start with a chat, not a search bar

Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
