    • You dig deeper into every finding. Doesn't stop until impact is proven.
    • You are comfortable being uncomfortable. Goes towards obstacles, not away from them. Consulting isn't your typical job and requires adapting to rapidly changing environments.

    • You are Self-motivated and dependable.

    • We are looking for an experienced developer/application security tester to join our team:
      • Solid working knowledge of programming languages, including C, C#, Python, Objective-C, Java, JavaScript, SQL, and frameworks like AngularJS.
      • Familiarity with web services and data exchange formats such as XML, JSON, SOAP, REST, and AJAX.
      • Understanding of AI/LLM weaknesses and flaws in applications.
      • Extensive experience/expertise in using an attack proxy (e.g. Burp Suite)
    • Preferred if you have 3 - 5 years of experience working in penetration testing and consulting
    • A graduate of a post-secondary college or university degree program.
    • Has at least two years of experience dealing with information security-related tasks.
    • Has professional qualifications (one or more): OSCP, OSWE, BSCP. 
      • OSCP or Burp is mandatory for our organization.

What you’ll be doing

  • Your primary role is to perform penetration testing of web applications, mobile applications, thick clients, and APIs.
  • Source code review and whitebox penetration testing to prove the impact of application flaws.
  • Reverse engineering of mobile and thick client applications.
  • You sometimes chain application flaws to other areas, such as cloud and on-prem AD infrastructure. Opportunities for lateral movement into the infrastructure teams are limited and given at the manager's discretion.
  • Develop detailed reports on findings and remediations for impactful findings. You will learn to debrief these findings at both a technical and executive level.
  • Perform SAST and DAST on enterprise, SaaS, and custom in-house applications.
  • Experience in using scanners and knowledge of validation and elimination of false positives.

About the Company

Packetlabs was built by an ethical hacker after seeing vulnerability assessments presented as penetration tests. Our slogan "Ready for more than a VA scan?" drives at the importance of not providing our clients with a false sense of security.

 
We are a passionate team of highly trained, proactive, pentesters. We provide expert-level penetration testing services that are thorough and tailored to help foster a safe digital space where everyone has the right to privacy and security. Packetlabs consultants find weaknesses others overlook and continuously learn new ways to evade controls. We hold ourselves to a very high standard.


To do so, we only hire individuals with the same drive and passion.

Note: While the position is based in Australia, initial onboarding and collaboration may involve some after-hours work to align with our Eastern Time Zone (Canada/US) team. Flexible scheduling options will be supported as the role transitions to standard local hours.
