Penetration Testers (Mid/Senior) | $140K-$180K | Consultancy

Save job

Our client is heavily investing into their offensive security practice this year, currently seeking two elite testers. Joining a premier consultancy, you'll be initially embedded in a Big 4 bank to break, model, and secure critical financial infrastructure. You’re a consultant owning the lifecycle from scoping to remediation across web, mobile, API, and cloud at scale. Lead advanced testing and mentor others in a high-stakes, modern environment

What you will actually do:

  • Plan and perform deep-dive penetration tests across web, mobile, API, cloud, and infrastructure environments using manual and automated techniques.
  • Threat Modeling & Analysis: Conduct attack surface analysis and threat modeling to identify complex business logic flaws that automated tools miss.
  • Act as the bridge between security and engineering by explaining findings and recommending specific, actionable remediation strategies to technical stakeholders.
  • Offensive Automation: Develop and maintain custom scripts (Python, PowerShell, Bash) to automate testing processes and improve exploit delivery.
  • Technical Mentorship (Senior): Guide and provide quality assurance for junior testers, ensuring the highest standard of technical output and report writing.

Key Requirements:

  • Hands-on Depth: 7+ years (Senior) or 3+ years (Mid) of dedicated experience in offensive penetration testing and vulnerability assessment.
  • Technical Arsenal: Mastery of OWASP, SANS, and NIST frameworks, with a deep understanding of CSRF, XXE, SQLi, and Deserialization vulnerabilities.
  • Strategic Reporting: Proven ability to produce detailed, risk-based reports that translate complex technical vulnerabilities into executive-level risk assessments.
  • Industry Validation: Relevant hands-on certifications are highly preferred, such as OSCP, OSCE, GPEN, GWAPT.
  • Communication Skills: Exceptional verbal and written skills to manage tough, collaborative conversations with developers and business owners.

Aboriginal and Torres Strait Islander Peoples are encouraged to apply.
