Penetration Tester

This position can be based in Brisbane, Melbourne or Sydney.

We're not your typical cyber team
. We're collaborative, curious, and customer-obsessed and we're on the hunt for a sharp, curious, and hands-on Penetration Tester to join our growing Cyber Security team. If you love diving deep into systems, thinking like an attacker, and helping organisations stay one step ahead, this role is for you.

What You'll Be Doing

You'll be at the frontline of offensive security, uncovering vulnerabilities across networks, applications, and infrastructure, and working alongside our Cyber Consulting and Managed Services teams to turn findings into actionable solutions. This is the perfect opportunity for someone who thrives on variety, relishes complex challenges, and is passionate about making a real impact in the security space.

• Conducting penetration testing across web, mobile, thick client, and wireless environments
• Performing Red Teaming, code reviews, and vulnerability assessments
• Embedding security assurance practices into client projects and operational environments
• Identifying, communicating, and advising on security issues and remediation strategies
• Improving tools, techniques, and methodologies for efficient testing outcomes
• Delivering clear, actionable reports for technical and non-technical stakeholders
• Supporting client engagements with on-site work as required

What You'll Bring

We're looking for a Penetration Tester with 2–4 years of experience and a strong foundation in offensive security. Your toolkit likely includes:

• Hands-on experience in penetration testing of web applications and internal networks (e.g., Active Directory)
• Familiarity with common tools (Burp Suite, Nmap, Metasploit, etc.)
• Scripting skills in Python, PowerShell or Bash
• Understanding of common vulnerabilities and security testing methodologies (e.g., OWASP Top 10)
• Strong written and verbal communication skills

Bonus Points

• Exposure to Red Teaming, mobile or wireless testing, or thick client assessments
• Background in system administration, networking or web development
• Experience with CTFs, bug bounty programs, or open-source security contributions
• OSCP, CREST CRT or other relevant certifications

We're a fast-moving and collaborative team, so we value curiosity, autonomy, and a practical, solutions-focused mindset. If you're eager to grow, love solving tough problems, and want to make a real impact in security, we'd love to hear from you. Even if you don't tick every box, don't let that hold you back.

At Orro, we're proud to support our people and the people who matter most to them in meaningful and inclusive ways.
