• Produce high-quality technical reports and present findings to both technical and non-technical stakeholders.
• Work closely with IT, Cyber Security, and business teams to prioritise remediation efforts and enhance security controls.
• Partner with defensive security teams to strengthen detection and response capabilities through shared knowledge and attack simulation activities.
• Support the development of security standards, policies, and hardening practices informed by offensive security insights.

• The ability to develop custom scripts and automation using languages such as Python, Java, C#, or C++.
