Role Overview

As a Penetration Tester, you will perform hands-on technical security testing across a range of environments and technologies, working on complex and high-value projects.

Review system architecture and application designs for security weaknesses.

Stay current with the latest attack techniques, vulnerabilities, and tools.
Participate in internal knowledge sharing, tool development, and security research.
Support sales activities with technical insights when needed (e.g., scoping calls, workshops).

Required Skills / Experience

Hands-on experience as a penetration tester, with a proven track record of delivering quality security assessments.
Industry experience working in Dev/Admin/Engineer field
Industry experience working in the Information security field as a penetration tester
Development and/or source code review experience in C/C++, C#, VB.NET, ASP, PHP, Java, Python or Ruby

Understanding of Security Auditing tools
