• Contribute to the methodologies and workflows of our growing European hub, collaborating with global teams to maintain a "best-in-class" testing standard.

• 3+ years of hands-on experience specifically in Web Application and API Penetration Testing.
• A strong understanding of common attack methodologies, exploitation techniques, and the OWASP Top 10.
• Proficiency with networking protocols (TCP/HTTP) and a solid grasp of client-side and server-side languages.
• Practical expertise with Burp Suite, Caido, and other industry-standard security testing utilities.
