The successful candidate will have a strong R&D mindset, a natural curiosity, and a discipline to stay at the forefront of security and AI research, actively identifying new research opportunities. This role will collaborate closely with engineering, architecture, and risk teams to embed security intelligence across the firm's technology landscape.

Requirements

• 6+ years of experience in Cyber Security or related field.
• Master’s degree in computer science, Cyber Security or related field with a minimum of 3 years of experience in a penetration testing or application development role OR Bachelor’s degree in computer science, Cyber Security or related field with a minimum of 5 years of experience in a penetration testing or application development role
• Hands-on experience with security & Software engineering tooling : Burp Suite, SAST/DAST scanners, Claude Code, GH copilot & custom exploit development from CVE advisories
• Demonstrated proficiency in penetration testing across web, network, and binary domains
• Strong R&D mindset — demonstrated ability to independently identify new research opportunities, follow emerging academic and industry security research, and translate findings into actionable tooling or defensive improvements
• Good proficiency in reading, understanding, and working with code and its features — including the ability to navigate unfamiliar codebases, reason about code behaviour, identify logic flaws, and leverage language-specific constructs in security analysis and tool development
