The Role:
Citi is seeking an Application Security Penetration Tester to join its Offensive Security team, conducting deep-dive vulnerability assessments across web applications, mobile, thick clients, APIs, microservices, and emerging Generative AI/LLM implementations. This role is well-suited for either an experienced penetration tester looking to deepen their offensive security career or a software developer/engineer seeking to transition into cybersecurity. The analyst will manually identify, research, validate, and safely exploit known and zero-day vulnerabilities, then translate technical findings into clear risk guidance for developers, architects, and ML engineers. A key focus of the role is researching and applying LLM-based security testing techniques to uncover complex, non-obvious vulnerabilities that evade traditional automated and manual testing. The team supports pentesting of the firm's most critical applications while actively researching AI/LLM-driven automation to enhance pentest effectiveness.
