Security Engineer (Pentesting, Incident Response & Investigations)

Join Talkdesk as a Security Engineer specializing in Pentesting, Incident Response, and Security Investigations. You will play a key role in detecting, investigating, and preventing security incidents while proactively identifying weaknesses across our platforms and applications. This role involves performing manual and automated penetration testing of web applications, APIs, cloud-based systems, and AI/ML models, conducting security assessments focusing on emerging threats like prompt injection and adversarial attacks, and leading incident response efforts including detection, containment, and eradication.

Your responsibilities will include analyzing logs and forensic artifacts to support investigations, triaging and validating findings from penetration tests, working with engineering teams to explain vulnerabilities and verify fixes, performing threat modeling using methodologies like STRIDE, and continuously researching emerging threats and attack techniques. You will act as a security subject-matter expert during incidents and high-risk technical discussions, helping improve Talkdesk's overall security posture through proactive testing and lessons learned. This position requires strong application and systems security knowledge, practical penetration testing experience, understanding of OWASP Top 10 and AI exploitation patterns, and excellent communication skills.
