Job Description/ Responsibilities
The role focuses on embedding security testing, vulnerability management, and business logic validation directly into CI/CD pipelines and post-deployment processes, ensuring comprehensive security coverage without impacting engineering velocity.
The ideal candidate will combine expertise in secure SDLC, automated security testing, DevSecOps, cloud-native applications, APIs, and manual penetration testing to improve application security posture across web, mobile, and microservices architectures. This aligns with Secure SDLC requirements, including SAST, DAST, SCA, and manual validation activities integrated throughout the development lifecycle.
