Application & Cloud Security Specialist (DAST Specialist)

Location: 4910 Tiedeman Road, Brooklyn Ohio Position Summary Our Cyber Application & Cloud Defense team operates within Key’s broader Cyber Defense function in Corporate Information Security. Our mission is to enable secure software delivery and resilient cloud environments by proactively identifying, assessing, and reducing application and cloud security risks.   The Application & Cloud Security Specialist is responsible for configuring and optimizing automated dynamic testing tools for API scanning and Dynamic Application Security Testing (DAST). The role will implement and configure DAST and API scans within CI/CD pipelines and on a schedule.   Qualified candidates will also be able to perform application security assessments and cloud security reviews across modern development and cloud-native environments. This role combines hands-on manual penetration testing with the use of SAST, SCA, and DAST tools, as well as cloud security posture evaluation through CSPM capabilities.   You will work closely with development, DevOps, and cloud engineering teams to integrate security into CI/CD pipelines and improve secure coding practices. This role requires strong technical depth, development experience, and proficiency with command-line tools.   The ideal candidate is hands-on, execution-focused, and comfortable leveraging modern tooling—including AI-powered development and security assistants—to improve productivity, testing depth, and vulnerability detection.

Implement automated dynamic application security testing tools across web applications, APIs, and distributed systems. Validate and tune API and DAST scan configurations, ensuring sufficient coverage and improving signal-to-noise ratio. Perform manual application security testing and penetration testing of web applications, APIs, and services. Review and validate findings from SAST, SCA, and DAST tools, including triage and false positive reduction. Conduct API security and dynamic testing to identify vulnerabilities and misconfigurations. Assess open-source dependencies and third-party libraries for vulnerabilities and supply chain risk. Evaluate cloud environments (GCP, Azure, AWS) for misconfigurations, excessive permissions, and exposure risks in support of the CSPM program. Implement and maintain CI/CD security integrations, including scanning tools and automation workflows. Develop scripts and CLI-based tooling to support scalable security testing and validation activities. Partner with development teams to remediate vulnerabilities and improve secure coding practices. Participate in architecture and design reviews, providing actionable security recommendations. Utilize AI tools and coding assistants to enhance productivity, automate analysis, and improve testing efficiency while maintaining secure and responsible usage practices. Track and report vulnerabilities, remediation progress, and security metrics.
