Responsibilities

Lead or support application security assessments for internally developed, third-party, SaaS, cloud-hosted, web, mobile, and API-based applications.
Perform secure code reviews and provide actionable remediation guidance for common application security issues, including authentication, authorization, input validation, secrets exposure, insecure dependencies, API abuse, logging gaps, and insecure configuration.
Partner with development teams to implement secure coding practices throughout the SDLC, including threat modeling, design reviews, peer review standards, and release readiness checks.
Operate and improve application security tooling such as SAST, DAST, SCA, container scanning, IaC scanning, secrets detection, API security tools, and CI/CD security controls.
Review application architecture, data flows, cloud deployment patterns, and integration designs to identify security risks before production deployment.
Translate vulnerability findings into prioritized, risk-based remediation plans and work with application owners, developers, DevOps, and product teams to drive closure.
Secure application-side configurations, including encryption, session management, authentication flows, authorization models, logging, error handling, secure headers, CORS, API gateways, and secrets management.
Support cloud security control design and validation across platforms such as Azure, AWS, or GCP, including IAM, network segmentation, workload protection, logging, storage security, key management, and policy-as-code.
Advise on DevSecOps practices, including secure CI/CD pipelines, branch protection, dependency governance, artifact signing, container hardening, and environment separation.
Coordinate with security operations teams on application-related incidents, suspicious activity, exploit attempts, and remediation validation.
Support vulnerability management by validating exploitability, reducing false positives, documenting compensating controls, and tracking remediation evidence.
Develop and maintain application security standards, secure coding guidelines, design patterns, checklists, procedures, and technical documentation.
Support audit and compliance activities by providing evidence for secure development, change management, access controls, logging, vulnerability remediation, and cloud security controls.
Mentor developers, security analysts, and IT teams on application security concepts and practical remediation techniques.
