• Interface with application vendors, application owners, and other departments as needed.

• Assess and secure internet‑facing applications by identifying exposed access points and prioritizing remediation of high‑risk entry vectors.

• Enforce standardized security controls for authentication, authorization, credential and secret management, encryption, and secure communication patterns.

• Partner with application owners and vendors to eliminate insecure configurations, excessive access, credential misuse, and other security issues.

• Evaluate and secure applications throughout their lifecycle including procurement, implementation, integration, and ongoing operations.

• Support third‑party risk management by assessing vendor integrations, data flow methods, and exposure points.

• Drive remediation of application vulnerabilities identified through vulnerability scanning (e.g., Qualys), configuration reviews, and security testing of externally facing systems.

• Improve visibility and governance over application security posture by tracking exposure trends, risk reduction, and remediation progress.

Knowledge, Skills and Abilities:

• Strong understanding of application‑layer attack paths including credential compromise, integration abuse, API exploitation, and external exposure risks.

• Deep knowledge of authentication and authorization models such as SSO, OAuth, service accounts, and secure integration patterns.

• Expertise in encryption and data protection across application and integration workflows.

• Experience in complex enterprise environments with large commercial application portfolios.

• Strong familiarity with OWASP Top 10, common exploitation techniques, IAM concepts, and secrets/credential lifecycle management.

• Knowledge of CIS Controls and Benchmarks as they apply to application security.

• Experience with vulnerability scanning and testing tools such as Qualys, Qualys WAS, Metasploit, SAST/DAST, and configuration/exposure analysis tools.

• Understanding of network and edge security including WAFs, firewalls, segmentation, and internet‑facing exposure.

• Ability to drive cross‑functional remediation across technical and non‑technical stakeholders.

• Strong analytical and prioritization skills in a risk‑based environment.

• Excellent communication skills with the ability to translate technical risk into business impact.
