Responsibilities

Define and govern application security requirements, controls, and assurance activities embedded within that model
Partner with SCOE to ensure security is integrated without duplicating ownership of engineering platforms, tooling, or development standards
Partner with Engineering, the Software Center of Excellence (SCOE), and Cybersecurity leadership to reduce software supply chain risk, implement DevSecOps practices, and enforce secure development standards aligned to Zero Trust principles
Establish and lead an enterprise Application Security (AppSec) governance framework, including Secure SDLC and vulnerability management policies
Drive adoption and enforcement of secure coding standards, security testing requirements, and remediation SLAs across all application teams
Build a risk-based AppSec roadmap aligned to business criticality, “crown jewel” applications, and regulatory requirements
Serve as the central authority for secure software supply chain controls and application risk posture.
Design and implement a secure developer program addressing: Developer workstations vs business PCs, Removal of excessive local admin privileges, Elimination of unmanaged builds and compilers
Lead transformation to secure developer environments, including: Virtualized or hybrid development models, Centralized build infrastructure, Controlled developer access aligned with Zero Trust
Reduce risk associated with: Local code storage, Unvetted open-source dependencies, Developer endpoint compromise
Architect and implement a secure CI/CD pipeline with embedded controls: SAST, SCA, DAST integration, Secrets scanning, Artifact integrity and provenance validation, Pipeline enforcement (GitHub → CI → Artifact Repository → Test Environments)
Ensure no production artifacts bypass secure pipelines and all builds are traceable and verified.
Partner with SCOE to standardize DevSecOps tooling and pipeline templates enterprise-wide
Establish enterprise-wide application testing program, including: Static (SAST), Dynamic (DAST), and Software Composition Analysis (SCA), Manual and automated penetration testing for critical applications
Expand testing beyond web applications into embedded, ICS, and custom software platforms.
Build structured pen testing program for crown jewel applications, including third-party partnerships and remediation tracking.
Ensure security validation is embedded in CI/CD gates before production deployment .
Lead implementation of threat modeling capabilities for critical applications to identify design flaws early in SDLC.
Define and enforce secure-by-design principles across engineering teams.
Collaborate with architects and engineering to integrate Zero Trust architecture, segmentation, and secure design patterns.
Implement centralized tooling to: Aggregate SAST, SCA, DAST, and pen test findings, Provide a single pane of glass for application risk, Drive prioritization and remediation of vulnerabilities based on business risk and technical severity.
Establish KPIs such as: Mean time to remediate (MTTR), % of critical vulnerabilities fixed before release, Coverage of testing across applications
Build and lead a role-based application security training program for developers, architects, and QA
Provide: Secure coding guidance (language-specific), Secure development playbooks and reference architectures
Partner with SCOE to embed security practices into daily developer workflows and pipelines.
Expand the SCOE charter to include DevSecOps governance and enforcement.
Drive: Adoption of enterprise CI/CD standards, Secure pipeline templates, Standardized DevSecOps toolchain
Improve visibility and enforcement of security policies across all development teams.
