Job Description

Overview

The Global Application Security & DevSecOps Lead is responsible for, operating and continuously improving the organisation’s application security function across the complete software development lifecycle.

The role owns the policies, technical standards, engineering controls, security testing services, Azure DevOps integrations, application security platforms and governance processes required to ensure that internally developed and externally supplied applications are designed, built, tested and released securely.

This is both a leadership and hands-on engineering role. The role holder must be capable of defining the global AppSec strategy while also configuring, integrating, operating, troubleshooting and improving the underlying security tools.

The role will embed automated and risk-based security controls into Azure DevOps repositories and CI/CD pipelines at enterprise scale, covering potentially hundreds of Azure DevOps projects and thousands of repositories.

The role is accountable for ensuring that security controls are:

• Technically effective.

• Integrated into engineering workflows.

• Proportionate to application risk.

• Reliable enough to support mandatory release gates.

• Properly tuned to minimise false positives.

• Measurable and auditable.

• Supported by clear operating procedures.

• Adopted consistently across global development teams.

Explicit scope boundary: not enterprise vulnerability management

This role does not own the central enterprise vulnerability management function.

The following remain outside the role unless separately assigned:

• Operating-system vulnerability scanning.

• General infrastructure vulnerability scanning.

• Network-device vulnerability management.

• Endpoint vulnerability management.

• Enterprise-wide CVE reporting unrelated to applications.

• Infrastructure penetration testing.

The AppSec function nevertheless owns the management of security defects, including:

• Validation and triage of AppSec findings.

• Removal of false positives and duplicate findings.

• Assignment of findings to the correct engineering teams.

• Definition of application-security remediation requirements.

• Verification that fixes are effective.

• Management of AppSec-specific exceptions.

• Reporting on application-security exposure.

• Escalation of overdue high-risk application findings.

For containers, the function owns build-time image and Dockerfile security. Runtime host, node and deployed-container vulnerability management should remain with Cloud Security, Platform Security or Vulnerability Management, subject to a defined RACI.
