This role is responsible for advancing secure development practices, integrating security into the software development lifecycle, and partnering with engineering teams to reduce application risk through scalable security solutions. The ideal candidate combines deep technical expertise with strategic thinking, enables developers, scales security through automation, and influences engineering organizations without direct authority.

• Provide technical leadership across Secure Software Development Lifecycle (SSDLC), Static Application Security Testing (SAST), Dynamic Application Security Testing (DAST), Software Composition Analysis (SCA), Threat Modeling, and Penetration Testing.
• Guide engineering teams in vulnerability remediation and secure coding best practices.
• Evaluate emerging application security technologies, emerging risks, and recommend pragmatic, risk-based improvements to application security capabilities.
• Partner with Security Architecture to ensure application security practices align with enterprise security standards and design principles.

• Design and build automation that integrates security seamlessly into CI/CD pipelines.
• Develop tooling, APIs, and automation to improve developer experience and reduce manual effort.
• Partner with platform engineering teams to implement security controls within modern development workflows.
• Identify and implement opportunities to leverage AI and generative AI technologies to improve application security processes, automate repetitive tasks, enhance developer enablement, and accelerate vulnerability detection and remediation while ensuring responsible and secure use of AI.

• Champion developer enablement by creating security guidance, reusable frameworks, documentation, and training.
• Establish and track metrics that measure program effectiveness and continuously improve security maturity.

• Mentor engineers and promote security best practices across the organization.

• Solve complex application security challenges involving modern software architectures and cloud-native platforms.
• Drive continuous improvement across security tooling, developer workflows, and vulnerability management processes.
