Job description
The Application Security Engineer II plays a key role in strengthening application security across the software development lifecycle. This role sits within the Cyber Defense organization and is responsible for defining and documenting Secure SDLC requirements, developing and managing a hardened cloud container image repository, and embedding automated security testing into CI/CD pipelines.
The role requires hands-on technical capability combined with the ability to define standards, influence development teams, and ensure vulnerabilities are identified and remediated before final build and release, in alignment with agreed remediation timelines. The key responsibilities of this role are as described below:
Secure SDLC Requirements & Standards
- Define, document, and maintain Secure SDLC policies, standards, and procedures covering:
- Secure design and coding expectations
- Security testing requirements
- Build, release, and deployment security controls
- Partner with Engineering, Platform, and AppDev teams to ensure Secure SDLC requirements are:
- Practical and scalable
- Integrated into existing development workflows
- Clearly communicated and understood
- Utilizing the standardized Risk Operation processes, support governance activities, including reviews, exceptions, and continuous improvement of SDLC security requirements.
Container Security & Hardened Images
- Develop, manage, and maintain a hardened cloud container image repository for application workloads.
- Define baseline security requirements for container images, including:
- Base image selection and hardening
- Patch and dependency management
- Runtime security considerations
- Partner with platform and application teams to drive adoption of approved images and patterns.
- Ensure container images are scanned, updated, and versioned in alignment with security standards.
CI/CD Security Tooling & Integration
- Define and implement automated security testing within CI/CD pipelines, including:
- Static Application Security Testing (SAST)
- Dynamic Application Security Testing (DAST)
- Open-source and dependency vulnerability scanning
- Tune tools and rules to balance coverage, accuracy, and developer experience.
- Ensure security testing is integrated early in the pipeline to enable remediation prior to final build and deployment.
Vulnerability Management & Remediation
- Partner with engineering and application teams to ensure findings from SAST, DAST, and open-source scans are incorporated into the Risk Operation function and:
- Clearly triaged and prioritized
- Assigned appropriate ownership
- Remediated within agreed SLAs and timelines
- Track remediation progress and escalate systemic or repeated issues.
- Validate remediation and support secure release decisions.
Collaboration & Enablement
- Act as a trusted security partner to development and other relevant teams.
- Provide guidance on secure coding practices, vulnerability remediation, and threat patterns.
- Support application security reviews, threat modeling, and design discussions as needed.
- Contribute to continuous improvement of application security tooling, processes, and metrics., The team fosters a high-performance, collaborative environment centered around proactive technology risk management and excellent customer service. Members are expected to lead with accountability, communicate effectively across functions, and adapt to dynamic challenges. The culture values technical excellence, continuous improvement, and global coordination, ensuring technology risks are well managed.
