• Define secure coding standards and security requirements for different application types based on data classification and risk profile
• Architect security solutions for authentication, authorization, encryption, and secure communication channels
• Establish security guardrails for cloud-native applications, serverless architectures, and infrastructure-as-code implementations
• Design and implement API security strategies including OAuth/OIDC flows, API gateways, and rate limiting
• Integrate security architecture principles into CI/CD pipelines to support DevSecOps initiatives
• Evaluate and recommend security tools and technologies for the enterprise security tech stack
• Develop security architecture roadmaps and guide implementation of security capabilities
• Partner with development teams to design secure solutions that balance security requirements with business needs
• Lead strategic security initiatives with enterprise-wide impact
• Leverage GenAI technologies to enhance security architecture reviews and automate security analysis
• Maintain documentation of security architecture decisions, patterns, and reference implementations
• Develop and deliver security architecture training to raise security awareness among developers and architects

• Deep knowledge of secure design principles, threat modeling methodologies, and security patterns
• Experience designing security controls for cloud environments (AWS, Azure, Google Cloud Platform)
• Proficiency in evaluating and implementing application security tools (SAST, DAST, IAST, SCA)
• Hands-on experience with security testing tools such as Burp Suite, OWASP ZAP, and other proxy tools
• Experience with secure software development practices and DevSecOps implementation
• Strong understanding of OWASP Top 10, SANS CWE, and other security standards
• Knowledge of secure authentication mechanisms (MFA, SSO, OAuth 2.0, SAML, OIDC)
• Experience with secure API design and implementation of API security controls
• Knowledge of regulatory requirements (PCI-DSS, GDPR, SOX, etc.) and their architectural implications
• Experience with containerization, microservices, and API security
• Proficiency in one or more programming languages (Java, Python, JavaScript preferred)
• Experience with secure code review techniques and identifying common vulnerability patterns
• Knowledge of cryptographic protocols and implementations
• Experience with security requirements for modern application architectures (SPA, serverless, etc.)
• Excellent communication skills with ability to translate complex security concepts to technical and non-technical audiences
• Experience leading cross-functional security initiatives and influencing stakeholders
• Certifications such as CSSLP, CISSP, AWS Security Specialty are highly desirable

This position requires a strategic thinker who can balance security requirements with business objectives while driving the organization toward a more secure application ecosystem.
