• Develop and maintain security architecture documentation, including data flows, trust models, security controls, and risk assessments.
• Define security guardrails, standards, and reference architectures for enterprise-wide adoption.

Threat Modeling & Risk Assessment

• Lead threat modeling exercises using methodologies such as STRIDE, PASTA, and ATT&CK-based approaches.
• Identify realistic attack paths and abuse scenarios across applications, cloud platforms, APIs, and AI systems.
• Translate security findings into actionable design and engineering recommendations.
• Drive risk-based decision-making aligned with business objectives.

Application Security & Secure SDLC

• Embed security throughout the Software Development Lifecycle (SDLC).
• Guide development teams on secure coding practices and security-by-design principles.
• Review application security findings from SAST, DAST, SCA, penetration testing, and code reviews.
• Drive remediation efforts and establish secure development standards.
• Support security requirements for APIs, mobile applications, web applications, and microservices.

Perimeter Defense & Security Controls

• Provide strategic oversight and tuning recommendations for:
  • Web Application Firewalls (WAF)
  • API Gateways
  • Bot Mitigation Platforms
  • DDoS Protection Services
  • CDN Security Controls
• Ensure effective protection against:
  • OWASP Top 10 threats
  • API attacks
  • Credential abuse
  • Automated bot attacks
  • Layer 7 attacks

Vulnerability & Exposure Management

• Oversee vulnerability management programs across applications, cloud environments, and infrastructure.
• Lead penetration testing initiatives and coordinate remediation efforts.
• Drive attack surface reduction programs.
• Partner with engineering teams to prioritize and address security risks.

Incident Response & Security Operations

• Act as a senior advisor during security incidents.
• Support containment, investigation, root cause analysis, and remediation activities.
• Participate in post-incident reviews and strategic improvement initiatives.

AI & Emerging Technology Security

• Design and implement security controls for AI/ML platforms and applications.
• Evaluate AI-specific risks such as:
  • Prompt Injection
  • Data Leakage
  • Model Abuse
  • Unauthorized Model Access
  • Supply Chain Risks
• Establish security guardrails aligned with OWASP Top 10 for LLM Applications and emerging AI security standards.
• Evaluate and integrate AI-powered security tools to improve threat detection and security automation.

Cross-Functional Leadership

• Serve as a trusted security advisor for engineering, product, and platform teams.
• Drive security awareness and adoption across the organization.
• Mentor engineers and security practitioners on secure architecture and design practices.
• Influence security strategy and long-term roadmap development.

 

Must-Have Qualifications

Experience

• 4+ years of experience in Cybersecurity, Application Security/PT.
• Strong understanding of modern application architectures and distributed systems.

Technical Expertise

• Security Architecture and Secure Design Reviews
• Threat Modeling (STRIDE, PASTA, ATT&CK)
• Application Security & Secure SDLC
• Cloud Security (GCP / AWS)
• Kubernetes & Container Security
• API Security
• Identity & Access Management
• Security Automation & DevSecOps
• Vulnerability Management & Penetration Testing

AI Security
