Senior Cybersecurity Architect

Role Overview

We are seeking a highly experienced Senior Cybersecurity Architect to own and evolve client's security architecture strategy and operating model.

This role serves as the senior security design authority, responsible for defining secure-by-design reference architectures, standards, patterns, and guardrails that engineering teams adopt by default. The position focuses on architecture leadership, threat modeling, security design decisions, and AI-era security challenges rather than traditional compliance-driven activities.

The successful candidate will work closely with Security Engineering, AI Security, IAM, Cloud Security, Product Security, and executive stakeholders to establish a scalable, resilient, and future-proof cybersecurity architecture across the organization.

Key Responsibilities

• Define, maintain, and evolve enterprise security architecture standards and reference architectures.
  
• Establish secure-by-design patterns, paved roads, and security guardrails across cloud, infrastructure, identity, application, and data domains.
  
• Act as the senior escalation point for security architecture decisions and high-risk design reviews.
  
• Lead threat modeling exercises for critical systems, platforms, APIs, AI components, and business processes.
  
• Design defense-in-depth security architectures aligned with modern cloud and AI-enabled environments.
  
• Drive adoption of security automation, policy-as-code, DevSecOps practices, and AI-assisted security reviews.
  
• Maintain architecture decision records, exceptions, and governance processes.
  
• Translate incidents, emerging threats, and industry developments into architectural improvements.
  
• Provide technical leadership, mentoring, and guidance to security and engineering teams.
  
• Support customer assurance and trust initiatives through architecture documentation and security narratives.
  
• Collaborate with AI Security teams to address emerging AI and agentic system risks.
  
• Contribute to the long-term cybersecurity strategy and roadmap.
  

Requirements

• Minimum 10 years of experience in Information Security.
  
• Extensive experience in Security Architecture and Secure-by-Design methodologies.
  
• Proven track record defining enterprise-scale security reference architectures and standards.
  
• Strong expertise across cloud security, application security, infrastructure security, IAM, networking, and data protection.
  
• Experience conducting threat modeling and architecture risk assessments.
  
• Strong knowledge of cloud-native security services and modern security tooling.
  
• Experience with DevSecOps, CI/CD security, policy-as-code, and automation frameworks.
  
• Strong understanding of AI-related security risks and governance frameworks.
  
• Familiarity with AI security concepts including:
  • Prompt Injection
    
  • Agentic Systems Security
    
  • Machine Identity Security
    
  • Non-Human Identity
    
  • AI Control Plane Security
    
  • MLSecOps
    
• Deep understanding of security frameworks including:
  • ISO 27001

  • NIST AI RMF
    
  • ISO 42001
    
  • EU AI Act
    
• Excellent written and verbal communication skills in English.
  
• Ability to influence senior stakeholders and drive architectural decisions across global teams.
  

Preferred Qualifications

• CISSP, CISM, or CCSP certifications.
  
• AWS Certified Security – Specialty.
  
• Microsoft AZ-500 certification.
  
• Experience building or maturing enterprise security architecture functions.
  
• Experience operating within large multinational organizations.
  
• Exposure to AI-assisted security design and review platforms.
  
• Knowledge of agentic AI architectures and secure AI development practices.
  

Preferred Profile

• Strategic thinker with strong technical depth.
  
• Comfortable making risk-based decisions in complex environments.
  
• Strong leadership and influencing skills.
  
• Passionate about secure-by-design principles.
  
• Highly collaborative and capable of working across multiple geographies and business functions.
  
• Enthusiastic about emerging technologies, cybersecurity innovation, and AI-enabled security transformation.
