Enterprise Security Architect

Enterprise Security Architecture – Lead

Define enterprise security architecture standards, create security patterns and frameworks, establish security controls by tier, and provide the security templates that enable secure‑by‑design solutions. This role creates security patterns and standards, not operational security implementation.

• Policy translator: Convert Info Sec policies into practical architectural patterns that solution architects can apply
• Security‑by‑tier architect: Define exactly what security controls are required for each application tier (Tier 0/1/2/3)
• Zero‑trust strategist: Lead the enterprise adoption of zero‑trust architecture through patterns and templates
• Strategic partnership: Bridge between architecture and operational security (Info Sec team)

• Define security architecture reference architectures (zero‑trust, defense‑in‑depth)
• Create security patterns library (authentication & authorization patterns, API security patterns, data protection patterns, network security patterns, application security patterns)
• Establish security controls by application tier (Tier 0: HSM, 24/7 SOC, multi‑region DR; Tier 1: MFA, encryption at rest/transit, WAF; Tier 2/3: standard security controls)
• Define identity and access management (IAM) patterns
• Document encryption and key management standards

• Develop threat modeling framework (STRIDE, PASTA templates)
• Create security testing framework (SAST, DAST, penetration testing standards)
• Establish Dev Sec Ops  patterns and shift‑left security standards
• Define security compliance frameworks (SOC 2, ISO 27001, GDPR, HIPAA patterns)

• Review solution architectures for security pattern compliance
• Conduct threat modeling for strategic initiatives
• Define security architecture review criteria
• Translate Info Sec policies into architectural patterns
• Establish security exception process

• Train solution architects on security patterns
• Maintain security pattern catalog
• Partner with Info Sec on security requirements

• Bachelor's degree in Computer Science, Information Security, or related field

• 7+ years in security architecture, enterprise architecture, or cybersecurity
• 5+ years creating enterprise security standards and patterns
• Proven experience with zero‑trust architecture and secure design patterns
• Experience establishing security controls frameworks and compliance patterns
• Track record conducting threat modeling and security architecture reviews

• CISSP (Certified Information Systems Security Professional) – required
• TOGAF certification – preferred
• SABSA certification – preferred
• Cloud security certification (AWS Security Specialty, Azure Security Engineer, Google Cloud Security Engineer) – preferred
• CISM or CISA – preferred

• Experience in highly regulated industries (healthcare, finance, government)
• Background in penetration testing or offensive security
• Experience implementing zero‑trust at enterprise scale
• Deep knowledge of compliance frameworks and audit processes

• Security pattern adoption rate 80%+ for new solutions
• 100% of strategic initiatives complete threat modeling
• Security controls by tier framework established with 90%+ compliance
• Publish 10+ security patterns in catalog
• Conduct 50+ architecture security reviews
• Reduce security incident rate by 30% for pattern‑compliant solutions

• Security architecture reference architectures
• Security pattern library
• Security controls by application tier
• Zero‑trust implementation patterns
• IAM patterns and templates
• Threat modeling framework
• Dev Sec Ops  standards
• Security review criteria

• Info Sec team (operational security, policy translation)
• Solution architects (apply security patterns)
• Cloud & Platform Architect (security controls by tier alignment)
• Compliance and audit teams

• Architecture Review Board (bi‑weekly)
• Security Architecture Review (weekly – you lead this)
• Pattern Review Sessions (bi‑weekly)

Our Enterprise Architecture team operates on principles of collaboration, excellence, and innovation:

• Pattern‑first mindset: We create reusable blueprints that enable consistency and quality
• Partnership model: We work alongside operational teams (App Dev, Data Platform, Infrastructure, Info Sec) as strategic partners
• Continuous improvement: Patterns evolve based on feedback from implementation
• Enablement focus: Success means solution architects effectively apply our patterns
• Executive backing: Strong leadership support for architecture governance and standards
