Core Responsibilities

Primary Functions

Define, document, and maintain the enterprise security architecture roadmap and standards by translating business objectives and risk appetite into security principles, patterns, and reference architectures for cloud, on-premises, hybrid, and multi-cloud environments.
Lead architecture reviews and design sessions for critical projects, providing security requirements, threat modeling, secure-by-design recommendations, and mitigation strategies to engineering and application teams.
Architect and govern identity and access management (IAM) solutions, including single sign-on (SSO), multi-factor authentication (MFA), privileged access management (PAM), and role-based access control (RBAC) frameworks to minimize privilege risk and ensure least-privilege enforcement.
Design and operationalize a Zero Trust Architecture (ZTA) approach across network, application, and identity layers; define micro-segmentation, device posture, continuous authentication, and policy enforcement points.
Develop and implement cloud security architectures and guardrails for AWS, Azure, and GCP including secure landing zones, network topologies, encryption strategies, secret management, and container/kubernetes security patterns.
Establish secure application architecture patterns and integrate security into the software development lifecycle (SDLC) by defining secure coding standards, static and dynamic analysis tooling, and developer-friendly remediation workflows.
Design logging, monitoring, and detection architectures that incorporate SIEM/SOAR (e.g., Splunk, Elastic, Azure Sentinel), endpoint detection & response (EDR), and network detection to ensure comprehensive threat detection, incident response readiness, and forensic capabilities.
Define and roll out enterprise-wide encryption, key management (KMS/HSM/PVK), certificate lifecycle management, and data protection strategies for data at rest, in transit, and in use.
Lead threat modeling and attack surface analysis workshops for high-risk systems, producing prioritized findings, risk metrics, and concrete architectural remediation plans.
Design secure network architectures including next-generation firewalls, intrusion prevention, VPN, SD-WAN, SASE, CASB integrations, and secure remote access solutions that balance security, performance, and business continuity.
Own vulnerability management architecture: integrate scanning, prioritization, and remediation orchestration (CVSS risk modeling, compensating controls, and exception workflows) with engineering remediation SLAs.
Partner with risk and compliance teams to map architecture controls to frameworks and regulations (NIST CSF, ISO 27001, SOC2, PCI-DSS, HIPAA), produce evidence for audits, and design compensating controls where necessary.
Create and maintain detailed architecture artifacts: diagrams, decision records, standards, playbooks, and runbooks that are consumable by engineering, operations, and leadership.
Evaluate and select security technologies and vendors—leading proof-of-concepts, total cost of ownership analyses, and procurement support while ensuring alignment to architecture principles and long-term roadmap.
Lead cross-functional security design reviews for mergers, acquisitions, and third-party integrations: perform security due diligence, integration risk assessment, and define remediation/segregation requirements.
Drive automation and Infrastructure as Code (IaC) for security provisioning and compliance (Terraform, CloudFormation, ARM templates) to ensure repeatable, auditable, and scalable security deployments.
Define metrics and KPIs for security architecture effectiveness (mean time to detect/contain, coverage of controls, risk reduction metrics) and report them to senior leadership to inform strategic decisions.
Mentor and coach engineering teams, security engineers, and junior architects on secure architecture best practices, secure coding, threat-informed design, and risk-based decision making.
Coordinate with incident response and SOC teams to ensure the architecture supports detection, containment, and recovery requirements; participate in tabletop exercises and post-incident architecture reviews to harden systems.
Drive cost-effective security design by balancing risk, usability, scalability, and operational overhead; recommend phased implementation plans tied to business priorities and measurable outcomes.
Define and enforce API security patterns, secure integration approaches, and authorization models (OAuth, OpenID Connect, JWT) across internal and external interfaces.
Lead encryption key lifecycle policies and integration with cloud KMS, HSMs, and hardware-backed key stores while ensuring compliance with data residency and cryptographic standards.
Collaborate with data architects to classify sensitive data, design data loss prevention (DLP) controls, tokenization, access controls, and secure analytics patterns that support both privacy and business analytics needs.
Establish a reusable control catalog and mapping to platform services to enable platform teams and developers to adopt secure defaults and accelerate secure product delivery.

Secondary Functions

Provide architecture input for vendor contracts, SLAs, and security addenda to ensure third-party risks are mitigated via architecture and contractual controls.
Develop and deliver targeted security architecture training and brown-bag sessions for engineering and product teams to accelerate adoption of secure patterns.
Support procurement and product selection by creating evaluation criteria, security checklists, and performing integration risk assessments.
Engage with business continuity and disaster recovery planning to ensure architecture supports resilient, secure recovery objectives and preservation of key security controls during failover.
Participate in internal and external audits by preparing architecture documentation, control mappings, and remediation plans to address audit findings.
Contribute to the security roadmap and budget planning process by estimating effort, defining priority initiatives, and articulating business value and risk reduction.
Stay current with emerging threats, technology trends, compliance changes, and research new architecture approaches (SSE, Confidential Computing, Secure Access Service Edge) that can be applied to the enterprise.
Provide hands-on guidance in difficult escalations requiring architecture-level decisions, including live incident consultations or critical change windows.
