Job summary

Accenture in Sydney seeks an experienced Enterprise Security Architect to lead delivery across endpoint protection, DLP, and vulnerability management, aligning MLS and ZTA patterns.

You will govern target-state architectures, drive integration with Trellix and Tenable, and provide technical guidance to cross-functional teams.

The role requires government-environment experience and a track record of translating policy into practical architecture and roadmaps.

Qualifications

• Experience in enterprise security architecture and complex technology delivery.
• Strong knowledge of Trellix and Tenable platforms in large enterprise or government environments.
• Ability to translate security policy into architecture patterns, roadmaps and practical delivery patterns.
• Experience integrating security platforms with SIEM, SOAR, ITSM, identity and access management.

Responsibilities

• Own the enterprise security architecture and end-to-end delivery direction for endpoint protection, application control, DLP, and vulnerability management capabilities.
• Define and govern target-state architectures, transition states, reference patterns, security standards, integration patterns, and implementation guardrails across Trellix and Tenable platforms.
• Provide technical and delivery leadership to architects, engineers, process consultants, analysts, testers, vendors, and operational support teams.
• Lead the architecture, implementation, integration, and optimisation of Trellix capabilities, including endpoint protection, endpoint detection and response, application and change control, data loss prevention, device control, policy management, and centralised administration.
• Lead the architecture, implementation, integration, and operationalisation of Tenable capabilities, including asset discovery, vulnerability assessment, credentialed scanning, risk-based prioritisation, exposure management, remediation tracking, compliance assessment, and executive reporting.
• Ensure endpoint protection, application control, DLP, and vulnerability management capabilities are designed as complementary controls and integrated with identity, network, data, cloud, application, SIEM, SOAR, ITSM, configuration management, and security operations services.
• Define security architecture patterns that support MLS outcomes, including security classification and labelling, data-centric security, mandatory and attribute-based access control, trusted enforcement points, need-to-know controls, separation of security domains, cross-domain information flows, and high-assurance auditability.
• Maintain architecture alignment across the ZTA technology pillars of user, device, application and workload, data, network and environment, visibility and analytics, and automation and orchestration.
• Ensure access decisions consider user identity, clearance, role, device posture, workload identity, data classification, mission context, environmental risk, and continuous security telemetry.
• Establish architectural approaches for least privilege, explicit verification, continuous authorisation, micro-segmentation, policy enforcement, attack-surface reduction, lateral-movement prevention, and continuous control assessment.
• Develop capability roadmaps and maturity plans that sequence foundational, intermediate, and advanced MLS and ZTA outcomes across people, process, technology, governance, and operations.
• Lead technical planning, solution decomposition, delivery sequencing, dependency management, design assurance, and resolution of cross-platform architecture issues.
• Review and approve architecture descriptions, decision briefs, system designs, interface specifications, security patterns, configuration standards, test strategies, operational models, and transition-to-service artefacts.
• Identify and manage technical risks, capability gaps, product constraints, integration dependencies, security exceptions, and residual risks.
• Ensure designs align with applicable Australian Government security policy, assurance requirements, enterprise standards, and operational support models.
