Security Engineer, runZero Platform

\n

Location: Sydney

\n

Contract: 6 Months + Highly Likely Extensions

About the Opportunity \n

A leading technology consultancy is seeking an experienced Security Engineer to design, implement and operate an enterprise asset-discovery capability using runZero .

\n

This is a hands‑on engineering role combining platform configuration, security automation, systems integration and site reliability engineering. You will help establish a scalable operating model that delivers accurate asset visibility across corporate, data‑centre, cloud, remote‑access, network, IoT and relevant operational technology environments.

Key Responsibilities \n

\n
• Design and implement the runZero operating model, including environments, access controls, roles, sites, asset groups, tags and naming standards.
\n
• Configure discovery coverage across corporate, cloud, data‑centre, remote‑access, network, IoT and relevant OT environments.
\n
• Develop active‑scanning, passive‑discovery and integration patterns suited to different network zones and operational risk profiles.
\n
• Establish appropriate scanning standards, approval controls, maintenance windows and exception processes.
\n
• Configure asset classification, ownership, business context, criticality and lifecycle information.
\n
• Develop reusable configuration patterns and maintain separation between production, testing and experimental changes.
\n
• Integrate runZero with enterprise platforms such as CMDB, ServiceNow, Tenable, EDR, NAC, DNS/DHCP, cloud services, identity systems, SIEM and SOAR.
\n
• Implement secure API‑based data ingestion and egress using service identities and least‑privilege access.
\n
• Automate asset reconciliation, deduplication, enrichment, ownership mapping and data‑quality validation.
\n
• Define integration contracts, schemas, field mappings, error handling, retry behaviour and support expectations.
\n
• Build automated workflows for newly discovered assets, exposed services, control gaps, unauthorised devices and material changes.
\n
• Use APIs, webhooks, scripts and workflow platforms to streamline administration and improve response times.
\n
• Automate scan scheduling, configuration validation, asset tagging, reporting and lifecycle management.
\n
• Design safe, repeatable automation that avoids duplicate records, tickets and configuration drift.
\n
• Apply version control, peer review, automated testing, release controls and rollback procedures to platform changes.
\n
• Establish service indicators, dashboards and alerts covering discovery coverage, data freshness, integration health, scanning and workflow reliability.
\n
• Develop operational runbooks and support backup, recovery, disaster‑recovery and business‑continuity planning.
\n
• Implement role‑based access, privileged‑access controls, administrative separation and auditable change history.
\n
• Support architecture, security, privacy, risk and control‑assurance reviews.
\n

Required Skills and Experience \n

\n
• Strong experience engineering and operating enterprise security or asset‑discovery platforms.
\n
• Practical expertise with runZero or a comparable asset‑discovery and attack‑surface visibility platform.
\n
• Strong knowledge of active scanning, passive discovery and network‑zone risk management.
\n
• Experience integrating security platforms with CMDB, ServiceNow, vulnerability‑management, endpoint, network, cloud, identity and SIEM/SOAR technologies.
\n
• Demonstrated API, webhook, scripting and workflow‑automation capability.
\n
• Experience with asset reconciliation, deduplication, enrichment and data‑quality controls.
\n
• Sound understanding of least‑privilege access, service identities, secrets management and role‑based access control.
\n
• Experience applying infrastructure‑as‑code or configuration‑as‑code practices, version control, testing and controlled releases.
\n
• Strong operational knowledge across monitoring, alerting, incident runbooks, recovery, performance and capacity management.
\n

Desirable Experience \n

\n
• Experience supporting asset discovery across cloud, IoT or operational technology environments.
\n
• Knowledge of ServiceNow, Tenable, EDR, NAC, DNS/DHCP, SIEM and SOAR integrations.
\n
• Experience designing event‑driven and idempotent automation.
\n
• Familiarity with security architecture reviews, privacy assessments, risk assessments and regulatory control requirements.
\n

What’s on Offer \n

\n
• A technically challenging role with significant ownership of an enterprise security platform.
\n
• The opportunity to build scalable discovery, integration and automation capabilities.
\n
• Broad collaboration across security, infrastructure, network, cloud and application teams.
\n
• A role spanning engineering delivery, automation, operational resilience and security governance.
