Security Platform Engineer

Security Engineer, runZero Platform

Location: Sydney

Contract: 6 Months + Highly Likely Extensions

About the Opportunity

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

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

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

Required Skills and Experience

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

Desirable Experience

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

What's on Offer

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