• A leading technology consultancy is seeking an experienced

Security Engineer to design, implement and operate an enterprise asset-discovery capability using run Zero .

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, Io T and relevant operational technology environments.

Key Responsibilities

• Design and implement the run Zero 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, Io T 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 run Zero with enterprise platforms such as CMDB, Service Now, 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 run Zero 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, Service Now, 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, Io T or operational technology environments.
• Knowledge of Service Now, 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.
